Papiliomyces (Hypocreales, Sordariomycetes) was introduced to accommodate two species: Papiliomyces liangshanensis and Papiliomyces shibinensis. Later, Papiliomyces liangshanensis was renamed Ophiocordyceps liangshanensis. However, the Papiliomyces liangshanensis molecular data (Nepalese) used to establish the Papiliomyces genus was different from Ophiocordyceps liangshanensis (China) strains.This paper describes a new species, Papiliomyces longiclavatus, found in Yangchang District, Guiyang City, Guizhou Province, China. It is proposed, based on morphology and multilocus phylogeny (ITS, SSU, LSU, TEF1, RPB1 and RPB2). The new species is phylogenetically most closely related to Papiliomyces liangshanensis (Nepalese collections). However, Papiliomyces liangshanensis (Nepalese collections) requires morphological details and additional detection. The new species differs from other Papiliomyces species in having robust stroma with completely immersed perithecia, multi-septate ascospores, cylindrical secondary ascospores, two types of phialides and two types of conidia:longer α-conidia and longer β-conidia.
