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.

Abstract: This article deals with the taxonomy of three species belonging to Cortinarius subgenus Telamonia section Flexipedes. The micromorphologies and mostly ITS gene regions were examined from the lectotypes and some syntypes of Cortinarius phaeopygmaeus J. Favre and C. rusticellus J. Favre. Cortinarius phaeopygmaeus appeared to be a previously unrecognized species. Cortinarius rusticellus is reduced to a synonym of C. comatus J. Favre. Its lectotype and protologue agreed with C. comatus. The syntype of C. rusticellus was conspecific with C. lamoureae Bon. Cortinarius chrysophilus is described as new from Salix vegetation on boreal seashores and in the alpine zone. It belongs to the C. cucumisporus complex.
