... Most Distoseptispora species are reported as saprophytes, typically found on decaying wood in terrestrial and freshwater habitats (Hyde et al. , 2019Su et al. 2016;Xia et al. 2017;Yang et al. 2018;Crous et al. 2019;Luo et al. 2019). The initial descriptions of Distoseptispora are derived from its asexual morphology (Hyde et al. , 2019Su et al. 2016;Yang et al. 2018Yang et al. , 2021Luo et al. 2019;Sun et al. 2020). ...
... Crane & Dumont) J.W. Xia & X.G. Zhang stands out due to its unique morphological characteristics, especially its oblate or subglobose conidia, distinguishing it from other species within Distoseptispora (Xia et al. 2017). The species was initially introduced as Acrodictys martinii J.L. Crane & Dumont by Crane and Dumont (1975) based on morphological characteristics. ...
... Then, it underwent several taxonomic revisions based solely on morphology (Baker et al. 2002;Delgado 2009). Later, Xia et al. (2017) reclassified Acrodictys martinii as D. martinii based on genetic analysis. However, the morphological traits of D. martinii greatly diverge from typical Distoseptispora features (Crane and Dumont 1975;Xia et al. 2017). ...
During our investigation of saprophytic fungi in Guizhou and Hainan provinces, China, three hyphomycetes were collected from terrestrial and freshwater habitats. Based on morphological characteristics and phylogenetic analyses of combined ITS, LSU, tef 1-α, and rpb 2 sequence data, two new species are introduced: Distoseptispora hainanensis and D. lanceolatispora . Additionally, one known species, D. tectonae , previously unreported from Edgeworthia chrysantha , is newly reported. Detailed descriptions, illustrations, and a phylogenetic tree to show the two new species and the new host record of Distoseptispora are provided. In addition, a checklist of Distoseptispora species with their locations, lifestyles, habitats, and hosts is provided.

During an ongoing investigation of bambusicolous fungi in Sichuan province, China, five hyphomycetous taxa were collected and recognized as members of Sordariomycetes. Based on morphological comparisons, culture characteristics, and the multi-locus phylogenetic analyses of combined SSU, ITS, LSU, rpb2 and tef1α sequence dataset, five species, viz. Conioscypha sichuanensis, Conlarium guizhouense, Rhexoacrodictys fimicola, R. melanospora, Wongia bambusae are identified. Conioscypha sichuanensis formed a sister lineage to Conio. bambusicola, which was also found from a bamboo host but can be distinguished from Conio. sichuanensis by different conidial shape. Wongia bambusae is characterized by unbranched, septate conidiophores and cylindric-fusiform conidia, and is most similar to W. ficherai. However, they are phylogenetically distinct. Conlarium guizhouense and R. melanospora, were recollected from the bamboo hosts in terrestrial habitats and reported as new host records in this study. Detailed descriptions and notes on the phylogenetic placement of these species are provided.
... The DNA amplification was performed by polymerase chain reaction (PCR) using the respective loci (ITS, SSU, LSU, TEF1, RPB2). Primer sets used for these genes were as follows: ITS: ITS5/ITS4 (White et al. 1990), SSU: 18S-F/18S-R, LSU: 28S1-F/28S3-R (Xia et al. 2017), TEF1: EF1-983F/EF1-2218R (Rehner 2001;Zhao et al. 2018) and RPB2: dRPB2-5f/dRPB2-7r (Voglmayr et al. 2016). The final volume of the PCR reaction was 25 μl, containing 1 μl of DNA template, 1 μl each of the forward and reverse primer, 12.5 μl of 2 × Power Taq PCR Master-Mix and 9.5 μl of double-distilled water (ddH 2 O). ...
Diaporthe is a large and taxonomically complex genus, with over a thousand epithets listed in Index Fungorum. The placement of many Diaporthe species remains confusing, and there is a lack of consensus on their taxonomy and phylogeny. In this study, we provide annotated notes on accepted or presumed species of Diaporthe up to 2023. Our notes cover 832 species and include information on their morphology, ecology, geographic distribution, molecular data, and pathogenicity, where available. Diaporthe cyatheae comb. nov., D. pseudobauhiniae nom. nov., D. xishuangbannaensis nom. nov., D. krabiensis sp. nov., and D. pseudobiguttulata nom. nov. are introduced in this paper. In addition, we list 331 species that were previously classified as Diaporthe but are no longer accepted as members of the genus. Our comprehensive review of Diaporthe species provides a resource for researchers and taxonomists, enabling accurate identification and classification, and enhancing our understanding ecological roles of these fungi.

