Three new species of (Tubeufiales, Tubeufiaceae) from freshwater and terrestrial habitats in China.

species are a group of helicosporous hyphomycetes with the potential to produce secondary metabolites. During our investigation of helicosporous fungi, six collections were isolated from both terrestrial and freshwater habitats in Guizhou Province, China. Based on multigene phylogenetic analysis (ITS, LSU, and ), coupled with morphological data, three new species, viz. , and were established. A list of accepted species with molecular data was provided. The strain of (UAMH 10535) was synonymised under based on molecular data.
