Based on multi-gene phylogenetic analyses of nrITS, nrLSU, and <i>tef</i>-1α sequences, two collections were confirmed to belong to the <i>Psathyrella</i> sections <i>Atomatae</i> and <i>Hydrophilae</i>. Morphologically, <i>Psathyrella qujinguniversitatica</i> (<i>Psathyrella</i> sect. <i>Atomatae</i>) is characterized by small basidiomata, a beige to light brown pileus, large basidiospores, and partially thick-walled cheilocystidia, while <i>P. yunnanensis</i> (<i>Psathyrella</i> sect. <i>Hydrophilae</i>) is characterized by a pileus that gradually changes from orange-brown to lighter towards the margin, with the edge light brown to brown, distinct striations, a fibrillose veil, larger basidia, and partially thick-walled cheilocystidia. Descriptions, illustrations, and phylogenetic analyses of the two new species are provided. In addition, the present study updates the number of <i>Psathyrella</i> species reported from China to 55, along with their known distribution.</p>","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"129 ","pages":"1-22"},"PeriodicalIF":3.6,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12946828/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147327862","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}
