Abstract
Shanxi Province, located in northern China, characterized by a warm-temperate monsoon climate, complex mountainous topography, and vegetation dominated by trees of Fagaceae and Pinaceae, provides diverse habitats for Russula diversity. Recent investigations on macrofungi in this region revealed nine new Russula species based on integrated morphological and multi-locus phylogenetic analyses (ITS, nrLSU, rpb2, tef1), which are described and illustrated in this paper. These new taxa are classified into three subgenera of Russula: one species of subgen. Brevipes, four of subgen. Heterophyllidia, four of subgen. Russula. This work enhances the understanding of Russula resources in China's temperate zone.
