Hidden diversity of Pestalotiopsis and Neopestalotiopsis (Amphisphaeriales, Sporocadaceae) species allied with the stromata of entomopathogenic fungi in Taiwan. MycoKeys 2024; 101:275-312. [PMID: 38333551 PMCID: PMC10851163 DOI: 10.3897/mycokeys.101.113090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 01/12/2024] [Indexed: 02/10/2024] Open
Abstract
Pestalotiopsissensu lato, commonly referred to as pestalotiopsis-like fungi, exhibit a broad distribution and are frequently found as endophytes, saprobes and pathogens across various plant hosts. The taxa within pestalotiopsis-like fungi are classified into three genera viz. Pestalotiopsis, Pseudopestalotiopsis and Neopestalotiopsis, based on the conidial colour of their median cells and multi-locus molecular phylogenies. In the course of a biodiversity investigation focusing on pestalotiopsis-like fungi, a total of 12 fungal strains were identified. These strains were found to be associated with stromata of Beauveria, Ophiocordyceps and Tolypocladium in various regions of Taiwan from 2018 to 2021. These strains were evaluated morphologically and multi-locus phylogenetic analyses of the ITS (internal transcribed spacer), tef1-α (translation elongation factor 1-α) and tub2 (beta-tubulin) gene regions were conducted for genotyping. The results revealed seven well-classified taxa and one tentative clade in Pestalotiopsis and Neopestalotiopsis. One novel species, Pestalotiopsismanyueyuanani and four new records, N.camelliae-oleiferae, N.haikouensis, P.chamaeropis and P.hispanica, were reported for the first time in Taiwan. In addition, P.formosana and an unclassified strain of Neopestalotiopsis were identified, based on similarities of phylogeny and morphology. However, the data obtained in the present study suggest that the currently recommended loci for species delimitation of pestalotiopsis-like fungi do not deliver reliable or adequate resolution of tree topologies. The in-vitro mycelial growth rates of selected strains from these taxa had an optimum temperature of 25 °C, but growth ceased at 5 °C and 35 °C, while all the strains grew faster under alkaline than acidic or neutral pH conditions. This study provides the first assessment of pestalotiopsis-like fungi, associated with entomopathogenic taxa.

Abstract
Following an EFSA commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) imported from China, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis microspora, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen was reported on a wide range of monocotyledonous, dicotyledonous and gymnosperms, either cultivated or wild plant species, causing various symptoms such as leaf spot, leaf blight, scabby canker, fruit spot, pre- and post-harvest fruit rot and root rot. In addition, the fungus was reported as an endophyte on a wide range of asymptomatic plant species. This pest categorisation focuses on the hosts that are relevant for the EU and for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequencing analyses. Pestalotiopsis microspora was reported in Africa, North, Central and South America, Asia and Oceania. In the EU, it was reported in the Netherlands. There is a key uncertainty on the geographical distribution of P. microspora worldwide and in the EU, because of the endophytic nature of the fungus, the lack of surveys, and because in the past, when molecular tools were not fully developed, the pathogen might have been misidentified as other Pestalotiopsis species or other members of the Pestalodiopsidaceae family based on morphology and pathogenicity tests. Pestalotiopsis microspora is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting, fresh fruits, bark and wood of host plants as well as soil and other growing media associated with plant debris are the main pathways for the entry of the pathogen into the EU. Host availability and climate suitability in parts of the EU are favourable for the establishment and spread of the pathogen. The introduction and spread of the pathogen into the EU are expected to have an economic and environmental impact where susceptible hosts are grown. Phytosanitary measures are available to prevent the introduction and spread of the pathogen into the EU. Unless the restricted distribution in the EU is disproven, Pestalotiopsis microspora satisfies all the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.

Abstract
This paper represents the results of screening a diversity of fungal endophytes associated with Vitis vinifera leaves and canes in the Czech Republic. The characterization of strains is based on morphological and phylogenetic analyses of ITS, EF1α and TUB2 sequence data. Our strain selection covers 16 species and seven orders belonging to Ascomycota and Basidiomycota. Together with ubiquitous fungi, we report on several poorly known plant-associated fungi, Angustimassarina quercicola (= A. coryli, a synonym proposed in this study) and Pleurophoma pleurospora. Other species, such as Didymella negriana, D. variabilis, Neosetophoma sp. (species identical or sister to N. rosae), Phragmocamarosporium qujingensis and Sporocadus rosigena, have so far been little known and rarely found, but are frequent on V. vinifera in different parts of the world and obviously belong to a microbiota with a strong preference for this plant. Detailed taxonomical identification allowed us to identify species with apparent stable associations with V. vinifera, for which further interactions with V. vinifera can be expected. Our study is the first to focus on V. vinifera endophytes in Central Europe and expands the knowledge about their taxonomy, ecology and geography.

Abstract
Following the commodity risk assessments of bonsai plants from China consisting of Pinus parviflora grafted on P. thunbergii performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis disseminata, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen has been reported on herbaceous, woody and ornamental plants causing symptoms such as leaf blight, shoot blight, seedling blight, pod canker, pre- and post-harvest fruit rot, and gummosis. Moreover, the fungus was reported as an endophyte on a wide range of asymptomatic hosts. The pathogen is present in Africa, North and South America, Asia, Europe and Oceania. It has been reported from the EU, with a restricted distribution (Portugal). There is a key uncertainty on the geographical distribution of P. disseminata in the EU and worldwide, because of the endophytic nature of the fungus, the lack of surveys and since the pathogen might have been misidentified based only on morphology and pathogenicity tests. The pathogen is not included in Commission Implementing Regulation (EU) 2019/2072. This pest categorisation focuses on those hosts that are relevant for the EU and for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequence analysis. Plants for planting, fresh fruits, bark and wood of host plants as well as soil and other plant growing media are the main pathways for the entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the establishment of the pathogen. Despite the low aggressiveness observed in most reported hosts, and the fact that P. disseminata may colonise plants as an endophyte, its introduction and spread in the EU may have an economic and environmental impact (with a key uncertainty) where susceptible hosts are grown. Phytosanitary measures are available to prevent the introduction and spread of the pathogen. The Panel cannot conclude on whether P. disseminata satisfies all the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest, because of the key uncertainties on the restricted distribution in the EU and the magnitude of the impact.

Abstract
Appressoria are specialized structures formed by certain phytopathogenic fungi during the early stages of the infection process. Over the years, significant advancements have been made in understanding the formation, types, and functions of appressoria. Besides being formed primarily by fungal pathogens, many studies have reported their occurrence in other life modes such as endophytes, epiphytes, and saprobes. In this study, we observed the formation of appressoria in fungal genera that have been found associated with leaf spots and, interestingly, by a saprobic species. We used morphological descriptions and illustrations, molecular phylogeny, coalescent-based Poisson tree processes (PTP) model, inter- and intra-species genetic distances based on their respective DNA markers, and Genealogical Concordance Phylogenetic Species Recognition Analysis (GCPSR) to establish a new species (Pseudoplagiostoma jasmini), a Ciliochorella sp., and a new host record (Coniella malaysiana). The Ciliochorella sp. is reported as a saprobe, while Pseudoplagiostoma jasmini and Coniella malaysiana were found to be associated with leaf spots of Jasminum species. All three taxa produce appressoria, and this is the first study that reports the formation of appressoria by a Ciliochorella sp. and a Pseudoplagiostoma sp.

