摘要

Neostagonosporella species are described as saprobic or parasitic fungi on bamboos (Poaceae) with only three taxa, in which N. sichuanensis and N. bambusicola are recorded in China on dead leaves, living stems and branches, and N. sasae is reported from Japan on living leaves of Sasa borealis and unidentified bamboos. Chimonobambusa is an important bamboo resource in China, and the diversity of fungal species inhabiting Chimonobambusa bamboos remains unresolved. In this study, we describe two newly discovered species, viz. Neostagonosporella fulvomarginata and N. flavispora, based on detailed morphological examinations and multi-locus phylogenetic analyses (ITS, LSU, SSU, and TEF1-α). In addition, two known species, N. bambusicola and N. sichuanensis, have also been reported as new records for their host plants, and the asexual morph of N. bambusicola is described here for the first time.