Based on the morphological and phylogenetic analyses, we introduce a new species, Rhexoacrodictys melanospora, collected on decaying wood from terrestrial habitats in Yunnan, China. Phylogenetic analyses based on the combination of four loci (LSU, SSU, ITS and RPB2 data) demonstrated high support for establishing a new species within Rhexoacrodictys. The morphological characteristics of R. melanospora and the differences compared with the members of Rhexoacrodictys are also given in detail herein.

Luo, K.D. Hyde & H.Y. Su, which was regarded as the synonym of D. tectonae Doilom & K.D. Hyde by Dong et al. [7]. Thus, Distoseptispora currently contains 60 taxa, 38 of which were found in China [1][2][3]6,[8][9][10][11][12][13][14][15][16][17][18][19][20][21]. ...

Three new species of Distoseptispora, viz. D. mengsongensis, D. nabanheensis, and D. sinensis, are described and illustrated from specimens collected on dead branches of unidentified plants in Yunnan Province, China. Phylogenetic analyses of LSU, ITS, and TEF1 sequence data, using maximum-likelihood (ML) and Bayesian inference (BI), reveal the taxonomic placement of D. mengsongensis, D. nabanheensis, and D. sinensis within Distoseptispora. Both morphological observations and molecular phylogenetic analyses supported D. mengsongensis, D. nabanheensis, and D. sinensis as three new taxa. To extend our knowledge of the diversity of Distoseptispora-like taxa, a list of recognized species of Distoseptispora with major morphological features, habitat, host, and locality is also provided.

Notes: Acrodictyaceae is a monotypic family comprising saprobic dematiaceous hyphomycetes from terrestrial and freshwater environments (Ellis 1961;Cai et al. 2002c;Xia et al. 2017;Luo et al. 2019). The family is characterized by macronematous, mononematous conidiophores, monoblastic conidiogenous cells often elongating percurrently and brown, obovoid to pyriform, muriform conidia with schizolytic conidial secession. ...
Freshwater fungi comprises a highly diverse group of organisms occurring in freshwater habitats throughout the world. During a survey of freshwater fungi on submerged wood in streams and lakes, a wide range of sexual and asexual species were collected mainly from karst regions in China and Thailand. Phylogenetic inferences using partial gene regions of LSU, ITS, SSU, TEF1α, and RPB2 sequences revealed that most of these fungi belonged to Dothideomycetes and Sordariomycetes and a few were related to Eurotiomycetes. Based on the morphology and multi-gene phylogeny, we introduce four new genera, viz. Aquabispora, Neocirrenalia, Ocellisimilis and Uvarisporella, and 47 new species, viz.

Plant debris are habitats favoring survival and multiplication of various microbial species. During continuing mycological surveys of saprobic microfungi from plant debris in Yunnan Province, China, several Corynespora-like and Dendryphiopsis-like isolates were collected from dead branches of unidentified perennial dicotyledonous plants. Four barcodes, i.e., ITS, LSU, SSU and tef1-α, were amplified and sequenced. Morphological studies and multigene phylogenetic analyses by maximum likelihood and Bayesian inference revealed three new Corynespora species (C. mengsongensis sp. nov., C. nabanheensis sp. nov. and C. yunnanensis sp. nov.) and a new Kirschsteiniothelia species (K. nabanheensis sp. nov.) within Dothideomycetes, Ascomycota. A list of identified and accepted species of Corynespora with major morphological features, host information and locality was compiled. This work improves the knowledge of species diversity of Corynespora and Kirschsteiniothelia in Yunnan Province, China.

Three new species of Helminthosporium , H. nabanhensis , H. sinensis and H. yunnanensis collected on dead branches of unidentified plants in Xishuangbanna, China, were proposed by morphological and molecular phylogenetic analysis. Phylogenetic analysis of the combined data of ITS-SSU-LSU- TEF1 - RPB2 sequences was performed using Maximum-Likelihood and Bayesian Inference, although H. nabanhensis and H. sinensis lack the RPB2 sequences. Both molecular analyses and morphological data supported H. nabanhensis , H. sinensis and H. yunnanensis as three independent taxa within the Massarinaceae.