Abstract
The genus Ciliochorella is a group of pestalotioid fungi, which typically occurs in subtropical and tropical areas. Species from the Ciliochorella genus play important roles in the decomposition of litter. In this study, we introduce two new species (Ciliochorellachinensissp. nov. and C.savannicasp. nov.) that were found on leaf litter collected from savanna-like vegetation in hot dry valleys of southwestern China. Phylogenetic analyses of combined LSU, ITS and tub2 sequence datasets indicated that C.chinensis and C.savannica respectively form a distinct clade within the Ciliochorella genus. The comparison of the morphological characteristics indicated that the two new species are well differentiated within this genus species. Analysis of the evolutionary history suggests that Ciliochorella originated from the Eurasian continent during the Paleogene (38 Mya). Further, we find that both new species can produce cellulase and laccase, playing a decomposer role.

Abstract
The deviation of conventional fungal niches is an important factor in the implications of hidden fungal diversity and global fungal numbers. The Xylariomycetidae (Sordariomycetes, Ascomycota), which is also referred to as xylarialean taxa, has a wide range of species that demonstrate a high degree of variation in their stromatic characteristics, showing either conspicuous or inconspicuous forms. In this study, samples were collected while focusing on temporal and spatial parameters and substrate characteristics. Based on internal transcribed spacer (ITS), 28S large subunit rDNA (LSU), RNA polymerase II second largest subunit (RPB2), and β-tubulin (TUB2) multigene phylogeny and morphology, five new species are introduced as Muscodor brunneascosporus, M. lamphunensis (Xylariaceae), Nigropunctata hydei, N. saccata (Incertae sedis), and Xenoanthostomella parvispora (Gyrotrichaceae). Plant substrates in the early stages of decay and attached to the host were feasible sample niches, with an emphasis on the collection of inconspicuous, hidden xylarialean species. The appearance of inconspicuous saprobic xylarialean forms during the rainy season may be linked to the change in nutritional mode, from endophytic mode during the dry season to saprobic in the wet. Therefore, it would be fascinating to concentrate future research on how seasonal fluctuations affect nutritional mode shifts, especially in northern Thailand, which would provide the optimal spatial characteristics. In order to establish a comprehensive linkage between endophytic and saprobic modes, it is imperative to have a substantial representation of endophytic isolate sequences resembling inconspicuous xylariaceous fungi within publicly accessible databases.

Abstract
The frequency of flow intermittency and drying events in Alpine rivers is expected to increase due to climate change. These events can have significant consequences for stream ecological communities, though the effects of reduced flow conditions on microbial communities of decomposing allochthonous leaf material require additional research. In this study, we investigated the bacterial and fungal communities associated with the decomposition of two common species of leaf litter, chestnut (Castanea sativa), and oak (Quercus robur). A sampling of experimentally placed leaf bags occurred over six collection dates (up to 126 days after placement) at seven stream sites in the Western Italian Alps with historically different flow conditions. Leaf-associated bacterial and fungal communities were identified using amplicon-based, high-throughput sequencing. Chestnut and oak leaf material harbored distinct bacterial and fungal communities, with a number of taxonomic groups differing in abundance, though bacterial community structure converged later in decomposition. Historical flow conditions (intermittent vs perennial rivers) and observed conditions (normal flow, low flow, ongoing drying event) had weaker effects on bacterial and fungal communities compared to leaf type and collection date (i.e., length of decomposition). Our findings highlight the importance of leaf characteristics (e.g., C:N ratios, recalcitrance) to the in-stream conditioning of leaf litter and a need for additional investigations of drying events in Alpine streams. This study provides new information on the microbial role in leaf litter decomposition with expected flow changes associated with a global change scenario.

Abstract
Species of Pestalotiopsis were mainly introduced as endophytes, plant pathogens or saprobes from various hosts. In this study, ten strains were isolated from Ficus macrocarpa, Phoebe zhennan and Spatholobus suberectus in China. Based on multilocus phylogenies from the internal transcribed spacer (ITS), the partial translation elongation factor 1-alpha gene (tef1α) and the partial beta-tubulin gene (tub2), in conjunction with morphological characteristics, we describe three new species, viz., Pestalotiopsis ficicola sp. nov., P. phoebes sp. nov. and P. spatholobi sp. nov.

[PMID: 37014218 PMCID: PMC10269674 DOI: 10.1128/spectrum.00042-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 02/14/2023] [Indexed: 04/05/2023] Open
Abstract
Pestalotioid fungi have been frequently studied with respect to their morphology, molecular phylogeny, and pathogenicity. Monochaetia is a pestalotioid genus that is morphologically characterized by 5-celled conidia with single apical and basal appendages. In the present study, fungal isolates were obtained from diseased leaves of Fagaceae hosts in China in 2016 to 2021 and identified based on morphology and phylogenetic analyses of the 5.8S nuclear ribosomal DNA gene with the two flanking internal transcribed spacer (ITS) regions, the nuclear ribosomal large subunit (LSU) region, the translation elongation factor 1-α (tef1) gene, and the β-tubulin (tub2) gene. As a result, five new species are proposed here, namely, Monochaetia hanzhongensis, Monochaetia lithocarpi, Monochaetia lithocarpicola, Monochaetia quercicola, and Monochaetia shaanxiensis. In addition, pathogenicity tests for these five species and Monochaetia castaneae from Castanea mollissima were conducted with detached leaves of Chinese chestnut. Results demonstrated that only M. castaneae successfully infected the host C. mollissima and caused brown lesions. IMPORTANCE Monochaetia is a pestalotioid genus, with members that are commonly known as leaf pathogens or saprobes; some strains were isolated from air, in which case their natural substrate is so far unknown. Fagaceae represents an ecologically and economically important plant family that is widely distributed in the Northern Hemisphere, including an important tree crop species, Castanea mollissima, which is widely cultivated in China. In the present study, diseased leaves of Fagaceae in China were investigated, and five new Monochaetia species were introduced based on morphology and phylogeny of combined ITS, LSU, tef1, and tub2 loci. Additionally, six species of Monochaetia were inoculated onto healthy leaves of the crop host Castanea mollissima to test their pathogenicity. The present study provides significant data on the species diversity, taxonomy, and host range of Monochaetia and enhances our understanding of leaf diseases of Fagaceae hosts.

Abstract
Leaf litter is an essential functional aspect of forest ecosystems, acting as a source of organic matter, a protective layer in forest soils, and a nurturing habitat for micro- and macro-organisms. Through their successional occurrence, litter-inhabiting microfungi play a key role in litter decomposition and nutrient recycling. Despite their importance in terrestrial ecosystems and their abundance and diversity, information on the taxonomy, diversity, and host preference of these decomposer taxa is scarce. This study aims to clarify the taxonomy and phylogeny of four saprobic fungal taxa inhabiting Dipterocarpus alatus leaf litter. Leaf litter samples were collected from Doi Inthanon National Park in Chiang Mai, northern Thailand. Fungal isolates were characterized based on morphology and molecular phylogeny of the nuclear ribosomal DNA (ITS, LSU) and protein-coding genes (tub2, tef1-α, rpb2). One novel saprobic species, Ciliochorella dipterocarpi, and two new host records, Pestalotiopsis dracontomelon and Robillarda australiana, are introduced. The newly described taxa are compared with similar species, and comprehensive descriptions, micrographs, and phylogenetic trees are provided.

