尽管最近对伞菌科（伞菌目、担子菌门）进行了分子系统分析，但对于这一粉红色孢子真菌的世界性家族，由形态学和系统发育证据支持的可靠的属分类仍未得到解决。在这里，使用三个核蛋白编码基因区域，即线粒体 ATP 合酶亚基 6 (atp6)、核 RNA 聚合酶亚基 II (rpb2) 和核翻译延伸因子亚基 1-α (tef1)，对两个主要进化枝之一（Rhodocybe-Clitopilus）进行了系统发育分析。在强有力的统计支持下解决了五个单系类群，并提出了一组用于描述属的形态特征。在此提出的修订分类中，保留了 Clitopilus，修改了 Rhodocybe，恢复了先前被认为是 Rhodocybe 同义词的两个属（Clitopilopsis 和 Rhodophana），并将 Clitocella 描述为新的。
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-alpha (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.
