Five new species, two new sexual morph reports, and one new geographical record of (Amphisphaeriales, Sordariomycetes) isolated from bamboo in Yunnan, China.

is an important genus in the Apiosporaceae family with a worldwide distribution. They exhibit different lifestyles including pathogenic, saprophytic, and endophytic. In this study, we aimed to explore the associated with bamboo and collected 14 apiospora-like taxa from the forests of Yunnan Province, China. Morphological and phylogenetic analyses (combined ITS, LSU, 1-, and 2 sequence data) confirmed that these collections belong to Apiospora s. str. and reports five new species (viz., , and ). New sexual morphs of asexually typified and species, and a new geographical record of are also reported. The findings of this study not only enhance the diversity of bambusicolous fungi in the region of Yunnan, but also geographical distribution of some known species.