Redisposition of apiosporous genera Induratia and Muscodor in the Xylariales, following the discovery of an authentic strain of Induratia apiospora. BOTANICAL STUDIES 2023; 64:8. [PMID: 37052736 PMCID: PMC10102272 DOI: 10.1186/s40529-023-00372-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 03/25/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND The genus Induratia is based on Induratia apiospora, a xylarialean pyrenomycete from New Zealand with clypeate uniperitheciate stromata, hyaline apiospores and a nodulisporium-like anamorph. However, because of the lack of DNA data from the generic type, its phylogenetic affinities have remained unresolved. Recently, two fungal species with teleomorphs strikingly similar to Induratia were discovered in Thailand. However, they did not produce an anamorph and were found to be phylogenetically close to the species classified within the hyphomycete genus Muscodor, which was described after Induratia. Therefore, in 2020 the species of Muscodor were transferred to Induratia, and a new family Induratiaceae was proposed. RESULTS We have encountered an unpublished ex-holotype strain of Induratia apiospora among the holdings of the ATCC collection, enabling detailed morphological and molecular phylogenetic investigations. We observed the characteristic nodulisporium-like anamorph described in the original publication. Phylogenetic analyses of multigene sequence data revealed a close relationship of Induratia apiospora to the Barrmaeliaceae, while a close relationship to the Induratia species formerly classified within Muscodor was rejected. CONCLUSIONS We here classify Induratia apiospora within the Barrmaeliaceae and consider Induratiaceae to be synonymous with the former. As the holotype specimen of Induratia apiospora is apparently lost, an isotype specimen from WSP is selected as lectotype. We also propose that the genus Muscodor is resurrected within the Xylariaceae, and formally transfer several Induratia species to Muscodor.

Abstract
In this paper, a total of 26 pestalotioid isolates associated with different medicinal plants from southwest China and Thailand were studied. Based on morphological examinations and multigene analyses of three gene loci (ITS, tef1-α, and tub2), these 26 isolates represent 17 species distributed in three genera, including seven new species and eight new records. The concatenated three loci tree was used to infer the occurrence of sexual recombination within each pestalotioid genus through the pairwise homoplasy index (PHI) test implemented in SplitsTree. Further, simplifying the description of pestalotioid species is discussed, and a checklist for pestalotioid species associated with medicinal plants worldwide is provided. IMPORTANCE Pestalotioid species are an important fungal group, occurring commonly as plant pathogens, endophytes, and saprophytes. The study of pestalotioid species associated with medicinal plants is significant for agriculture, industry, and pharmaceutical industry but remains poorly studied. In this study, we report 17 pestalotioid species related to medicinal plants based on morphology and molecular analyses. Our study significantly enriches the species richness of pestalotioids and provides a basis for follow-up studies.

Abstract
The fungal strain belonging to the genus Monochaetia of the family Sporocadaceae was isolated from hairy long-horned toad beetle (Moechotypa diphysis) during the screening of microfungi associated with insects from Gangwon Province, Korea. The strain KNUF-6L2F produced white, light brown to dirty black surface, and olivaceous green colonies with the higher growth, while the closest strain M. ilicis KUMCC 15-0520T were light brown to brown, and M. schimae SAUCC 212201T light brown to brown toward center. The strain KNUF-6L2F produced shorter (5.7-14.0 μm) apical appendages than M. ilicis (6.0-24.0 μm), but similar to M. schimae (7.0-12.5 μm). Three median cells of KNUF-6L2F were light brown to olivaceous green, whereas brown and olivaceous cells were observed from M. ilicis and M. schimae, respectively. And the strain KNUF-6L2F produced larger conidiogenous cells than M. ilicis and M. schimae. Additionally, phylogenetic analyses based on molecular datasets of internal transcribed spacer (ITS) regions, translation elongation factor 1-alpha (TEF1α), and β-tubulin (TUB2) genes corroborated the strain's originality. Thus, the strain is different from other known Monochaetia species, according to molecular phylogeny and morophology, hence we suggested the new species Monochaetia mediana sp. nov. and provided a descriptive illustration.

Abstract
Fagaceae is a family of flowering plants widely distributed in the Northern Hemisphere, including deciduous and evergreen trees and shrubs. Species of Pestalotiopsis are well-known agents of leaf spot diseases, but targeted sampling on Fagaceae is still missing. To determine the diversity of Pestalotiopsis species associated with Fagaceae leaf spot in China, investigations were conducted in the main areas of Fagaceae distribution from 2016 to 2021. Diseased leaf tissues were collected, and fungal isolates were obtained from leaf spots. In the present study, 43 isolates of Pestalotiopsis were studied based on combined morphology and phylogeny. As a result, 10 new species were identified, viz., Pestalotiopsis anhuiensis, P. castanopsidis, P. changjiangensis, P. cyclobalanopsidis, P. foliicola, P. guangxiensis, P. guizhouensis, P. lithocarpi, P. shaanxiensis, and P. silvicola, and six new host records were recognized. IMPORTANCE Pestalotiopsis is a common fungal genus inhabiting plant tissues as endophytes, pathogens, and saprophytes. Fagaceae is a plant family including many important tree species, such as Castanea mollissima and Quercus spp. In this study, diseased leaves of Fagaceae in China were investigated, and 16 Pestalotiopsis species were identified based on morphology and phylogeny of combined loci of internal transcribed spacers (ITS), the translation elongation factor 1-α (tef1), and the beta-tubulin (tub2) genes. Among these, 10 new species were found, and six new host records were revealed. Our study significantly updates the taxonomy of Pestalotiopsis and enhances our understanding of leaf diseases of Fagaceae hosts.

Abstract
Rosa (Rosaceae) is an important ornamental and medicinal plant genus worldwide, with several species being cultivated in China. Members of Sporocadaceae (pestalotioid fungi) are globally distributed and include endophytes, saprobes but also plant pathogens, infecting a broad range of host plants on which they can cause important plant diseases. Although several Sporocadaceae species were recorded to inhabit Rosa spp., the taxa occurring on Rosa remain largely unresolved. In this study, a total of 295 diseased samples were collected from branches, fruits, leaves and spines of eight Rosa species (R. chinensis, R. helenae, R. laevigata, R. multiflora, R. omeiensis, R. rugosa, R. spinosissima and R. xanthina) in Gansu, Henan, Hunan, Qinghai, Shaanxi Provinces and the Ningxia Autonomous Region of China. Subsequently 126 strains were obtained and identified based on comparisons of DNA sequence data. Based on these results 15 species residing in six genera of Sporocadaceae were delineated, including four known species (Pestalotiopsis chamaeropis, Pes. rhodomyrtus, Sporocadus sorbi and Spo. trimorphus) and 11 new species described here as Monochaetia rosarum, Neopestalotiopsis concentrica, N. subepidermalis, Pestalotiopsis tumida, Seimatosporium centrale, Seim. gracile, Seim. nonappendiculatum, Seim. parvum, Seiridium rosae, Sporocadus brevis, and Spo. spiniger. This study also represents the first report of Pes. chamaeropis, Pes. rhodomyrtus and Spo. sorbi on Rosa. The overall data revealed that Pestalotiopsis was the most prevalent genus, followed by Seimatosporium, while Pes. chamaeropis and Pes. rhodomyrtus were the two most prevalent species. Analysis of Sporocadaceae abundance on Rosa species and plant organs revealed that spines of R. chinensis had the highest species diversity. Citation: Peng C, Crous PW, Jiang N, et al. 2022.

