Taxonomy plays a central role in understanding the diversity of life, translating the products of biological exploration and discovery specimens and observations into systems of names that settle a "classification home" to taxa. The ectomycorrhizal basidiomycetes family Thelephoraceae has been understudied in subtropical ecosystems. Many species of Thelephoraceae are important edible and medicinal fungi, with substantial economic value. Four new species, , , and , are proposed based on a combination of the morphological features and molecular evidence. is characterized by the resupinate basidiomata having a tuberculate pileal surface hymenial, and the presence of the subglobose to globose basidiospores (9-12 × 7-9 µm). is solitary coriaceous infundibuliform gray-brown basidiomata with a presence of the subclavate basidia and subglobose to globose basidiospores (6-8 × 5-7 µm). is typical of the laterally stipitate basidiomata having a smooth, umber to coffee hymenial surface, a monomitic hyphal system with clamped generative hyphae, and the presence of the subglobose basidiospores (7-10 × 6-8 µm). is typical of the arachnoid basidiomata having a smooth, gray, or dark gray hymenial surface, a monomitic hyphal system with clamped generative hyphae, and the presence of the subglobose to globose basidiospores (7-9 × 6-8 µm). Sequences of ITS+nLSU+mtSSU genes were used for the phylogentic analyses using maximum likelihood, maximum parsimony, and Bayesian inference methods. The three genes' (ITS+nLSU+mtSSU) phylogenetic analysis showed that the genera and grouped together within the family Thelephoraceae and three new species were nested into the genus , and one new species was nested into the genus .
分类学在理解生命多样性方面发挥着核心作用，它将生物探索和发现的产物（标本和观察结果）转化为命名系统，为分类单元确定一个“分类归属”。外生菌根担子菌科革菌科在亚热带生态系统中研究较少。革菌科的许多物种是重要的食用和药用真菌，具有很高的经济价值。基于形态特征和分子证据，提出了四个新物种，即 、 、 和 。 的特征是平伏的担子果，菌盖表面有瘤状，子实层，以及近球形至球形的担孢子（9 - 12 × 7 - 9 µm）。 是单个革质漏斗状灰褐色担子果，有近棒状的担子和近球形至球形的担孢子（6 - 8 × 5 - 7 µm）。 的典型特征是侧生柄状担子果，子实层表面光滑，呈赭色至咖啡褐色，单系菌丝系统，有具锁状联合的生殖菌丝，以及近球形的担孢子（7 - 10 × 6 - 8 µm）。 的典型特征是蛛网状担子果，子实层表面光滑，呈灰色或深灰色，单系菌丝系统，有具锁状联合的生殖菌丝，以及近球形至球形的担孢子（7 - 9 × 6 - 8 µm）。使用ITS + nLSU + mtSSU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。三个基因（ITS + nLSU + mtSSU）的系统发育分析表明， 属和 属在革菌科内聚在一起，三个新物种嵌套在 属中，一个新物种嵌套在 属中。
