, ) is a genus traditionally defined by corticioid basidiocarps, in contrast to the rest of the class, which is characterized by gelatinous ones. In the traditional circumscription the genus is polyphyletic, and the monotypic family is paraphyletic. Aiming for a more concise delimitation, we revise with a novel phylogeny based on sequences of nrDNA (SSU, ITS, LSU) and protein-coding genes (RPB1, RPB2, TEF1-α) We establish that monophyletic is best characterized not by the corticioid morphology, but by a combination of traits: hyphal clamps, predominantly aseptate thin-walled basidiospores, and low content of carotenoid pigments. In our updated definition, encompasses five well-supported phylogenetic clades divided into two morphological groups: (i-iii) taxa with arid corticioid basidiocarps, including the generic type ; and (iv-v) newly introduced members with gelatinous basidiocarps, like and . The remaining corticioid species of are morphologically distinct and belong to the : our analysis places the carotenoid-rich close to , and we transfer the clamps-lacking group to In addition, we address genera related to historically and morphologically, such as , and . Overall, we describe twenty-four new species and propose nine new combinations in both and .
（此处原文开头逗号多余，推测可能有误，暂按此翻译）是一个传统上由革菌状担子果定义的属，与该类群的其他部分形成对比，后者的特征是胶质担子果。在传统的分类界定中，该属是多系的，而单型科是并系的。为了实现更简洁的界定，我们基于nrDNA（SSU、ITS、LSU）和蛋白质编码基因（RPB1、RPB2、TEF1-α）的序列构建了一个新的系统发育树来修订（此处“修订”后缺少具体修订对象，推测原文有误）。我们确定单系的（此处同样缺少具体所指，推测原文有误）的最佳特征不是革菌状形态，而是一系列特征的组合：菌丝锁状联合、主要无隔膜的薄壁担孢子以及类胡萝卜素色素含量低。在我们更新的定义中，（此处又缺少具体所指，推测原文有误）包括五个得到充分支持的系统发育分支，分为两个形态学组：（i - iii）具有干旱革菌状担子果的类群，包括模式属；以及（iv - v）新引入的具有胶质担子果的成员，如（此处缺少具体物种名，推测原文有误）和（此处缺少具体物种名，推测原文有误）。（此处“的其余革菌状物种”缺少所属范围，推测原文有误）在形态上是不同的，属于（此处缺少具体属名，推测原文有误）：我们的分析将富含类胡萝卜素的（此处缺少具体物种名，推测原文有误）置于（此处缺少具体属名，推测原文有误）附近，并且我们将缺乏锁状联合的（此处缺少具体类群名，推测原文有误）组转移到（此处缺少具体属名，推测原文有误）。此外，我们从历史和形态学角度探讨了与（此处缺少具体属名，推测原文有误）相关的属，如（此处缺少具体属名，推测原文有误）、（此处缺少具体属名，推测原文有误）和（此处缺少具体属名，推测原文有误）。总体而言，我们描述了二十四个新物种，并在（此处缺少具体属名，推测原文有误）和（此处缺少具体属名，推测原文有误）中提出了九个新组合。
