Abstract

Polycephalomyces yunnanensis is described as a new species that parasitizes Ophiocordyceps nutans and stink bugs (hemipteran adults). It is characterized by the production of a viscous mass at the apex of its synnema, and it has two types of conidia (α- and β-conidia) and phialides (α- and β-phialides). A morphological and ecological investigation revealed that P. yunnanensis is distinct from any known species in the genus. Phylogenetic analyses based on the ITS and 5-locus (nrSSU, nrLSU, tef-1α, rpb1 and rpb2) data supported the treatment of this fungus as a distinct species.
