Despite the recent molecular systematic analyses of the Entolomataceae (Agaricales, Basidiomycota), a robust classification of genera supported by morphological and phylogenetic evidence remains unresolved for this cosmopolitan family of pink-spored fungi. Here, a phylogenetic analysis for one of the two major clades (Rhodocybe-Clitopilus) was conducted using three nuclear protein-coding gene regions, the mitochondrial ATP synthase subunit 6 (atp6), the nuclear RNA polymerase subunit II (rpb2) and the nuclear translation elongation factor subunit 1-α (tef1). Five monophyletic groups are resolved with strong statistical support and a set of morphological features for delineation of genera is presented. In the revised classification proposed here, Clitopilus is retained, Rhodocybe is emended, two genera previously accepted as synonyms of Rhodocybe (Clitopilopsis and Rhodophana) are resurrected and Clitocella is described as new.
