Wood-inhabiting fungi play crucial roles as decomposers in forest ecosystems and, in this study, two new wood-inhabiting corticioid fungi, and , are proposed, based on a combination of morphological features and molecular evidence. is characterised by effused basidiomata with smooth to floccose hymenial surface, a monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. is characterised by resupinate basidiomata with tuberculate to minutely-grandinioid hymenial surface, septate cystidia and cylindrical to allantoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed with Maximum Likelihood, maximum parsimony and Bayesian Inference methods. These analyses showed that the two new species clustered into , in which grouped with and formed a singleton lineage. In addition, an identification key to Chinese is provided.
木生真菌在森林生态系统中作为分解者发挥着关键作用。在本研究中，基于形态特征和分子证据相结合的方法，提出了两种新的木生革菌属真菌，即[真菌名称1]和[真菌名称2]。[真菌名称1]的特征是平伏的担子果，子实层表面光滑至絮状，单系菌丝系统，有锁状联合的生殖菌丝和椭圆形担孢子。[真菌名称2]的特征是反卷的担子果，子实层表面有瘤状至微小颗粒状，有隔的囊状体和圆柱形至腊肠形担孢子。对所研究样本的ITS和nLSU rRNA标记序列进行了测定，并采用最大似然法、最大简约法和贝叶斯推断法进行了系统发育分析。这些分析表明，这两个新物种聚为[分类群名称]，其中[真菌名称1]与[相关真菌名称1]聚在一起，[真菌名称2]形成一个单独的谱系。此外，还提供了中国革菌属的检索表。
