Abstract
During the investigation of discomycetes in Yunnan, China, ten saprotrophic species were discovered on fallen leaves and decaying wood.Among them, four species were identified as new species within Hyphodiscaceae based on phylogenetic analyses of the combined LSU and ITS datasets and morphological evidence.Longistipes is established as a new genus with two new species, L. albus and L. niger, typified by L. niger.This genus is distinguished by unique characteristics such as long stipes, white and long hairs, and broad lanceolate paraphyses that exceed the length of the asci.Additionally, two new species, Hyphopeziza macrospora and Hyphodiscus pseudotanii, are introduced.Three known species, Chalara bambusicola, Nagrajchalara neonawawii and Nagrajchalara yongnianii, are described for the first time in their sexual morphs, with C. bambusicola being reported for the first time on Gleditsia sp.Furthermore, Dicephalospora chiangraiensis is reported as a new geographical record from China, and new collections of Erioscyphella hainanensis and Lachnellula subtilissima are discovered in Yunnan Province.All described species are supported by detailed descriptions, illustrations, and multi-gene analyses.
