Hygrophorus subsect. Hygrophorus has been relatively well-studied in Europe and North America, but studies on the taxa in Asia, particularly in China, are still limited. In this study, phylogenetic overviews of genus Hygrophorus , based on the nuclear large subunit (LSU) ribosomal RNA gene and of subsect. Hygrophorus , based on the nuclear ribosomal internal transcribed spacer (ITS) regions were generated. Four new species, i.e. H. brunneodiscus , H. fuscopapillatus , H. glutiniceps and H. griseodiscus are described from southern China; and a rarely reported edible species H. hedrychii is described in detail, based upon the materials from north-eastern China. The main characteristics of the species under subsect. Hygrophorus worldwide are summarised in a table.
