Two new species of , and , are described and illustrated from Southwest (SW) China based on morphology, ecology and phylogenetic analyses by the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU). is characterized by big basidiocarps (up to 18 cm in diam), guttulate basidiospores, and the presence of gloeoplerous hyphae in context and growing in pure forest of . is characterized by smaller pores (3-4 per mm), the presence of gloeoplerous hyphae in pileipellis, and the growth in forests of . Phylogenetically, the two new species are grouped in two independent lineages nested in . In addition, one sample from Northeast China is temporarily treated as sp. 1 because of the single sample; another Chinese sample from SW China is sister to in phylogeny, and it is treated as B.cf.grisea because the morphological difference between B.cf.grisea and is indistinct. Furthermore, the main characteristics of species are listed, and a key to accepted species of is provided.
基于形态学、生态学以及通过内转录间隔区（ITS）和核糖体RNA基因大亚基（nLSU）进行的系统发育分析，在中国西南部描述并图示了两种新的[物种名称]，即[物种名称1]和[物种名称2]。[物种名称1]的特征为担子果大（直径可达18厘米），担孢子具油滴，菌肉中有具油滴的菌丝，生长在[某种植物]的纯林中。[物种名称2]的特征为菌孔较小（每毫米3 - 4个），菌盖表皮中有具油滴的菌丝，生长在[另一种植物]的森林中。在系统发育上，这两个新物种被归入嵌套在[某个属]中的两个独立分支。此外，来自中国东北的一个样本因仅有单个样本而暂被视为[物种名称3] sp. 1；另一个来自中国西南部的中国样本在系统发育上是[某个物种]的姐妹种，由于[疑似灰[物种名称4]]与[某个物种]之间的形态差异不明显，故将其视为疑似灰[物种名称4]。此外，列出了[该属]物种的主要特征，并提供了[该属]已接受物种的检索表。
