Multi-gene phylogenetic evidence indicates that Pleurodesmospora belongs in Cordycipitaceae (Hypocreales, Hypocreomycetidae) and Pleurodesmospora lepidopterorum sp. nov. On pupa from China

Abstract

A new species, Pleurodesmospora lepidopterorum, isolated from a pupa, is introduced. Morphological comparisons and phylogenetic analyses based on multigene datasets (ITS+RPB1+RPB2+TEF) support the establishment of the new species. Pleurodesmospora lepidopterorum is distinguished from P. coccorum by its longer conidiogenous pegs located in the terminal or lateral conidiophores, and smaller subglobose or ellipsoidal conidia. A combined dataset of RPB1, RPB2, and TEF confirmed the taxonomic placement of Pleurodesmospora in Cordycipitaceae for the first time.
