Species of the basidiomycetous genus are widely distributed throughout temperate forests. Numerous studies on the taxonomy and phylogeny of have been conducted from the temperate zone in the Northern hemisphere, but few have been from subtropical forests. In this study, four new species, , , and from the subtropical mixed forests of Southwestern China, are described and illustrated based on morphological characteristics and phylogenetic analyses of the internal transcribed spacer regions (ITS) and the large subunit of the nuclear ribosomal RNA gene (LSU). Molecular analyses using Maximum Likelihood and Bayesian analysis confirmed the phylogenetic positions of these four new species. Anatomical comparisons among the closely related species in phylogenetic and morphological features are discussed. Four new species could be distinguished by the characteristics of basidiocarps, the color of the hymenophoral surface, the size of the basidia, the shape of the basidiospores and some other features.
担子菌纲属的物种广泛分布于整个温带森林。关于该属的分类学和系统发育学，已经在北半球的温带地区进行了大量研究，但来自亚热带森林的研究却很少。在本研究中，基于内部转录间隔区（ITS）和核糖体RNA基因大亚基（LSU）的形态特征和系统发育分析，描述并说明了来自中国西南部亚热带混交林的四个新物种，即[物种名1]、[物种名2]、[物种名3]和[物种名4]。使用最大似然法和贝叶斯分析的分子分析证实了这四个新物种的系统发育位置。讨论了系统发育和形态特征上密切相关物种之间的解剖学比较。这四个新物种可以通过担子果的特征、子实层表面的颜色、担子的大小、担孢子的形状和其他一些特征来区分。
