In this study, two novel species in Ophiocordyceps were revealed parasitising Hepialidae larva buried in soil. Ophiocordycepsalbastroma was morphologically characterised by white stromata, solitary and cylindrical conidiogenous cells and smooth ovoid or ellipsoidal conidia. Ophiocordycepsnigristroma was characterised by woody and dark brown stromata, monophialidic, swollen base and lageniform conidiogenous cells and smooth fusiform or oval conidia. The two new species formed a separate clade, respectively, based on the phylogenetic analyses of a combined dataset including nrSSU, nrLSU, rpb1, rpb2, and tef-1α, as well as a dataset of mitochondrial 14 protein coding genes (PCGs). They were all closely grouped with O.sinensis. The mitochondrial genomes of them were first reported. Their mitogenomes were all typical of circular molecules, with positive AT and GC skew, similar GC content, similar genetic composition, similar codon usage and conservative gene positions. However, the length of the mitogenomes varied. Changes in the length of the genes were the leading cause of changes in the length of mitochondrial genome of Ophiocordyceps. The discovery and identification of new Ophiocordyceps species and analysis their mitochondrial genomes may serve as foundations for phylogeny and diversity research within the genus Ophiocordyceps.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"109 ","pages":"49-72"},"PeriodicalIF":2.8,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11450462/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142382087","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}
