Abstract
The current study was aimed to introduce five new species of Cordyceps from Yunnan, with morphological descriptions, illustrations, color photographs, phylogenetic placement, associated host, and a comparison with allied taxa. The five new species were morphologically distinct from all other Cordyceps sensu lato species, and it was also suggested that they should differ from other species in the genus Cordyceps based on combined multigene analyses. Employing DNA nucleotide sequences of the nrLSU, nrSSU, tef-1α, rpb1, and rpb2, the five new species were recognized in the clade of Cordyceps by using molecular phylogenetic analyses, including five well-supported subclades: three new species, Cordyceps bullispora, Cordyceps longiphialis, and Cordyceps nabanheensis, were found in the subclade of C. pruinosa, and two new species, Cordyceps pseudotenuipes and Cordyceps simaoensis, were located in the subclade of C. tenuipes. The five novel species shared similar morphologies to other species in the genus Cordyceps, with fleshy and brightly pigmented stromata; perithecia superficial to completely immersed, ordinal in arrangement; and hyaline asci, with thickened cylindrical ascus apex. The morphological characteristics of 66 species in Cordyceps sensu stricto, namely, 5 novel species and 61 known taxa, were also compared.

Abstract
Leaf spot is a serious disease in the growth and development of muskmelon, which can affect its quality and yield. Over the past years, Malianzhuang Muskmelon Base, the main muskmelon producing area in Shandong Province, China, has been seriously affected by leaf spot. Since 2018, symptomatic leaves were collected from 11 production areas of this base to determine the pathogens of muskmelon foliar diseases. Two-hundred fungal strains were isolated and 10 genera and 17 species were identified based on morphological characteristics and multilocus phylogenetic analysis (ITS, GADPH, RPB2, HIS3, EF-1α, and LSU). The most frequently isolated species from each sampling area was Alternaria tenuissima with 77 strains, followed by A. alternata. Pathogenicity experiments showed that A. alternata, A. tenuissima, Fusarium neocosmosporiellum (formerly Neocosmospora vasinfecta), F. acuminatum, Exserohilum rostratum, Bipolaris sorokiniana, and Stagonosporopsis cucurbitacearum (formerly Didymella bryoniae) could cause symptoms highly similar to those of infected leaves observed under natural conditions in the field. Therefore, these fungal isolates are considered to be the primary pathogens causing muskmelon leaf spot, and A. tenuissima and A. alternata were the most common and virulent pathogens in this study. In addition, this is the first study of F. neocosmosporiellum, F. acuminatum, E. rostratum, and B. sorokiniana as pathogens associated to muskmelon leaf spot in China as well as the world.

Morphology and molecular study of three new Cordycipitoid fungi and its related species collected from Jilin Province, northeast China. MycoKeys 2021; 83:161-180.

Abstract
Cordyceps species are notable medicinal fungi in China, which are pathogenic on insects and exhibit high biodiversity in tropical and subtropical regions. Recently, three new Cordyceps species, Cordycepschangchunensis and Cordycepsjingyuetanensis growing on pupae of Lepidoptera and Cordycepschangbaiensis growing on larvae of Lepidoptera, were found in Jilin Province, China and are described, based on morphological and ecological characteristics. These three new species are similar to the Cordycepsmilitaris group, but are distinctly distinguishable from the known species. Cordycepschangchunensis, characterised by its small and light yellow to orange stromata which is occasionally forked, covered with white mycelium at the base of stipe, globose to ovoid perithecia, is macroscopically similar to Cordycepsmilitaris. Cordycepschangbaiensis is clearly discriminated from other Cordyceps species by its white to orange and branched stromata, clavate to cylindrical fertile apical portion, immersed and globose to ovoid perithecia. Moreover, unbranched, clavate and orange to light red stromata, almond-shaped to ovoid and immersed perithecia separate Cordycepsjingyuetanensis from other Cordyceps species. nrITS, nrLSU and EF-1α sequences were undertaken and phylogenetic trees, based on Maximum Likelihood and Bayesian Inference analysis showed that the three new species clustered with Cordycepsmilitaris, but formed individual clades, as well as confirmed the results of our morphological study.

Identification and phylogenetic analysis of a collection of Beauveria spp. Isolates from Central America and Puerto Rico. J Invertebr Pathol 2021; 184:107642. [PMID: 34216626 DOI: 10.1016/j.jip.2021.107642] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 06/15/2021] [Accepted: 06/25/2021] [Indexed: 11/27/2022]
Abstract
The genus Beauveria comprises economically important entomopathogenic fungi, widely used for biological control in agriculture. Interest in these organisms in Costa Rica prompted surveys and establishment of collections in the past two decades. However, there was neither a formal identification nor a characterization of the isolates. With that purpose, the morphology and genetic variation by microsatellites and partial sequencing of Bloc, TEF-1α and RPB2 regions were studied for 32 isolates of Beauveria, which included 26 from Costa Rica, five from Puerto Rico and one from Honduras. The isolates were identified as B. bassiana (29) and B. caledonica (3). Ninety-three percent of B. bassiana isolates belonged to a monophyletic group of African and Neotropical isolates. A total of 105 alleles were recorded with 11 SSR markers, and the results suggested high diversity within the collection. Mantel tests showed low association between geographic origin and the variation among isolates.