Characterization and identification of fungicide insensitive Pestalotiopsis-like species pathogenic to tea crop in India. World J Microbiol Biotechnol 2022; 39:34.

Abstract
Gray blight, a fungal disease caused by Pestalotiopsis-like species, is a widespread disease affecting tea crop (Camellia sinensis (L.) Kuntze) in many tea-growing countries, including India, resulting in huge losses in tea production. In India, several studies have been conducted to understand the fungal diseases of tea crop, but gray blight has not been well described in major tea growing areas such as in North Bengal, based on its geographic distribution, molecular analysis, or pathogenicity, and even fungicide resistance. The objective of this study was to identify and characterize the causative agents of gray blight disease in symptomatic leaf sample of tea crop collected from 27 tea gardens located in North Bengal, India and to evaluate some common fungicides against them in order to understand the resistance mechanism. In this study, we characterized Pestalotiopsis-like species based on the phylogenies of DNA sequences (internal transcribed spacers) and assessment of conidial characteristics. The study revealed that out of 27 isolates of gray blight pathogens, 17 belonged to the genus Pseudopestalotiopsis (Ps.), six isolates were Neopestalotiopsis, and four were Pestalotiopsis. Two novel species, Ps. thailandica and N. natalensis were introduced through this study. The most frequently isolated genus from C. chinensis was Pseudopestalotiopsis. Pathogenicity tests showed that the isolates displayed significantly different virulence when inoculated onto wounded tea leaves and the mycelial growth rate was positively correlated with pathogenicity (P < 0.01). Based on the 13 ISSR (Inter Simple Sequence Repeat) markers used and principal coordinate analysis, it was found that isolates were very diverse. Out of 27 isolates, IND0P2, DLG0P10, and BHAT0P11 isolates were insensitive against both MBC + M3 (Carbendazim + Mancozeb) and DMI (Hexaconazole) fungicides, while isolates SANY0P18, PAHG0P19, RANG0P24, and SING0P25 were insensitive only against MBC + M3 fungicide. Further, these insensitive isolates were grouped into separate clusters by ISSR, indicating their distinctiveness. However, all the evaluated isolates were susceptible to M1 (copper oxychloride) and another DMI (propiconazole) fungicides. Therefore, to manage gray blight, fungicide resistance management strategies as recommended by Fungicide Resistance Action Committee should be implemented.

Abstract
European blueberry is a common plant in coniferous and mixed forests that grows in Russia, Northern Europe, Asia, United States, and Canada. Among the fungi that cause blueberry diseases, the most harmful are Diaporthe vaccinii and Colletotrichum acutatum. These fungi are included in the consolidated list of quarantine objects of the Eurasian Economic Union and their occurrence and spread in the territory of countries of this Union is subject to strict control. Most taxa of micromycetes, particularly, Diaporthe and Colletotrichum species, can be correctly identified to the species level based on solely molecular phylogenetic features. The aim of the present work was to assess the biodiversity of fungi associated with blueberry growing in North-Western Russia and in Finland using morphological and molecular genetic features. Altogether, the study included 17 specimens of wild blueberry exhibiting necrotic spots on leaves and stem lesions that were collected in 2017 in St. Petersburg and in five districts of Leningrad region, as well as in the Republic of Karelia and in Finland. Analysis of the morphological and molecular genetic features of the fungal strains isolated from these blueberry specimens led to identification of 11 species: Boeremia exigua, Colletotrichum salicis, Diaporthe eres, Fusarium avenaceum, F. incarnatum, F. sporotrichioides, Heterophoma sylvatica, Kalmusia longispora, Microsphaeropsis olivacea, Neocucurbitaria cava, and Sporocadus rosigena. There were also fungi representing two sections of the genus Alternaria: Alternaria and Infectoriae, and micromycetes of the genera Chaetomium, Cladosporium, Coniothyrium, Curvularia, Epicoccum, Penicillium, Pestalotiopsis, Sordaria, and Trichoderma. The species Colletotrichum salicis, Heterophoma sylvatica, Kalmusia longispora, Microsphaeropsis olivacea, and Neocucurbitaria cava were for the first time found in Russia. The species Sporocadus rosigena was for the first time detected in Finland. Fusarium avenaceum, F. incarnatum, and F. sporotrichioides were for the first time observed in association with blueberry plants. The species Diaporthe vaccinii and Colletotrichum acutatum included in the consolidated list of quarantine objects of the Eurasian Economic Union were not detected in this study.

[PMID: 36354942 PMCID: PMC9696782 DOI: 10.3390/jof8111175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 10/25/2022] [Accepted: 11/02/2022] [Indexed: 11/09/2022] Open
Abstract
Pestalotiod fungi are associated with a wide variety of plants worldwide and occur as endophytes, pathogens, and saprobes. The present study provides an updated phylogeny for genera Neopestalotiopsis, Pestalotiopsis, and Seiridium using fresh collections from woody oil plants (Camellia oleifera, Olea europaea, Paeonia suffruticosa, Sapium sebiferum, and Vernicia fordii) in Sichuan Province, China. We coupled morphology and combined sequence data analyses of ITS, tub2, and tef1-α for Neopestalotiopsis and Pestalotiopsis, with ITS, LSU, tub2, tef1-α, and rpb2 for Seiridium. Three novel species of Neopestalotiopsis (N. mianyangensis, N. paeonia-suffruticosa, N. terricola) and three of Seiridium (S. guangyuanum, S. vernicola, S. oleae), were found. Three other species, Pestalotiopsis kenyana, Seiridium ceratosporum, and S. rosarum were identified and reported as new records. All isolated species are fully described and illustrated. Additionally, the sexual morph of Pestalotiopsis kenyana is described for the first time. Pathogenicity tests revealed that Neopestalotiopsis mianyangensis, N. paeonia-suffruticosa, N. terricola, Pestalotiopsis kenyana, Seiridium guangyuanum, S. vernicola, and S. oleae are pathogenic on detached olive leaves.

