Multilocus phylogenetic analysis using combined ITS, LSU, TUB2, and TEF1 sequence data, along with morphological assessments, identified three new species: A.bambusiparasitica sp. nov., A.qiannanensis sp. nov., and A.xiangxiense sp. nov. Descriptions, illustrations, and phylogenetic trees for the newly discovered species are provided and compared with closely related Apiospora species to enhance our understanding of the genus Apiospora.

In the present study, two new resupinate, adnate, wood-inhabiting fungal taxa, Botryobasidiumlatihyphum and B.zhejiangensis, are introduced based on morphological and molecular characteristics. A molecular phylogenetic study based on sequence data from the internal transcribed spacers (ITS) and the large subunit (nLSU) regions supported the two new species in the genus Botryobasidium. Maximum likelihood (ML), maximum parsimony (MP), and Bayesian inference (BIBI) were employed to perform phylogenetic analyses of these datasets. The new species B.latihyphum is characterized by its cream hymenial surface when fresh, olivaceous buff when dry, a monomitic hyphal system with clamp connections, the presence of clavate to tubular cystidia, basidia with six sterigmata, and broadly oval basidiospores measuring 7.9-10.2 × 3.2-4.3 μm. Botryobasidiumzhejiangensis sp. nov. is characterized by its white to buff-yellow hymenial surface when fresh, cream when dry, a monomitic hyphal system with clamp connections, lacking cystidia, basidia with six sterigmata, and broadly navicular basidiospores measuring 7.9-9.2 × 2.6-3.4 μm. The phylogenetic result inferred from ITS + nLSU sequence data revealed that B.latihyphum is closely related to B.vagum, B.laeve, B.subincanum, and B.incanum, while B.zhejiangensis is closely related to B.leptocystidiatum, B.subcoronatum, B.xizangense, and B.intertextum.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"116 ","pages":"73-89"},"PeriodicalIF":2.8,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12004073/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we introduce a novel genus, three novel species and one new record of fungi collected from mangrove environments in Pranburi, Prachuap Khiri Khan, Thailand. We establish Pseudomelanconiella as a new genus in Melanconiellaceae, to accommodate Pseudomelanconiellamangrovei, a saprobe from submerged decomposing wood of Avicenniamarina. Phylogenetic analysis indicates its close relation with Septomelanconiella, but they differ in the morphology of the conidia. Additionally, our analysis of Melanconiellaceae led to the reclassification of Melanconiellaloropetali to Sinodisculaloropetali and synonymizing Sinodisculacamellicola and Melanconiellacamelliae. This paper also introduces two other novel species: Peroneutypahibisci, a saprobe found on Hibiscustiliaceus and Pseudochaetosphaeronemabruguierae from Bruguieracylindrica, the first species in this genus reported as a mangrove fungus. A new record of Rimoramangrovei from Ceriopstagal is also reported. These discoveries emphasize the rich fungal diversity in mangrove ecosystems supporting further exploration of this unique environment.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"116 ","pages":"25-52"},"PeriodicalIF":2.8,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11997611/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144038723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
