Wood-inhabiting fungi play a fundamental role in ecosystem processes, particularly in wood degradation and the recycling of organic matter. In this study, a new genus, , and five new species, viz. , , , , and , are described from China and illustrated based on morphological characteristics and molecular phylogenetic analyses. Sequences of the ITS+nLSU genes were used for the phylogenetic analyses using Maximum Likelihood, Maximum Parsimony, and Bayesian Inference methods. The phylogram of the family Hydnaceae, based on the ITS+nLSU rDNA gene regions, included four genera; , , and The topology based on these sequences revealed that was closely related to , and was grouped with . The taxon was sister to the clade that included and . The species was grouped closely with and . All new taxa can be readily recognized by their macroscopic and anatomical characteristics. The five new species, closely related taxa in the phylogenetic tree, and morphologically similar species are discussed.
木生真菌在生态系统过程中发挥着重要作用，特别是在木材降解和有机物循环方面。在本研究中，从中国描述了一个新属和五个新物种，即[具体属名]、[具体物种名1]、[具体物种名2]、[具体物种名3]、[具体物种名4]和[具体物种名5]，并根据形态特征和分子系统发育分析进行了图示。使用ITS + nLSU基因序列，采用最大似然法、最大简约法和贝叶斯推断法进行系统发育分析。基于ITS + nLSU rDNA基因区域的齿菌科系统发育树包括四个属，即[属名1]、[属名2]、[属名3]和[属名4]。基于这些序列的拓扑结构表明，[物种名1]与[物种名2]密切相关，[物种名3]与[物种名4]聚在一起。分类单元[物种名5]是包括[物种名6]和[物种名7]的分支的姐妹群。物种[物种名8]与[物种名9]和[物种名10]紧密聚在一起。所有新分类单元都可以通过其宏观和解剖特征轻松识别。讨论了五个新物种、系统发育树中密切相关的分类单元以及形态相似的物种。