Abstract
Rhododendron is an essential ornamental plant that is abundant in Yunnan province. In Cangshan Mountain, Yunnan, China, 61 species of Rhododendron have been reported. Endophytic fungi are internal plant tissue inhabitants that do not harm the host. It has emerged as an exciting research topic as they have the potential to provide numerous secondary metabolites. This study is focused on taxonomic novelties and new host records of endophytic fungi associated with Rhododendron plants collected from Cangshan Mountain in Yunnan Province, China. Pestalotiopsis fungi are associated with a vast array of plant species worldwide. In this study, fresh leaves of Rhododendron cyanocarpum, Rhododendron decorum, and Rhododendron delavayi were collected from Cangshan Mountain, Yunnan Province, China. Endophytic Pestalotiopsis fungi associated with Rhododendron were characterized based on phylogenetic analyses of combined ITS, TEF1-α, and TUB genes along with morphological characteristics. Six new species (Pestalotiopsis appendiculata, Pestalotiopsis cangshanensis, Pestalotiopsis daliensis, Pestalotiopsis fusoidea, Pestalotiopsis rosarioides, and Pestalotiopsis suae) and a new host record (Pestalotiopsis trachicarpicola) are described. Detailed descriptions and color photo plates of these species are provided. It is the first time that the endophytic fungi of Rhododendron plants in Cangshan Mountain have been studied.

PLANTS (BASEL, SWITZERLAND) 2022; 11:2733. [PMID: 36297757 PMCID: PMC9608602 DOI: 10.3390/plants11202733] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 10/02/2022] [Accepted: 10/11/2022] [Indexed: 06/16/2023]
Abstract
Besides well-known grapevine trunk disease (GTD)-related pathogens, there is an increased interest in wood-colonizing fungi that infect grapevines. During 2017-2018, a survey was conducted in Cyprus and wood samples were collected from vines exhibiting typical GTD symptoms. Based on morphological and multilocus phylogenetic analyses (ITS, LSU, bt2, tef1-a), four species in the Sporocadaceae family were described and typified; two in the genus of Seimatosporium: Seim. cyprium sp. nov. and Seim. vitis-viniferae and two in Sporocadus: Spo. kurdistanicus and Spo. rosigena. The teleomorph of Seim. cyprium sp. nov. was also described. Pathogenicity trials with representative isolates of each species were performed on woody stems of two-year-old potted grapevines for 12 months under field conditions. All isolates were pathogenic, causing dark brown to black vascular discoloration, extending upward and downward from the inoculation point. Sporocadus isolates were significantly more aggressive than Seimatosporium with lesion lengths ranging from 9.24 to 6.90 and 4.13 to 4.00 cm, respectively. Successful re-isolations were also evident for all species and isolates. Seim. cyprium sp. nov. is a newly described species, while Spo. kurdistanicus and Spo. rosigena are reported for the first time in Europe on Vitis vinifera, suggesting the potential role of Sporocadaceae in the GTDs complex.

Fungal species associated with grapevine trunk diseases in Washington wine grapes and California table grapes, with novelties in the genera Cadophora, Cytospora, and Sporocadus. FRONTIERS IN FUNGAL BIOLOGY 2022; 3:1018140. [PMID: 37746176 PMCID: PMC10512239 DOI: 10.3389/ffunb.2022.1018140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 09/09/2022] [Indexed: 09/26/2023]
Abstract
Grapevine trunk diseases cause serious economic losses to grape growers worldwide. The identification of the causal fungi is critical to implementing appropriate management strategies. Through a culture-based approach, we identified the fungal species composition associated with symptomatic grapevines from wine grapes in southeastern Washington and table grapes in the southern San Joaquin Valley of California, two regions with contrasting winter climates. Species were confirmed through molecular identification, sequencing two to six gene regions per isolate. Multilocus phylogenetic analyses were used to identify novel species. We identified 36 species from 112 isolates, with a combination of species that are new to science, are known causal fungi of grapevine trunk diseases, or are known causal fungi of diseases of other woody plants. The novel species Cadophora columbiana, Cytospora macropycnidia, Cytospora yakimana, and Sporocadus incarnatus are formally described and introduced, six species are newly reported from North America, and grape is reported as a new host for three species. Six species were shared between the two regions: Cytospora viticola, Diatrype stigma, Diplodia seriata, Kalmusia variispora, Phaeoacremonium minimum, and Phaeomoniella chlamydospora. Dominating the fungal community in Washington wine grape vineyards were species in the fungal families Diatrypaceae, Cytosporaceae and Sporocadaceae, whereas in California table grape vineyards, the dominant species were in the families Diatrypaceae, Togniniaceae, Phaeomoniellaceae and Hymenochaetaceae. Pathogenicity tests demonstrated that 10 isolates caused wood discoloration similar to symptomatic wood from which they were originally isolated. Growth rates at temperatures from 5 to 35°C of 10 isolates per region, suggest that adaptation to local climate might explain their distribution.

Abstract
In the present study, we report two new asexual fungal species (i.e., Discosia rhododendricola, Neopestalotiopsis rhododendricola (Sporocadaceae) and a new host for a previously described species (i.e., Diaporthe nobilis; Diaporthaceae). All species were isolated from Rhododendron spp. in Kunming, Yunnan Province, China. All taxa are described based on morphology, and phylogenetic relationships were inferred using a multigenic approach (LSU, ITS, RPB2, TEF1 and TUB2). The phylogenetic analyses indicated that D. rhododendronicola sp. nov. is phylogenetically related to D. muscicola, and N. rhododendricola sp. nov is related to N. sonnaratae. Diaporthe nobilis is reported herein as a new host record from Rhododendron sp. for China, and its phylogeny is depicted based on ITS, TEF1 and TUB2 sequence data.

Abstract
In the present work, an epitype for Sphaeriaapiospora, the basionym of the type species of the genus Apiospora, Apiosporamontagnei, is selected among collections growing in the host plant species reported in the original protologue, Arundomicrantha. Most samples obtained from localities near that of the lectotype (Perpignan, France) belong to the same species, which is not significantly different from the clade previously named Ap.phragmitis, suggesting that this name is a later synonym of Ap.montagnei. In addition, the name Ap.marianiae is here proposed to accommodate a newly discovered species found in the Balearic Islands (Spain), and the asexual state of Ap.sichuanensis is described for the first time from samples growing in the same islands.

Abstract
Species of Arthrinium s. l. are usually known as endophytes, pathogens or saprobes occurring on various hosts and substrates and are characterised by globose to subglobose, sometimes irregular, dark brown and smooth-walled or finely verruculose conidia, always with a truncate basal scar. Currently, Arthrinium s. l. contains two phylogenetically distinct clades, namely, Apiospora and Arthrinium s. s. However, Arthriniumtrachycarpi and Ar.urticae have still not been properly classified. With new isolates from diseased leaves of Lithocarpusglaber collected in China, we propose the new Arthrinium-like genus Neoarthrinium in Amphisphaeriales. Based on the morphology and phylogeny of multiple loci, the new genus is established with the type species, N.lithocarpicola and three new combinations, N.moseri (syn. Wardomycesmoseri), N.trachycarpi (syn. Ar.trachycarpi) and N.urticae (syn. Ar.urticae) are added to this genus.

