Cyptotrama was divided into several sections, of which sect. Xerulina was often treated as a separate genus by some mycologists. In this study, collections of Cyptotrama from East Asia, Southeast Asia, and South Asia were studied. For comparison, materials from North America and New Zealand were analysed. Our multi-gene phylogenetic analyses indicated that Cyptotrama is monophyletic and Xerulina should be treated as a section within the genus Cyptotrama. Different scenarios of morphological character evolution in Cyptotrama are discovered. A total of seven species of Cyptotrama can be recognized from Asia, three of which, Cyptotrama angustispora, C. glabra, and C. shennongjia, are new to science. Meanwhile, three taxa previously placed in Xerulina or Marasmius were proved to be members of Cyptotrama, and the new combinations, namely Cyptotrama trogioides, C. megaspora, and C. myochroa, are accordingly proposed. A key for the diagnosis of worldwide Cyptotrama species is provided.
隐孔菌属被划分为几个组，其中干隐孔菌组常被一些真菌学家视为一个独立的属。在本研究中，对来自东亚、东南亚和南亚的隐孔菌属标本进行了研究。为作比较，还分析了来自北美洲和新西兰的材料。我们的多基因系统发育分析表明，隐孔菌属是单系的，干隐孔菌组应被视为隐孔菌属内的一个组。发现了隐孔菌属形态特征进化的不同情况。亚洲共识别出7种隐孔菌，其中3种，即窄孢隐孔菌、光滑隐孔菌和神农架隐孔菌，为新物种。同时，先前置于干隐孔菌组或小皮伞属的3个分类单元被证明是隐孔菌属的成员，因此提出了新组合，即类毛栓隐孔菌、大孢隐孔菌和肉色隐孔菌。提供了一个用于鉴定世界范围内隐孔菌属物种的检索表。
