Abstract
Peatswamp forest is a unique habitat that supports high biodiversity, particularly fungal diversity. The current study collected submerged and dead plant parts from Eleiodoxaconferta, Eugeissonatristis and Licualapaludosa from a peatswamp forest in Narathiwat Province, Thailand. Morphological features coupled with multigene phylogenetic analyses of ITS, LSU, rpb2 and tef1-α sequence data identified our isolates as new Distoseptispora species (viz. D.arecacearumsp. nov., D.eleiodoxaesp. nov. and D.narathiwatensissp. nov.). Morphological descriptions, illustrations and notes are provided.

Pereira DS, Phillips AJL. Palm Fungi and Their Key Role in Biodiversity Surveys: A Review. J Fungi (Basel) 2023; 9:1121.

Abstract
Over the past three decades, a wealth of studies has shown that palm trees (Arecaceae) are a diverse habitat with intense fungal colonisation, making them an important substratum to explore fungal diversity. Palm trees are perennial, monocotyledonous plants mainly restricted to the tropics that include economically important crops and highly valued ornamental plants worldwide. The extensive research conducted in Southeast Asia and Australasia indicates that palm fungi are undoubtedly a taxonomically diverse assemblage from which a remarkable number of new species is continuously being reported. Despite this wealth of data, no recent comprehensive review on palm fungi exists to date. In this regard, we present here a historical account and discussion of the research on the palm fungi to reflect on their importance as a diverse and understudied assemblage. The taxonomic structure of palm fungi is also outlined, along with comments on the need for further studies to place them within modern DNA sequence-based classifications. Palm trees can be considered model plants for studying fungal biodiversity and, therefore, the key role of palm fungi in biodiversity surveys is discussed. The close association and intrinsic relationship between palm hosts and palm fungi, coupled with a high fungal diversity, suggest that the diversity of palm fungi is still far from being fully understood. The figures suggested in the literature for the diversity of palm fungi have been revisited and updated here. As a result, it is estimated that there are about 76,000 species of palm fungi worldwide, of which more than 2500 are currently known. This review emphasises that research on palm fungi may provide answers to a number of current fungal biodiversity challenges.

Abstract
The genus Thyridium, previously known as a saprobic or hemibiotrophic ascomycete on various plants, was revised taxonomically and phylogenetically. Sequences of the following six regions, that is, the nuclear ribosomal internal transcribed spacer (ITS) region, the large subunit (LSU) of rDNA, the second largest RNA polymerase II subunit (rpb2) gene, translation elongation factor 1-alpha (tef1) gene, the actin (act) gene, and the beta-tubulin (tub2) gene, were generated for molecular phylogenetic analyses of species of this genus. Phialemoniopsis, a genus encompassing medically important species, is synonymised with Thyridium based on molecular evidence and morphological similarities in their asexual characters. The generic concept for Thyridium is expanded to include species possessing both coelomycetous and hyphomycetous complex asexual morphs. In addition to type species of Thyridium, T.vestitum, nine species were accepted in Thyridium upon morphological comparison and molecular phylogenetic analyses in this study. All seven species of Phialemoniopsis were treated as members of the genus Thyridium and new combinations were proposed. A bambusicolous fungus, Pleosporapunctulata, was transferred to Thyridium, and an epitype is designated for this species. A new species, T.flavostromatum, was described from Phyllostachyspubescens. The family Phialemoniopsidaceae, proposed as a familial placement for Phialemoniopsis, was regarded as a synonym of Thyridiaceae. A new order, Thyridiales, was established to accommodate Thyridiaceae; it forms a well-supported, monophyletic clade in Sordariomycetes.

Abstract
Background Mendogia belongs to Dothideomycetes and its members are epiphytic on living bamboo culms or palms and distributed in tropical regions. Currently, the genus comprises seven species. Another collection resembling Mendogia was collected from the leaves of Fagales sp. in Thailand. Morphological characteristics and multilocus phylogenetic analyses, using ITS, LSU and SSU sequences, showed that the fungus is new to science, described herein as Mendogiadiffusa. Mendogiadiffusa is characterised by apothecial ascostromata, a carbonised epithecium, dark brown setae on the ascostromatal surface, hyaline paraphysoids, ovoid to clavate asci and oblong to elliptical, muriform ascospores. The fungus has a dark pigmented surface and is occasionally facultatively associated with patches of green algae, but not actually lichenised. Instead, the fungus penetrates the upper leaf surface, forming dark pigmented isodiametric cells below the epidermis. New information Re-examination of specimens of M.chiangraiensis, M.macrostroma and M.yunnanensis revealed the absence of algal associations. The status of Mendogiaphilippinensis (= M.calami) and M.bambusina (= Uleopeltisbambusina) was established, based on morphological comparisons and previous studies. Comprehensive morphological descriptions with phylogenetic analyses support M.diffusa as a novel species in Myriangiaceae. An updated key to the known species of the genus is also provided.

