摘　　要：红菇属乳菇状亚组Russula subsect.Lactarioideae是一个形态特征较明显的类群,亚属内部分种类被认为是复合种。在对我国红菇属乳菇状亚组进行的分类学研究中,发现了3个新种:丝黄红菇Russula byssina、奶油色红菇R.cremicolor和白果红菇R.leucocarpa,均产自我国贵州省,生于针叶林下。基于形态详细观察和ITS序列系统发育分析的结果对其进行详细描述,对新种和近缘种间差异进行了比较和讨论,提供了新种与乳菇状亚组和淡孢亚组R.subsect.Pallidosporinae中近缘种的物种检索表。分子系统学结果显示奶油色红菇与Delica-Brevipes分支亲缘关系较近,白果红菇和丝黄红菇隶属于两个独立分支。Three new species of Russula subsect. Lactarioideae, Russula byssina, R.cremicolor and R.leucocarpa collected from Guizhou Province grown under coniferous forest are described and illustrated based on morphological observation and ITS phylogenetic analyses. A key to these new species and closely related taxa in subsect. Lactarioideae and subsect. Pallidosporinae is provided. Phylogenic topologies show that R.cremicolor has a close relationship with Brevipes-Delica clade;R.byssina and R.leucocarpa are members of two independent clades.