Abstract
Gray blight disease occurs widely in major tea-producing areas and harms the leaves of tea trees, which affects the quality and yield of processed tea. According to an analysis of previous sequencing data, miR319a may be important in the resistance of tea plants to gray blight disease. In this study, based on 5'RLM-RACE, qRT-PCR, sODN, CIN and transient transformation experiments in tobacco, CsTCP10 and CsTCP4 were found to be cleaved by miR319a. qRT-PCR and northern blotting also revealed that the expression pattern of CsTCP10 in tea leaves was opposite to that of miR319a, while that of CsTCP4 displayed no similar change. Furthermore, a large amount of reactive oxygen species was found to accumulate in tea leaves in the antisense oligodeoxynucleotide experiment, while the expression of CsTCP10 was inhibited. These results suggest that CsTCP10 is a positive regulator of the resistance of tea plants to gray blight disease. Compared with the wild-type, the expression of AtTCP10 in transgenic Arabidopsis plants was downregulated. After infection with the pathogen, the transgenic plants were more severely damaged. Our results suggest that miR319a facilitates Pestalotiopsis infection by suppressing the expression of CsTCP10 in tea plants.

Morphological studies of our new collections and the herbarium specimen of Arecophila gulubiicola (generic type) were conducted and the morphological affinity of our new collections with Arecophila was confirmed. Maximum likelihood and Bayesian analyses using combined ITS, LSU, rpb2 and β-tubulin data from our collections revealed the phylogeny of Cainiaceae. The monospecific genus Alishanica (type species Al. miscanthi), which had been accepted in Cainiaceae, is revisited and synonymised under Arecophila. Based on morphology and phylogeny, Arecophila australis sp. nov. and A. clypeata sp. nov. are introduced as new species, while A. miscanthi is a new record for China. All the new collections are illustrated and described.

Abstract
Although Apiospora Sacc. has previously been considered a sexual morph of Arthrinium species on the basis of phylogenetic, morphological, and ecological diagnoses, a recent study delimited these as different species. Recently, 14 species, including eight new species, of marine Arthrinium have been reported from Korea. Six known species have previously been renamed as species in the genus Apiospora (A. arundinis, A. marii, A. piptatheri, A. rasikravindrae, A. sacchari, and A. saccharicola). However, the eight new species of marine Arthrinium (Ar. agari, Ar. arctoscopi, Ar. fermenti, Ar. koreanum, Ar. marinum, Ar. pusillispermum, Ar. sargassi, and Ar. taeanense) are yet to be studied, and thus the taxonomic status of these species remains to be clarified. In this study, we conducted phylogenetic analyses using the internal transcribed spacer, 28S large subunit ribosomal RNA gene, translation elongation factor 1-alpha, and beta-tubulin regions to confirm the phylogenetic position of these eight species. Based on these analyses, we re-identified the eight Arthrinium species as new combinations in Apiospora. Additionally, among the six known Apiospora species, two (A. piptatheri and A. rasikravindrae) have not previously been recorded in Korea. On the basis of morphological and molecular analyses, we report these as new species in Korea. Herein, we present scanning electron micrographs detailing the morphologies of these species, along with phylogenetic trees and detailed descriptions.

Olive Fungal Epiphytic Communities are Affected by Their Maturation Stage. Microorganisms 2022; 10:microorganisms10020376. [PMID: 35208831 PMCID: PMC8879224 DOI: 10.3390/microorganisms10020376] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 01/29/2022] [Accepted: 02/03/2022] [Indexed: 02/04/2023] Open
Abstract
The phyllosphere comprises the aerial parts of plants and is colonized by a great diversity of microorganisms, either growing inside (as endophytes) or on the surface (as epiphytes) of plant tissues. The factors that structure the diversity of epiphytes and the importance of these microorganisms for host plant protection have been less studied when compared to the case of endophytes. In this work, the epiphytic fungal communities from fruits of the olive tree (olives) in different maturation stages (green and semi-ripened), obtained from different olive orchard managements (integrated and organic production) and from distinct cultivars displaying different susceptibilities to olive anthracnose (Cobrançosa and Madural), are compared by using a metabarcoding approach. We discuss whether such differences in host resistance against anthracnose depend on both the fungal taxa or fungal community composition. A total of 1565 amplicon sequence variants (ASVs) were obtained, mainly belonging to the Ascomycota phylum and Saccharomycetes class. Although significant differences on epiphytic fungal richness were observed among olives obtained in different production systems and maturation stages, these factors in addition to host cultivar did not influence the composition of the epiphytes. Despite these results, a co-inertia analysis showed that Aureobasidium spp. and Sporocadaceae spp. were positively associated with the green olives of the cv. Madural produced under integrated production, while Saccharomycetales spp. (Kluyveromyces, Candida, Kazachstania and Saccharomyces) were positively associated with the semi-ripened olives of the cv. Cobrançosa obtained from organic production. The discriminant power of these fungi, some of them recognized as biocontrol agents, suggest that they might be important in conferring differences on host plant susceptibility to anthracnose.

Abstract
Pinus sylvestris var. mongolica Litv. (Pinales: Pinaceae) is an excellent tree for soil and water conservation in Northeast China. The Honghua'erji area in Inner Mongolia is the "hometown of P. sylvestris var. mongolica", however, in recent years, coniferous diseases of P. sylvestris var. mongolica have frequently occurred here. During the investigation, it was found that some black spot needle blight had been observed in addition to the common blight caused by Sphaeropsis sapinea. From May to September 2020, black spot needle blight was found on hundreds of P. sylvestris var. mongolica trees in four forest farms, and the infection rate among the forests was 24.58 % (n=240). This disease first appeared on the upper part of the needles, and the needles then became withered and gradually showed light black spots, although they remained green. As the disease progressed, the needles eventually died and turned gray with many dark black spots. Fungal isolate named YJ-1 was obtained from infected needles of symptomatic pine trees, and a voucher specimen was deposited in Heilongjiang Province Key Laboratory of Forest Protection. Microscopic observation showed the conidia were 3-septate (4 cells) clavate spindles that measured 23.9 μm (20.8-25.9) × 5.9 μm (4.5-8.2) (n=50). The middle two cells were dark brown, and the septa were darker than the cells. Both apical and basal cells were hyaline. The apical cell had 2-4 appendages (mostly 3), and the basal cell had a truncate base (n=50). The cultural characteristics on potato dextrose agar medium were flat off-white and dense in 3-5 d. At approximately 5-7 d, the reverse side of the colony turned pale to slightly luteous. Superficial black acervuli were distributed in the center of the mature colonies after 10 d. Morphological, cultural and microscopic characteristics observed were similar of Heterotruncatella spartii (basionym: Truncatella spartii) reported by Hlaiem et al (2019). To further identify, total DNA was extracted and the internal transcribed spacer region (ITS-rDNA) was amplified by PCR using the primers ITS1/ITS4 and sequenced for BLASTn analysis and phylogenetic tree construction. The resulting 564 bp sequence (GenBank Accession No. OL662864) had 99.24% (521/525) to H. spartii MFLUCC 15-0537, with bootstrap support of at least 94% using the Neighbor-Joining algorithm by MEGA-X (Felsenstein, 1985). The fungus was identified as H. spartii based on morphology and molecular methods. A pathogenicity test was conducted by preparing a conidial suspension of 2.0 × 107 conidia/mL. The suspension was sprayed onto the needles of 20 pots of annual P. sylvestris ar. mongolica seedlings, and the control was sprayed with sterile water. Then the seedlings were placed in a constant temperature room at 25 °C. After 30 d, typical symptoms appeared on 11 inoculated needles, while the control needles remained symptomless. After 50 d, the re-isolation infection rate reached 66.7 %. The fungus present on the inoculated seedlings was morphologically identical to that originally observed on diseased pines, fulfilling Koch's postulates. The fungus was isolated from Spartium junceum for the first time and designated Truncatella spartii (Senanayake et al, 2015). It was then renamed H. spartii (Liu et al, 2019) and has been reported to infect P. pinea in Tunisia (Hlaiem et al, 2019). To our knowledge, this is the first report of H. spartii causing black spot needle blight on P. sylvestris var. mongolica in China and worldwide.

