This study introduces Parastagonosporayunnanensis, Para.zhaotongensis, Phaeoseptoriellapoaceicola. Parastagonosporayunnanensis is characterized by ampulliform or globose to subglobose conidiogenous cells, with conidia that are cylindrical to subcylindrical, 0-1-septate, rounded at the apex and slightly truncate at the base. Parastagonosporazhaotongensis features similar globose to subglobose conidiogenous cells but with 0-3-septate, cylindrical to subcylindrical conidia. Phaeoseptoriellapoaceicola is distinguished by its globose to subglobose conidiogenous cells and phragmosporous conidia that are initially hyaline, turn pale yellowish at maturity, and are 7-septate, cylindrical to subcylindrical, either straight or slightly curved. These discoveries underscore the significance of exploring and accurately identifying fungal taxa within Ascomycota, highlighting the species richness and potential for new species discoveries in grass-based habitats. The findings from this study expand our understanding of the taxonomy and phylogeny of grassland-associated Ascomycota, providing a foundation for further ecological and taxonomic studies of these fungi within their natural environments.","PeriodicalId":48720,"journal":{"name":"Mycokeys","volume":"109 ","pages":"239-263"},"PeriodicalIF":2.8,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11487144/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142478280","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}

P.alpinicola, P.camelliicola, P.cyclosora, P.eriobotryae, P.gardeniae, P.hederae, P.machiliana and P.mangifericola. Multi-locus (ITS, tef1-α and tub2) phylogenetic analyses were performed using maximum-likelihood and Bayesian inference to reveal their taxonomic placement within Pestalotiopsis. Both molecular phylogenetic analyses and morphological comparisons supported them as eight independent taxa within Pestalotiopsis.

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.
