中国贵州省贵阳市大型真菌编目OA

Located in the central mountainous and hilly region of the Guizhou Plateau at the watershed between the Yangtze and Pearl Rivers,Guiyang features a mild and humid subtropical climate.With a forest coverage rate of up to 55%,it provides an ideal habitat for macrofungi,while a systematic inventory of its macrofungal species diversity is lacking for a long time.Based on specimen data collected by our research team from 2019 to 2025,a comprehensive checklist of macrofungi in Guiyang is compiled.The results reveal a total of 578 macrofungal species in the area,including approximately 250 newly recorded species.These taxa are distributed in 2 phyla,9 classes,24 orders,103 families,and 262 genera,comprising 32 species of Ascomycota and 546 species of Basidiomycota.The dominant orders are Agaricales,Polyporales,and Russulales.The dominant families include Russulaceae,Polyporaceae,Agaricaceae,Amanitaceae,Omphalotaceae,Boletaceae,and Psathyrellaceae,which account for 6.80%of the total families,with the sum of species accounting for 35.99%of the total macrofungal species recorded.The dominant genera are Russula,Amanita,Agaricus,Lactarius,and Marasmius,accounting for 1.90%of the total genera,with the sum of spcecies accounting for 15.74%of the total macrofungal species recorded.The world-wide distributed and boreal-temperate distributed species were the most common in this area,with 405 and 106 species respectively,accounting for 70.07%and 18.34%of the total species.Resource assessment indicated that there were 113 edible species,60 medicinal species,37 species concurrently edible and medicinal,and 51 poisonous species.Threatened status assessment identified three vulnerable(VU)species,and four near threatened(NT)species,accounting for 1.19%of all known species.Sixty-seven species are endemic to China.This checklist elucidates the composition,resource status,and threat status of the species of macrofungi in Guiyang,laying a foundation for the future development and utilization of these resources.