Abstract
The Iodosphaeriaceae is represented by the single genus, Iodosphaeria, which is composed of nine species with superficial, black, globose ascomata covered with long, flexuous, brown hairs projecting from the ascomata in a stellate fashion, unitunicate asci with an amyloid apical ring or ring lacking and ellipsoidal, ellipsoidal-fusiform or allantoid, hyaline, aseptate ascospores. Members of Iodosphaeria are infrequently found worldwide as saprobes on various hosts and a wide range of substrates. Only three species have been sequenced and included in phylogenetic analyses, but the type species, I. phyllophila, lacks sequence data. In order to stabilize the placement of the genus and family, an epitype for the type species was designated after obtaining ITS sequence data and conducting maximum likelihood and Bayesian phylogenetic analyses. Iodosphaeria foliicola occurring on overwintered Alnus sp. leaves is described as new. Five species in the genus form a well-supported monophyletic group, sister to the Pseudosporidesmiaceae in the Xylariales. Selenosporella-like and/or ceratosporium-like synasexual morphs were experimentally verified or found associated with ascomata of seven of the nine accepted species in the genus. Taxa included and excluded from Iodosphaeria are discussed.

Abstract
During a survey of plant-inhabiting fungi and water niches from Korea, noteworthy fungi were collected; among them, two new species, Paracamarosporium noviaquum sp. nov. and Phyllosticta gwangjuensis sp. nov., are described based on morphology and multi-gene phylogenies. Paracamarosporium noviaquum was characterized by its production of 1-celled and 2-celled conidia, forming conidiomata on only potato dextrose agar medium. Phyllosticta gwangjuensis was characterized by conidia hyaline, ovoid to ellipsoid shape, rounded at both ends, containing numerous guttulae or with a single large central guttule. Additional species were identified as Cosmospora lavitskiae, Monochaetia cameliae, and Roussoella doimaesalongensis, which are reported as new record species from Korea. Detailed descriptions and illustrations of these taxa are provided herein.

Abstract
Tea-oil tree (Camellia oleifera) is an important edible oil woody plant with a planting area of over 3,800,000 hectares in southern China. Pestalotioid fungi are associated with a wide variety of plants worldwide along with endophytes, pathogens, and saprobes. In this study, symptomatic leaves of C. oleifera were collected from Guangdong, Guangxi, Hainan, Hunan, and Jiangsu Provinces and pestalotioid fungi are characterized based on combined sequence data analyses of internal transcribed spacer (ITS), beta tubulin (tub2), and translation elongation factor 1-alpha (tef-1α) coupled with morphological characteristics. As a result, seven species were confirmed, of which five species are described as new viz. N. camelliae-oleiferae, P. camelliae-oleiferae, P. hunanensis, P. nanjingensis, P.nanningensis, while the other two are reported as known species, viz., N. cubana and N. iberica. Pathogenicity assays showed that all species except for P. nanjingensis developed brown lesions on healthy leaves and P. camelliae-oleiferae showed stronger virulence.

Abstract
In the present study six species of Arthrinium (including a new taxon, Ar. crenatum) are described and subjected to phylogenetic analysis. The analysis of ITS and 28S rDNA, as well as sequences of tef1 and tub2 exons suggests that Arthrinium s. str. and Apiospora represent independent lineages within Apiosporaceae. Morphologically, Arthrinium and Apiospora do not seem to have clear diagnostic features, although species of Arthrinium often produce variously shaped conidia (navicular, fusoid, curved, polygonal, rounded), while most species of Apiospora have rounded (face view) / lenticular (side view) conidia. Ecologically, most sequenced collections of Arthrinium were found on Cyperaceae or Juncaceae in temperate, cold or alpine habitats, while those of Apiospora were collected mainly on Poaceae (but also many other plant host families) in a wide range of habitats, including tropical and subtropical regions. A lectotype for Sphaeria apiospora (syn.: Ap. montagnei, type species of Apiospora) is selected among the original collections preserved at the PC fungarium, and the putative identity of this taxon, found on Poaceae in Mediterranean lowland habitats, is discussed. Fifty-five species of Arthrinium are combined to Apiospora, and a key to species of Arthrinium s. str. is provided. Citation: Pintos Á, Alvarado P (2021).

Abstract
Several fungal trunk pathogens are associated with olive trunk diseases in South Africa. Little is known regarding the inoculum sources of these pathogens in the olive industry, and no specific management strategies are in place. The aim of this study was to investigate the status of olive nurseries in South Africa, with regard to the presence of trunk pathogens in olive plant material, to determine whether nursery material can be considered inoculum sources contributing to long-distance dispersal of these pathogens. Isolations were made from asymptomatic cuttings from mother blocks (stage 1), asymptomatic and symptomatic rooted cuttings (stage 2), and 1- to 2-year-old trees (stage 3) of eight cultivars in two nurseries. Known olive trunk pathogens of Nectriaceae, Diaporthaceae, Botrysphaeriaceae, Togniniaceae, Phaeomoniellaceae, and Pleurostomataceae were recovered. Neofusicoccum australe was detected in a single stage 1 cutting. Stage 3 material showed the highest incidence of fungi from these families, with Pleurostoma richardsiae having the highest incidence in both nurseries (82.2 and 36.7% of the 1- to 2-year-old trees). Phaeoacremonium parasiticum was present in 28.9% of the trees from one nursery (stage 3). The remaining pathogens occurred in ≤13.3% of the material. These results indicate that nursery propagation material from mother blocks harbors low levels of trunk pathogens and that additional infections occur during the nursery process. Management strategies should focus on the prevention and elimination of infections in mother blocks as well as during the propagation process to ensure that pathogen-free material is delivered to producers.

Abstract
During our investigation of palm fungi in Thailand, two interesting taxa from Elaeis guineensis and Metroxylon sagu (Arecaceae) were collected. Based on phylogenetic analyses of a combined dataset of ITS, LSU, rpb2, and tub2 nucleotide sequences as well as unique morphological characteristics, we introduce the new genus Haploanthostomella within Xylariales, and a new species Endocalyx metroxyli. Additionally, in our study, the genus Endocalyx is transferred to the family Cainiaceae based on its brown conidia and molecular phylogenetic evidence.

