Abstract
Russula, a prominent genus of ectomycorrhizal fungi, is notably abundant and diverse in China. We present here the findings from studies on various Chinese Russula collections. Two notable species within subg. Heterophyllinae, namely Russula leucoviridis and R. subswatica, were described and illustrated based on comprehensive morphological characteristics and molecular evidence. Morphologically, Russula leucoviridis is characterized by its small to medium-sized basidiomata with a cuticle that cracks and breaks into small green patches near the center after mature, a pastel green to green pileus center with light yellow spots, and a white to greenish white pileus margin; whereas R. subswatica is distinguished by an infundibuliform pileus with a deeply depressed center after mature, a light orange to grayish orange pileus center, and a yellowish white to light orange margin with a purplish to purplish-black hue, and a white to yellowish white stipe that exhibits a purplish hue at the junction with the pileus. The phylogenetic analyses were constructed using a combined dataset of ITS, nrLSU, RPB2 and mtSSU. Relying on both morphological characteristics and multigene phylogeny, the former species is classified within subsect. Virescentinae, while the latter is affiliated with subsect. Griseinae. In this study, we contribute new data on infrageneric phylogenetic relations and enrich the species diversity of Subg. Heterophyllinae in China.
