Diversity of Cantharellus (Cantharellales, Basidiomycota) in China with Description of Some New Species and New Records

Abstract

Cantharellus is a well-known genus of edible mushrooms, belonging to the family Hyd-naceae in the class Agaricomycetes. In this study, a phylogenetic overview of Cantharellus subg. Cinnabarinus and C. subg. Parvocantharellus in China is carried out with the description of four new species. Species description are based on morphological characters of basidiomata and phylogenetic analyses of multi-locus dataset of 28S + tef 1 + rpb2. Among the new species, two species, C. chrysan-thus and C. sinocinnabarinus, belong to C. subg. Cinnabarinus and two new species, C. convexus and C. neopersicinus, belong to C. subg. Parvocantharellus. Species delimitation characters of the new taxa are compared with closely related species. In addition, three new records of Cantharellus are reported for China: C. albovenosus and C. citrinus of subg. Cinnabarinus and C. koreanus of subg. Parvocantharellus. A key to the species of subg. Cinnabarinus in China was provided.
