This study identified several new species and records of helicosporous hyphomycetes through morphological and molecular phylogenetic analysis. These findings expand the classification information of helicosporous hyphomycetes and provide a foundation for further research and utilization of their resources.
Helicosporous hyphomycetes have the potential to produce a variety of bioactive compounds. However, the strain resources of this fungal group are relatively scarce, which limits their further exploitation and utilization. In this study, based on phylogenetic analyses of combined ITS, LSU, RPB2, and TEF1 alpha sequence data and the morphology from 11 isolates, we introduce four new species of helicosporous hyphomycetes, viz. Helicoma wuzhishanense, Helicosporium hainanense, H. viridisporum, and Neohelicomyces hainanensis, as well as three new records, viz. Helicoma guttulatum, H. longisporum, and Helicosporium sexuale. Detailed morphological comparisons of the four new species that distinguish them are provided.
