The genus has been reported from temperate and tropical areas and is an important constituent in forest ecosystems. However, the species diversity of in Southwest China (Yunnan) has been underestimated.
In this paper, descriptions based on morphological and multi-gene sequence data from internal transcribed spacer (ITS) region, large subunit ribosomal RNA gene (nrLSU), translation elongation factor 1-α (1α) and the polymerase II second largest subunit (2) of three new species from Southwest China (Yunnan) are reported.
Two of these were characterized by orange pileus and globose to subglobose basidiospores: and . While has orange red colored basidiocarps with conspicuously pellucid-striate pattern, and a fibrillose stipe with longitudinally striations, has a brownish orange to brown fruiting body with light white pruinae and 2-spored basidia. is characterized by brown to flesh-colored basidioma, prominently striate to sulcate pileus and globose to subglobose basidiospores.
The three new species were described, illustrated and compared with closely related species in morphology and phylogeny.
该属已在温带和热带地区被报道，是森林生态系统中的重要组成部分。然而，中国西南部（云南）该属的物种多样性一直被低估。
本文报道了基于来自中国西南部（云南）的三个新物种的形态学以及内转录间隔区（ITS）、核糖体大亚基RNA基因（nrLSU）、翻译延伸因子1-α（1α）和聚合酶II第二大亚基（2）的多基因序列数据的描述。
其中两个的特征为菌盖橙色，担孢子球形至近球形：[物种1名称]和[物种2名称]。而[物种3名称]的担子果橙红色，具明显的透明条纹图案，菌柄具纤维状且有纵向条纹，[物种2名称]有橙褐色至褐色的子实体，具浅白色粉霜，担子有两个孢子。[物种1名称]的特征为褐色至肉色的担子果，菌盖显著具条纹至具沟，担孢子球形至近球形。
描述了这三个新物种，并在形态学和系统发育方面与近缘物种进行了比较。
