Three new species of Coltricia from southern China are described on the basis of morphological characters and molecular analyses. Phylogenetic analyses based on nuc rDNA ITS1-5.8S-ITS2 and partial 28S rDNA, and partial sequences of genes for RNA polymerase II subunits 1 and 2 confirmed the generic placement of the three new species. Coltricia lateralis is characterized by small, laterally stipitate basidiocarps, obtuse pileus margin, cinnamon-buff to honey yellow pore surface, and broadly ellipsoid basidiospores that measure 7-8 × 5-6 µm. Coltricia rigida is characterized by large, woody-hard fan-shaped basidiocarps, small pores (7-8 per mm), presence of septate sclerified hyphae, and subglobose to globose basidiospores that measure 6-7 × 5-6.5 μm. Coltricia wenshanensis is characterized by centrally stipitate basidiocarps, a distinctly concentrically zonate and sulcate pileal surface, large pores (0.5-2 per mm), and broadly ellipsoid to subglobose basidiospores that measure 7.5-8 × 6-7 µm.
基于形态特征和分子分析,描述了来自中国南方的三个皱盖乌芝新物种。基于核糖体DNA ITS1-5.8S-ITS2、部分28S核糖体DNA以及RNA聚合酶II亚基1和2的部分基因序列的系统发育分析,证实了这三个新物种的属级地位。侧生皱盖乌芝的特征为小型、具侧生柄的担子果,菌盖边缘钝圆,孔表面肉桂浅黄色至蜜黄色,以及宽椭圆形的担孢子,大小为7-8×5-6μm。硬皱盖乌芝的特征为大型、木质坚硬的扇形担子果,小孔(每毫米7-8个),存在具隔膜的硬化菌丝,以及近球形至球形的担孢子,大小为6-7×5-6.5μm。文山皱盖乌芝的特征为具中央柄的担子果,菌盖表面有明显的同心环带和沟纹,大孔(每毫米0.5-2个),以及宽椭圆形至近球形的担孢子,大小为7.5-8×6-7μm。
