云南文山州大型真菌多样性及资源评价OA

Wenshan Prefecture in Yunnan is located in the southeastern monsoon broadleaf forest biodiversity conservation priority area of southeastern Karst regions.Its complex terrain and diverse climate provide an excellent environment for the growth and development of macrofungi.The diversity,floristic composition,resource value,and endangered status of macrofungi in Wenshan Prefecture were systematically investigated through field collection,morphological identification,and molecular biological methods.A total of 303 species of macrofungi was identified,belonging to 2 phyla,6 classes,19 orders,68 families,and 160 genera,including 18 species of ascomycetes and 285 species of basidiomycetes.The dominant families were Russulaceae,Boletaceae,and Polyporaceae,while the dominant genera included Russula,Amanita,and Lactarius.Analysis of floristic geography revealed that Cosmopolitan(51.82%of the total species),Pantropical(23.64%),and North Temperate(20.00%)elements were dominant,demonstrating significant subtropical floristic characteristics.Resource assessment indicated that 140 species possess fairly high economic value,including 104 edible species,67 medicinal species,45 species with both edible and medicinal uses,and 39 poisonous species.Threatened status assessment identified one vulnerable(VU)species(Thelephora ganbajun),and one near threatened(NT)species(Artomyces pyxidatus).Fifteen species are endemic to China.The findings demonstrate the diversity and resource potential of macrofungi in Wenshan Prefecture,providing a scientific basis for the conservation and sustainable utilization of fungal resources,and the construction of ecological security barriers in this region.
