对来自中国南方的两个新种红菇 (Russula albolutea) 和红菇 (R. subpunicea) 进行了描述和说明。红菇的识别特征是边缘有长条纹的黄白色菌盖、带淡黄色的白色菌柄、球状至宽椭圆形的担孢子、主要为棍棒状和顶部通常钝并在磺香草醛中变成紫红色的子实膜孢子，以及主要由短的膨胀细胞链和末端细胞变薄组成的上菌盖。红菇的特征是边缘有条纹的粉红色至深粉色菌盖，球状至宽椭圆形的担孢子，有时连接形成网状疣和刺，主要为棍棒状的处女膜孢子，主要由末端细胞变薄的短膨胀细胞链组成的上皮囊，以及主要为棍棒状并在磺基香草醛。在本研究中，我们分别基于ITS序列和nrLSU-RPB2-mtSSU数据集进行系统发育分析。通过将详细的形态特征与多基因系统发育证据相结合，我们将新的分类单元归入红菇亚组。绿藻亚科。
Two new species from southern China, Russula albolutea and R. subpunicea, were described and illustrated. Russula albolutea is recognized by a yellowish white pileus with long striations at the margin, a white stipe with a yellowish tinge, globose to broadly ellipsoid basidiospores, hymenial cystidia that are mainly clavate and apically often obtuse and turn mauve in sulfovanillin, and a suprapellis mainly consisting of chains of short inflated cells with attenuated terminal cells. Russula subpunicea is characterized by a pinkish to dark pink pileus with striations at the margin, globose to broadly ellipsoid basidiospores with warts and spines sometimes joined to form a reticulum, hymenial cystidia that are mainly clavate, a suprapellis mainly composed of chains of short inflated cells with attenuated terminal cells, and pileocystidia that are mainly clavate and turn reddish in sulfovanillin. In this study, we respectively performed phylogenetic analysis based on the ITS sequence and nrLSU-RPB2-mtSSU dataset. By combining detailed morphological features with multigene phylogenetic evidence, we assigned the new taxa to Russula subsect. Virescentinae.
