Podonectria sichuanensis, a potentially mycopathogenic fungus from Sichuan Province in China

Abstract

Podonectria sichuanensis sp. nov., a fungus associated with a phaeosphaeriacous species (Neostagonosporella sichuanensis) or occasionally found on scale insect (Kuwanaspis phyllostachydis), collected from Phyllostachys heteroclada forest in Sichuan Province, China. Podonectria sichuanensis differs from other Podonectria species in having distinct stroma covered with intricately pigmented hyphae, wider ostiole, relatively long, thin and multiseptate ascospores. Phylogenetic analyses based on ITS and LSU sequences are performed, and morphological descriptions are provided.
