In their asexual morph, both genera share similar morphology in conidiophores and conidiogenous cell characteristics but differ in the development of conidiophores. The members of Clonostachys are distributed worldwide with the majority occurring in the tropics and the species are commonly reported as soil-borne fungi but also reported as endophytes, epiphytes, and saprotrophs. During a microfungi survey in Xizang, China, six collections of fresh and healthy Ageratinaadenophora and Houttuyniacordata leaves were obtained. The taxonomy of these collections was investigated through a combination of morphological analysis and multigene phylogenetic analysis using Maximum likelihood and Bayesian inference. The newly generated sequences were clustered within Clonostachys and Sesquicillium, showing hyphomycetes asexual morph. The results revealed three new Clonostachys species viz, Clonostachyslinzhiensis, C.motuoensis, and C.yadongensis. This research sheds light on the overlooked fungal diversity in Xizang, China, expanding the known fungal biodiversity in the region. Additionally, two new combinations, Sesquicilliumaquaticum and S.shanghaiense for C.aquatica and C.shanghaiensis, and one synonymy, C.viticola for C.swietenia are established, respectively.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"115 ","pages":"43-66"},"PeriodicalIF":2.8,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11920821/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665212","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 study, a new species: Cytosporellafuligomixta is described based on a strain isolated from the sooty mould community on Quercusrobur leaves in Poland. The phylogenetic analyses including sequences of two loci (LSU, mtSSU) showed that Cytosporella species, together with members of four other non-lichenized, plant associated or fungicolous genera, namely Cladosterigma, Neoacrodontiella, Nothoramularia and Vanderaaea, form a sister group to lichenized and lichenicolous fungi from the family Gomphillaceae and order Graphidales. Previously, Cladosterigma was resolved as a member of Gomphillaceae using multi-locus (mtSSU, SSU, LSU, ITS, rpb2, tef1) and two-locus (LSU, mtSSU) sequence analyses, while Cytosporella, Neoacrodontiella, Nothoramularia were shown to belong to this family using LSU sequence analyses. However, none of them resolved these genera as a sister group to lichenized members of Gomphillaceae. The placement of the genus Vanderaaea within Gomphillaceae is shown here for the first time. Due to phylogenetic, morphological and ecological characteristics a new subfamily Cladosterigmoideae is described for these five non-lichenized genera.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"115 ","pages":"1-18"},"PeriodicalIF":2.8,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11907247/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651577","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}
