Three fungal taxa were collected from dead branches in Sichuan and Yunnan Provinces, China. Two new species, Brunneosporopsis gen. nov. and species B. yunnanensis sp. nov., were introduced based on their unique characteristics. Additionally, a new species in Allocryptovalsa, A. xishuangbanica sp. nov., was described. The collection of an interesting hypocrealean fungus, Stilbocrea gracilipes, was also reported.
Three fungal taxa were collected on dead branches of wood during fieldwork in Sichuan and Yunnan Provinces, China. The new generic name Brunneosporopsis gen. nov. and species B. yunnanensis sp. nov. are introduced for a novel taxon characterized by globose to subglobose and dark olivacous-brown conidia. Phylogenetic analyses based on combined LSU, SSU and tef1-alpha loci strongly support the monophyly of this taxon and place it in the subclass Diaporthomycetidae. It could not be assigned to any currently recognized families in the subclass and was, therefore, placed in the Diaporthomycetidae genera incertae sedis. A second taxon represents a new species in Allocryptovalsa based on an analysis of the sequence datasets of ITS and btub loci of the novel, brown-spored sexual morphic species. This taxon is described here as A. xishuangbanica sp. nov. An interesting hypocrealean fungus producing synnemata, Stilbocrea gracilipes, was collected from dead wood of an unknown host from Sichuan Province and is reported here, with asexual morph from both the host and culture as well as LSU, ITS, tef1-alpha, rpb2 and rpb1 sequence data.
