This study described two new Penicillium species, i.e., P.lentum and P.tibetense, discovered in China. They have been identified and characterized through morphological examination and both single gene and multigene phylogenetic analyses. Based on these analyses, P.lentum was classified within the section Brevicompacta, while P.tibetense was placed in the section Lanata-Divaricata. Both species exhibited the morphological features typical of their respective sections. Penicilliumlentum is characterized by restricted growth with dense colonies on agar media and predominantly generates terverticillate conidiophores. Penicilliumtibetense demonstrates rapid growth on media and has vigorous growth on CYA at 30 °C, producing biverticillate conidiophores.

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}