Abstract
Collections of fungal samples from two dead leaf specimens from Italy were subjected to morphological examination and phylogenetic analyses. Two coelomycetous taxa belonging to two different genera in Xylariomycetidae, Sordariomycetes, namely Discosia and Sporocadus, were identified. The Discosia taxon is revealed as a new species and is herein introduced as Discosia ravennica sp. nov. while the Sporocadus taxon is identified as Sporocadus rosigena. Multi-locus phylogeny based on DNA sequence data of the large subunit (LSU) and internal transcribed spacer (ITS) of nuclear ribosomal genes, β-tubulin (β-tub) and RNA polymerase II second largest subunit (rpb2) showed that D. ravennica is related to D. neofraxinea but it forms an independent lineage that supports its new species status. The new taxon also differs from other Discosia species by its unilocular to bilocular, superficial and applanate conidiomata with basal stroma composed of cells of textura angularis, elongate-ampulliform conidiogenous cells and conidia smaller in size. Sporocadus rosigena is here reported as a new host record from Quercus ilex from Italy. Descriptions, illustrations and molecular data for both species are provided in this paper.

Phylogeny, Global Biogeography and Pleomorphism of Zanclospora. Microorganisms 2021; 9:microorganisms9040706.

Abstract
Zanclospora (Chaetosphaeriaceae) is a neglected, phialidic dematiaceous hyphomycete with striking phenotypic heterogeneity among its species. Little is known about its global biogeography due to its extreme scarcity and lack of records verified by molecular data. Phylogenetic analyses of six nuclear loci, supported by phenotypic data, revealed Zanclospora as highly polyphyletic, with species distributed among three distantly related lineages in Sordariomycetes. Zanclospora is a pleomorphic genus with multiple anamorphic stages, of which phaeostalagmus-like and stanjehughesia-like are newly discovered. The associated teleomorphs were previously classified in Chaetosphaeria. The generic concept is emended, and 17 species are accepted, 12 of which have been verified with DNA sequence data. Zanclospora thrives on decaying plant matter, but it also occurs in soil or as root endophytes. Its global diversity is inferred from metabarcoding data and published records based on field observations. Phylogenies of the environmental ITS1 and ITS2 sequences derived from soil, dead wood and root samples revealed seven and 15 phylotypes. The field records verified by DNA data indicate two main diversity centres in Australasia and Caribbean/Central America. In addition, environmental ITS data have shown that Southeast Asia represents a third hotspot of Zanclospora diversity. Our data confirm that Zanclospora is a rare genus.

Abstract
Dictyochaeta (Chaetosphaeriaceae) is a phialidic dematiaceous hyphomycete with teleomorphs classified in Chaetosphaeria. It is associated with significant variability of asexual morphological traits, which led to its broad delimitation. In the present study, six loci: nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS barcode), nuc 18S rDNA (18S), nuc 28S rDNA (28S), DNA-directed RNA polymerase II second largest subunit gene (RPB2), translation elongation factor 1-α (TEF1-α), and β-tubulin (TUB2), along with comparative morphological and cultivation studies, are used to reevaluate the concept of Dictyochaeta and establish species boundaries. Based on revised species, morphological characteristics of conidia (shape, septation, absence or presence of setulae), collarettes (shape), and setae (presence or absence) and an extension of the conidiogenous cell proved to be important at the generic level. The dual DNA barcoding using ITS and TEF1-α, together with TUB2, facilitated accurate identification of Dictyochaeta species. Thirteen species are accepted, of which seven are characterized in this study; an identification key is provided. It was revealed that D. fuegiana, the type species, is a complex of three distinct species including D. querna and the newly described D. stratosa. Besides, a new species, D. detriticola, and two new combinations, D. callimorpha and D. montana, are proposed. An epitype of D. montana is selected. Dictyochaeta includes saprobes on decaying wood, bark, woody fruits, and fallen leaves. Dictyochaeta is shown to be distantly related to the morphologically similar Codinaea, which is resolved as paraphyletic. Chaetosphaeria talbotii with a Dictyochaeta anamorph represents a novel lineage in the Chaetosphaeriaceae; it is segregated from Dictyochaeta, and a new genus Achrochaeta is proposed. Multigene phylogenetic analysis revealed that D. cylindrospora belongs to the Vermiculariopsiellales, and a new genus Tubulicolla is introduced.

Abstract
Camellia sinensis (L.) O. Kuntze, commonly known as tea, is widely cultivated around the world in tropical and subtropical areas. Tea is mainly manufactured using young shoots of tea plants. Therefore, it is essential to control foliar diseases. Gray blight disease is caused by pestalotiopsis-like taxa and is known as one of the most destructive tea diseases. Although several studies have provided the groundwork for the fungal diseases associated with C. sinensis in Taiwan, gray blight disease has not been characterized based on diversity, molecular systematics, or pathogenicity. The goal of this study was to identify and characterize the causative agents of tea gray blight disease. A total of 98 pestalotiopsis-like isolates associated with symptomatic leaves of C. sinensis from major tea fields in Taiwan were investigated. Based on phylogenies of single and concatenated DNA sequences (internal transcribed spacer, β-tubulin, translation elongation factor 1-α) together with morphology, we resolved most of the pestalotiopsis-like species in this study. The study revealed seven well-classified taxa and seven tentative clades in three genera: Pestalotiopsis, Pseudopestalotiopsis, and Neopestalotiopsis. One novel species, Pseudopestalotiopsis annellata, was introduced. Five new records, Pseudopestalotiopsis chinensis, Pseudopestalotiopsis camelliae-sinensis, Pestalotiopsis camelliae, Pestalotiopsis yanglingensis, and Pestalotiopsis trachicarpicola, were introduced for the first time in Taiwan. Pseudopestalotiopsis chinensis was the taxon most frequently isolated from C. sinensis in this study. Furthermore, results of pathogenicity assessments exhibited that, with wound inoculation, all assayed isolates in this study were pathogenic on tea leaves. Pseudopestalotiopsis chinensis and Pseudopestalotiopsis camelliae-sinensis were identified as the major pathogens associated with gray blight disease of tea in Taiwan. To our knowledge, this is the first study of the diversity, pathogenicity, and characterization of pestalotiopsis-like fungi causing tea gray blight disease in Taiwan.

Abstract
Two Castanea plant species, C. henryi and C. mollissima, are cultivated in China to produce chestnut crops. Leaf spot diseases commonly occur in Castanea plantations, however, little is known about the fungal species associated with chestnut leaf spots. In this study, leaf samples of C. henryi and C. mollissima were collected from Beijing, Guizhou, Hunan, Sichuan and Yunnan Provinces, and leaf-inhabiting fungi were identified based on morphology and phylogeny. As a result, twenty-six fungal species were confirmed, including one new family, one new genus, and five new species. The new taxa are Pyrisporaceae fam. nov., Pyrispora gen. nov., Aureobasidium castaneae sp. nov., Discosia castaneae sp. nov., Monochaetia castaneae sp. nov., Neopestalotiopsis sichuanensis sp. nov. and Pyrispora castaneae sp. nov.
