Wood-inhabiting fungi are a cosmopolitan group and show a rich diversity, growing in the vegetation of boreal, temperate, subtropical, and tropical regions. , , and spp. nov. were found in the Yunnan-Guizhou Plateau, China, suggested here to be new fungal species in light of their morphology and phylogeny. is characterized by a grandinioid hymenophore and ellipsoid basidiospores; has a membranous hymenophore, a smooth hymenial surface with a speckled distribution, and absent cystidia; has a grandinioid hymenophore with a cream to slightly buff hymenial surface and cystidia of two types. Sequences of the ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed using the maximum likelihood, maximum parsimony, and Bayesian inference methods. After a series of phylogenetic studies, the ITS+nLSU analysis of the order Hymenochaetales indicated that, at the generic level, six genera (i.e., , , , , , and ) should be accepted to accommodate the members of sensu lato. According to a further analysis of the ITS dataset, was retrieved as a sister to ; formed a monophyletic lineage and then grouped with , , , and ; and was a sister to .
木生真菌是一个世界性的类群，具有丰富的多样性，生长在寒带、温带、亚热带和热带地区的植被中。在中国云贵高原发现了[具体物种1]、[具体物种2]和[具体物种3]新种，根据它们的形态和系统发育情况，这里认为它们是新的真菌物种。[具体物种1]的特征是具有颗粒状子实层体和椭圆形担孢子；[具体物种2]具有膜质子实层体，子实层表面光滑，有斑点分布，无囊状体；[具体物种3]具有颗粒状子实层体，子实层表面呈奶油色至浅米色，有两种类型的囊状体。对研究样本的ITS和nLSU rRNA标记序列进行了测定，并使用最大似然法、最大简约法和贝叶斯推断法进行了系统发育分析。经过一系列系统发育研究，刺革菌目（Hymenochaetales）的ITS + nLSU分析表明，在属的水平上，应接受六个属（即[属名1]、[属名2]、[属名3]、[属名4]、[属名5]和[属名6]）来容纳广义的[某个属名]的成员。根据对ITS数据集的进一步分析，[具体物种1]被检索为[另一个物种]的姐妹种；[具体物种2]形成一个单系谱系，然后与[其他几个物种]聚在一起；[具体物种3]是[另一个物种]的姐妹种。
