Abstract: Objective: In order to investigate the macrofungal species resources in Cangshan mountain, to discuss the relationship between different elevations, vegetation types and macrofungal diversity, and propose suggestions for reasonable protection and
utilization. Methods: The collected samples were analyzed by random sampling and line transect investigations, and identified based on the morphological characteristics and molecular sequence data. Subsequently, the species composition and geographical fauna characteristics were figured out. Results: 2 490 specimens of macrofungi were collected in Cangshan mountain, a total of 400 species were identified, belonging to 147 genera, 59 families, 18 orders, and 6 classes, including one new species Geastrum suae. There were 9 predominant families （with species number ≥10）, 15.25% of the known families, including Boletaceae 54 species, Russulaceae 51 species, Amanitaceae 33 species, Agaricaceae 29 species, Inocybaceae 15 species, Cortinariaceae 14 species, Lycoperdaceae 13 species, Physalacriaceae 13 species and Hygrophoraceae 11 species, 233 species in total, accounted for 58.25% of the total species. There were 6 dominant genera （with species number ≥10）, accounted for 4.08% of the known genera, namely Russula 30 species,Amanita 30 species, Lactarius 19 species, Boletus16 species, Agaricus12 species, Inocybe 11 species, 118 species, accounted for 29.50% of the total species. The evaluation of macrofungal resources revealed that 187 species are edible, 56 have medicinal properties, 83 are poisonous, 124 remain unidentified as edible or toxins, and 28 are domesticated. The distribution of macrofungal species in Cangshan mountain follows a typical single-peak distribution pattern, and the number of species climb up and then decline with the increase of altitude. In Cangshan mountain, macrofungi species were most abundant in broad-leaved forests, followed by coniferous and broad-leaved mixed forests, and the least abundant in coniferous forests. Besides, a small number of macrofungi were found under shrubs, in natural or artificial grasslands, and in cultivated areas. Conclusion: The resources of macrofungi in Cangshan mountain are abundant and hold significant potential for development, utilization, and scientific research. It is necessary to effectively protect and scientifically and rationally utilize the macrofungal resources in Cangshan mountain.
