Four new wood-inhabiting fungal species, , , and , are proposed based on a combination of morphological and molecular evidence. is characterized by resupinate basidiomata with colliculose to tuberculate hymenial surface and broadly ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. is characterised by resupinate basidiomata with smooth, cream hymenial surface and ellipsoid, hyaline, thin-walled to slightly thick-walled basidiospores. is characterized by pruinose basidiomata with reticulate hymenial surface, presence of three kinds of cystidia and larger basidiospores (6.7-8.9 × 4.4-5.4 µm). is characterized by coriaceous basidiomata and ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. The phylogenetic analyses based on molecular data of the internal transcribed spacer (ITS) region sequences revealed that the four new species belonged to . grouped with . clade was sister to a clade comprised of . was sister to . was closely related to .
基于形态学和分子证据，提出了四个新的木生真菌物种，即[物种名1]、[物种名2]、[物种名3]和[物种名4]。[物种名1]的特征是平伏的担子果，子实层表面具小瘤状至瘤状，担子孢子宽椭圆形、透明、壁稍厚、表面光滑。[物种名2]的特征是平伏的担子果，子实层表面光滑、呈奶油色，担子孢子椭圆形、透明、壁薄至稍厚。[物种名3]的特征是具粉霜的担子果，子实层表面具网状，有三种囊状体，担子孢子较大（6.7 - 8.9×4.4 - 5.4 µm）。[物种名4]的特征是革质的担子果和椭圆形、透明、壁稍厚、表面光滑的担子孢子。基于内部转录间隔区（ITS）区域序列的分子数据进行的系统发育分析表明，这四个新物种属于[所属类别]。[物种名1]与[相关物种1]聚在一起。[物种名1]分支是一个由[相关物种2]组成的分支的姐妹分支。[物种名2]是[相关物种3]的姐妹分支。[物种名3]与[相关物种4]密切相关。
