Abstract: Yunnan is an area rich in wild commercial fungi resources, namely, fungi sold in markets. Much attention has been paid to fungal resources in the past. However, comprehensive investigation and studies on the resources were wanting. Through investigation, collection and identification of species, the geographical distribution patterns, seasonal changes and ranking based on the trade volume and the economic value of the resources were documented continuously from 1997 to 2001. In total, 207 species (including varieties and forms) belonging to 64 genera are recognized, showing high diversity and high endemicity. Among the species, those of the genera Boletus, Tricholoma, Termitomyces, Thelephora, Russula, Lactarius, and Ramaria are main commercial fungi. Despite artificial selection, commercial fungi show obvious geographical distribution patterns: southern Yunnan is rich in tropical species and northwestern Yunnan is rich in temperate alpine and subalpine species. Central and southwestern Yunnan fungal communities display subtropical and temperate characters. Each area possesses its own typical species and they are related by some transitional ones. We ranked the commercial fungi species in the order of trade volume. Those of grade I and II are the dominant species. Almost 90% of the commercial fungi are edible and about 5% are medicinal, while 7% are poisonous. The economic value of each species is also provided.
