Polycephalomyces yunnanensis (Hypocreales), a new species of Polycephalomyces parasitizing Ophiocordyceps nutans and stink bugs (hemipteran adults)

摘要

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 (alpha- and beta-conidia) and phialides (alpha- and beta-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-1 alpha, rpb1 and rpb2) data supported the treatment of this fungus as a distinct species.
