根据形态学证据和系统发育分析，本文描述了三个新种。白盖红菇的菌盖中心为黄红色至红棕色，边缘为黄白色至红白色，有时有裂纹，菌柄为红白色至淡粉色。红色红菇（Russula roseola）的特征是其菌盖中心为红白色至宝石红色，边缘为粉红色至玫瑰色，贴生于稍下延的片层，片层不等长，菌柄为红白色至粉红色，偶尔有三细胞的毛囊。亚血红菇（Russula subsanguinaria）的形态特征是菌盖中心为红棕色至深棕色，边缘为红橙子至棕红色，边缘有条纹，柄为红白色至粉红色，基部膨大，担孢子上有中等距离至密集的淀粉样疣，在SV中，子实膜囊变为红黑色。本研究基于ITS序列和28 S-RPB 1-RPB 2-mtSSU数据集进行系统发育分析。详细的形态特征和系统发育分析表明，这3个新种均属于红菇属（Russula subg.）我叫罗秀拉
Three new species are described and illustrated here based on morphological evidence and phylogenetic analysis from China. Russula leucomarginata is recognized by a yellowish red to reddish brown pileus center, a yellowish white to reddish white and sometimes cracked margin, and a reddish white to pastel pink stipe. Russula roseola is characterized by its reddish white to ruby red pileus center, pink to rose margin, adnate to slightly decurrent lamellae with unequal-length lamellulae, reddish white to pink stipe, and occasionally three-celled pileocystidia. Russula subsanguinaria is morphologically characterized by a reddish brown to dark brown pileus center, a reddish orange to brownish red margin with striation, a reddish white to pink stipe with an expanded base, basidiospores with moderately distant to dense amyloid warts, and hymenial cystidia turning to reddish black in SV. In this study, we performed phylogenetic analysis based on ITS sequence and 28S-RPB1-RPB2-mtSSU datasets. Detailed morphological features and phylogenetic analysis indicate that these three new species belong to Russula subg. Russula.
