Abstract: A field investigation on the wild economic macro-fungi was conducted at 14 locations in the Bijie District of Guizhou Province. A total of 437 fungal specimen
s were collected and identified, with 100 species (varieties and forms) of 52 genera and 31 families newly discovered, and 187 species of 86 genera of 44 families retraced from literatures. Family Russulaceae had the largest species number (34), occupying 18.2% of the total, followed by Polyporaceae (17 species and 9.1%), and Agaricaceae (14 species and 7.5%) and Boletaceae (14 species and 7.5%). Among the economic fungi, 141 taxa were edible, and 46 taxa were medical. Ectomycorrhizal fungi reached 96 species, occupying 51.3% of the total, and the rests were saprotrophic fungi (88 species), parasitic fungi (2 species), and entomogenous fungi (1 species), indicating that in the District, ectomycorrhizal fungi covered more than half of the total, being of significance in stabilizing local forest ecosystems. The analysis on the distribution patterns of the fungi at different altitudes and in different forest types and seasons showed that the species number decreased with increasing altitude but kept stable when the altitude reached a certain level, fungal growth was most prosperous in July-August and September-October, and the ranking of the species number in different forest types was Pinus armandii and Castanea seguinii mixed forest > Camellia spp. + Metasequoia glyptostroboides + Pinus yunnanensis mixed forest > Pinus armandii forest > Rhododendron natural forest. In contrast with the rather rich economic fungi in Bijie, only 16 species (8.6% of the total) were found in the local markets, suggesting that the exploitation and unitization potential of wild mushrooms in the District was still to be excavated.