Abstract
Endophytic, saprobic, and pathogenic fungi have evolved elaborate strategies to obtain nutrients from plants. Among the diverse plant-fungi interactions, the most crucial event is the attachment and penetration of the plant surface. Appressoria, specialized infection structures, have been evolved to facilitate this purpose. In this review, we describe the diversity of these appressoria and classify them into two main groups: single-celled appressoria (proto-appressoria, hyaline appressoria, melanized (dark) appressoria) and compound appressoria. The ultrastructure of appressoria, their initiation, their formation, and their function in fungi are discussed. We reviewed the molecular mechanisms regulating the formation and function of appressoria, their strategies to evade host defenses, and the related genomics and transcriptomics. The current review provides a foundation for comprehensive studies regarding their evolution and diversity in different fungal groups.

Abstract
Palms (Arecaceae) are substrates for a highly diverse range of fungi. Many species are known as saprobes and many are important plant pathogens. Over the course of our studies of micro-fungi from palms in Thailand, two new taxa were discovered. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, SSU, and tef1-α sequence data revealed their taxonomic positions within Massarinaceae. There are currently ten genera identified and accepted in Massarinaceae, with the addition of the two new genera of Haplohelminthosporium and Helminthosporiella, that are introduced in this paper. Each new genus is provided with a full description and notes, and each new taxon is provided with an illustration for the holotype. A list of identified and accepted species of Helminthosporium with morphology, host information, locality, sequence data, and related references of Helminthosporium reported worldwide is provided based on records in Species Fungorum 2021. This work provides a micro-fungi database of Haplohelminthosporium, Helminthosporiella, and Helminthosporium which can be modified and validated as new data come to light.

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
The Chaetosphaeriaceae are a diverse group of pigmented, predominantly phialidic hyphomycetes comprised of several holomorphic genera including Chaetosphaeria, the most prominent genus of the family. Although the morphology of the teleomorphs of the majority of Chaetosphaeria is rather uniform, their associated anamorphs primarily exhibit the variability and evolutionary change observed in the genus. An exception from the morphological monotony among Chaetosphaeria species is a group characterised by scolecosporous, hyaline to light pink, multiseptate, asymmetrical ascospores and a unique three-layered ascomatal wall. Paragaeumannomyces sphaerocellularis, the type species of the genus, exhibits these morphological traits and is compared with similar Chaetosphaeria with craspedodidymum- and chloridium-like synanamorphs. Morphological comparison and phylogenetic analyses of the combined ITS-28S sequences of 35 isolates and vouchers with these characteristics revealed a strongly-supported, morphologically well-delimited clade in the Chaetosphaeriaceae containing 16 species. The generic name Paragaeumannomyces is applied to this monophyletic clade; eight new combinations and five new species, i.e. P. abietinus sp. nov., P. elegans sp. nov., P. granulatus sp. nov., P. sabinianus sp. nov. and P. smokiensis sp. nov., are proposed. A key to Paragaeumannomyces is provided. Using morphology, cultivation studies and phylogenetic analyses of ITS and 28S rDNA, two additional new species from freshwater and terrestrial habitats, Codinaea paniculata sp. nov. and Striatosphaeria castanea sp. nov., are described in the family. A codinaea-like anamorph of S. castanea forms conidia with setulae at each end in axenic culture; this feature expands the known morphology of Striatosphaeria. A chaetosphaeria-like teleomorph is experimentally linked to Dendrophoma cytisporoides, a sporodochial hyphomycete and type species of Dendrophoma, for the first time.

Abstract
In this paper, Claviformisporagen. nov. in Linocarpaceae is introduced from Phyllostachysheteroclada in Sichuan Province, China. The new genus is characterised by its distinct morphological characters, such as ostiole with periphyses, asci with a thick doughnut-shaped, J- apical ring and clavate ascospore without septum-like band and appendage. Maximum Likelihood and Bayesian Inference phylogenetic analyses, based on DNA sequence data from ITS, LSU, SSU and TEF-1α regions, provide further evidence that the fungus is a distinct genus within this family. The new genus is compared with similar genera, such as Linocarpon and Neolinocarpon. Descriptions, illustrations and notes are provided for the new taxon.

