Gymnopilus dilepis and G. lepidotus (Agaricales, Basidiomycota): synonym or not?

Abstract

Abstract: Currently described as part of Hymenogastraceae, Gymnopilus comprises up to 200 species distributed around the world, and 23 of these are found in Brazil. In this study, we discovered interesting specimens of G. dilepis growing with Zoysia japonica (Poaceae) grass in an urban area in the State of Paraíba. Originally described from Sri Lanka, this report treats a new and interesting record of this entity from Brazil. We also discuss whether to consider G. lepidotus as a synonym of G. dilepis based on morphological and phylogenetic evidence. Thus, as conclusion we prefer to maintain them as distinct entities and our material as G. dilepis based on morphological and ecological aspects.
