Two new corticioid fungal species, and spp. nov. are proposed based on a combination of morphological features and molecular evidence. is characterized by the resupinate basidiomata with the pruinose hymenial surface, a monomitic hyphal system with simple-septate generative hyphae and subcylindrical basidiospores measuring as 3.5-6.7 × 1.5-2.7 µm. is characterized by having a smooth hymenophore covered by orange hymenial surface, the presence of rhizomorphs, subulate cystidia, and narrower ellipsoid to ellipsoid basidiospores. Sequences of ITS+nLSU nrRNA gene regions of the studied specimens were generated and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that two new species clustered into genus , in which was sister to with high supports (100% BS, 100% BT, 1.00 BPP); morphologically differing by a pale orange to greyish orange and densely cracked hymenial surface. Another species was closely grouped with with lower supports; morphologically having yellow to reddish yellow hymenial surface, and smaller cystidia measuring as 31-48 × 2.3-4.8 µm.
基于形态特征和分子证据，提出了两个新的革菌属真菌物种，即[物种名1]和[物种名2]新种。[物种名1]的特征为平伏的担子果，其菌褶表面有粉霜，菌丝系统单系，有简单隔膜的生殖菌丝，以及亚圆柱形的担孢子，大小为3.5 - 6.7×1.5 - 2.7微米。[物种名2]的特征为有光滑的子实层体，表面覆盖橙色菌褶，有菌索、钻形囊状体，以及较窄的椭圆形至椭圆形担孢子。对所研究标本的ITS + nLSU nrRNA基因区域序列进行了测定，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。这些系统发育分析表明，两个新物种聚为革菌属，其中[物种名1]与[物种名3]为姐妹关系，支持率较高（100% BS，100% BT，1.00 BPP）；形态上的差异在于菌褶表面为浅橙色至灰橙色且有密集裂纹。另一个物种[物种名4]与[物种名5]关系密切，但支持率较低；形态上其菌褶表面为黄色至红黄色，囊状体较小，大小为31 - 48×2.3 - 4.8微米。
