, one of the main subgenus of (Russulaceae, Russulales), is both ecologically and economically important. Although many studies have focused on subgenus in China, the diversity, taxonomy, and molecular phylogeny still remained incompletely understood. In the present study, two new species, and , and two known taxa, and were described based on morphology and molecular phylogenetic analyses of ITS and 28S DNA sequences with new collections of subgenus from southern China. Both morphological and phylogenetic analyses consistently confirmed that and belong to the subsect. , and come under subsect. , and is synonymized with .
作为红菇科（Russulaceae）、红菇目（Russulales）的主要亚属之一，在生态和经济方面都很重要。尽管中国有许多研究聚焦于该亚属，但在多样性、分类学以及分子系统发育方面仍未被完全理解。在本研究中，基于对来自中国南方该亚属新采集样本的ITS和28S DNA序列进行形态学和分子系统发育分析，描述了两个新物种，即[物种名1]和[物种名2]，以及两个已知分类单元，即[分类单元名1]和[分类单元名2]。形态学和系统发育分析均一致证实，[物种名1]和[物种名2]属于[亚组名1]亚组，[分类单元名1]和[分类单元名2]隶属于[亚组名2]亚组，并且[物种名3]与[物种名4]同义。