Abstract
Based on molecular phylogenetic and morphological evidence, the new genus Linosporopsis (Xylariales) is established for several species previously classified within Linospora (Diaporthales). Fresh collections of Linospora ischnotheca from dead overwintered leaves of Fagus sylvatica and of L. ochracea from dead overwintered leaves of Malus domestica, Pyrus communis, and Sorbus intermedia were isolated in pure culture, and molecular phylogenetic analyses of a multi-locus matrix of partial nuITS-LSU rDNA, RPB2 and TUB2 sequences as well as morphological investigations revealed that both species are unrelated to the diaporthalean genus Linospora, but belong to Xylariaceae sensu stricto. The new combinations Linosporopsis ischnotheca and L. ochracea are proposed, the species are described and illustrated, and their basionyms lecto- and epitypified. Linospora faginea is synonymized with L. ischnotheca. Based on similar morphology and ecology, Linospora carpini and Linospora magnagutiana from dead leaves of Carpinus betulus and Sorbus torminalis, respectively, are also combined in Linosporopsis. The four accepted species of Linosporopsis are illustrated, a key to species is provided and their ecology is discussed.

Abstract
Sordariomycetes is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi mainly characterized by perithecial ascomata and inoperculate unitunicate asci. Freshwater Sordariomycetes play an important role in ecosystems and some of them have the potential to produce bioactive compounds. This study documents and reviews the freshwater Sordariomycetes, which is one of the largest and important groups of fungi in aquatic habitats. Based on evidence from DNA sequence data and morphology, we introduce a new order Distoseptisporales, two new families, viz. Ceratosphaeriaceae and Triadelphiaceae, three new genera, viz. Aquafiliformis, Dematiosporium and Neospadicoides, 47 new species, viz. Acrodictys fluminicola, Aquafiliformis lignicola, Aquapteridospora fusiformis, Arthrinium aquaticum, Ascosacculus fusiformis, Atractospora aquatica, Barbatosphaeria lignicola, Ceratosphaeria aquatica, C. lignicola, Chaetosphaeria aquatica, Ch. catenulata, Ch. guttulata, Ch. submersa, Codinaea yunnanensis, Conioscypha aquatica, C. submersa, Cordana aquatica, C. lignicola, Cosmospora aquatica, Cylindrotrichum submersum, Dematiosporium aquaticum, Dictyochaeta cangshanensis, D. ellipsoidea, D. lignicola, D. submersa, Distoseptispora appendiculata, D. lignicola, D. neorostrata, D. obclavata, Hypoxylon lignicola, Lepteutypa aquatica, Myrmecridium aquaticum, Neospadicoides aquatica, N. lignicola, N. yunnanensis, Ophioceras submersum, Peroneutypa lignicola, Phaeoisaria filiformis, Pseudostanjehughesia lignicola, Rhodoveronaea aquatica, Seiridium aquaticum, Sporidesmiella aquatica, Sporidesmium lageniforme, S. lignicola, Tainosphaeria lunata, T. obclavata, Wongia aquatica, two new combinations, viz. Acrodictys aquatica, Cylindrotrichum aquaticum, and 9 new records, viz. Chaetomium globosum, Chaetosphaeria cubensis, Ch. myriocarpa, Cordana abramovii, Co. terrestris, Cuspidatispora xiphiago, Sporidesmiella hyalosperma, Stachybotrys chartarum,S. chlorohalonata. A comprehensive classification of the freshwater Sordariomycetes is presented based on updated literature.

Abstract
Palms represent the most morphological diverse monocotyledonous plants and support a vast array of fungi. Recent examinations of palmicolous fungi in Thailand led to the discovery of a group of morphologically similar and interesting taxa. A polyphasic approach based on morphology, multi-gene phylogenetic analyses and divergence time estimates supports the establishment of a novel pleosporalean family Striatiguttulaceae, which diversified approximately 39 (20–63) MYA (crown age) and 60 (35–91) MYA (stem age). Striatiguttulaceae is characterized by stromata or ascomata with a short to long neck, trabeculate pseudoparaphyses and fusiform to ellipsoidal, 1–3-septate ascospores, with longitudinal striations and paler end cells, surrounded by a mucilaginous sheath. Multi-gene phylogenetic analysis showed that taxa of Striatiguttulaceae form a well-supported and distinct monophyletic clade in Pleosporales, and related to Ligninsphaeriaceae and Pseudoastrosphaeriellaceae. However, these families can be morphologically demarcated by the slit-like ascomata and extremely large ascospores in Ligninsphaeriaceae and the rather narrow fusiform ascospores in Pseudoastrosphaeriellaceae. Eight strains of Striatiguttulaceae formed two monophyletic sub-clades, which can be recognized as Longicorpusgen. nov. and Striatiguttulagen. nov. Morphologically, the genus Longicorpus can be differentiated from Striatiguttula by its elongated immersed ascomata and fusiform ascospores with relatively larger middle cells and paler end cells. Two new species Striatiguttulanypae and S.phoenicis, and one new combination, Longicorpusstriataspora are introduced with morphological details, and phylogenetic relationships are discussed based on DNA sequence data.
