使用三个位点（RPB2、LSU 和 mtSSU）重建 Entolomataceae 的系统发育，并结合孢子形态（使用 SEM 和 TEM）来解决四个主要系统问题：1）Entolomataceae 的单系性； 2) Entolomataceae 内的属间关系； 3) Entolomataceae的属界定； 4) Entolomataceae 中的孢子进化。结果证实，Entolomataceae（Entoloma、Rhodocybe、Clitopilus、Richoniella 和 Rhodogaster）是单系的，粉红色孢子印和由外壁形成的具有凸起和/或脊的孢子的组合是该科的共源型。 Entolomataceae 由两个姐妹分支组成：一个由 Clitopilus 嵌套在 Rhodocybe 中，另一个由 Richoniella 和 Rhodogaster 嵌套在 Entoloma 中。 Entoloma 最好保留为一个属。 Entoloma s.l. 中较小的属。要么是多系的，要么是使其他属并系的。阴蒂型孢子源自红球状孢子。 Entolomataceae 的祖先孢子类型是 rhodocyboid 或 entolomatoid。分类学和命名法发生了变化，包括将Rhodocybe合并到Clitopilus中，并将相关物种转移到Clitopilus和Entoloma中。
The phylogeny of the Entolomataceae was reconstructed using three loci (RPB2, LSU and mtSSU) and, in conjunction with spore morphology (using SEM and TEM), was used to address four main systematic issues: 1) the monophyly of the Entolomataceae; 2) inter-generic relationships within the Entolomataceae; 3) genus delimitation of Entolomataceae; and 4) spore evolution in the Entolomataceae. Results confirm that the Entolomataceae (Entoloma, Rhodocybe, Clitopilus, Richoniella and Rhodogaster) is monophyletic and that the combination of pinkish spore prints and spores having bumps and/or ridges formed by an epicorium is a synapomorphy for the family. The Entolomataceae is made up of two sister clades: one with Clitopilus nested within Rhodocybe and another with Richoniella and Rhodogaster nested within Entoloma. Entoloma is best retained as one genus. The smaller genera within Entoloma s.l. are either polyphyletic or make other genera paraphyletic. Spores of the clitopiloid type are derived from rhodocyboid spores. The ancestral spore type of the Entolomataceae was either rhodocyboid or entolomatoid. Taxonomic and nomenclatural changes are made including merging Rhodocybe into Clitopilus and transferring relevant species into Clitopilus and Entoloma.
