Abstract:

Aims: This study conducted field investigations and specimen collection in order to systematically clarify the species composition, taxonomic characteristics, resource value and endangered status of the macrofungi in the Jiulian Mountain Nature Reserve. The studies will provide fundamental data support for further investigations of macrofungi, ecological protection and resource utilization in the area. 

Methods: 737 macrofungal specimens were obtained in total from 2023 to 2025 in Jiulian Mountain using line transect and random survey methods. Species identification was conducted based on molecular phylogenetic evidence and morphological characteristics. 

Results: A total of 215 species of macrofungi were identified, and they belong to 2 phyla, 6 classes, 17 orders, 64 families, 123 genera. Among them, 3 classes, 4 orders, 7 families, 8 genera and 11 species are ascomycetes, while 3 classes, 13 orders, 57 families, 115 genera and 204 species are basidiomycetes. Six species are records new to Jiangxi. The dominant families include Polyporaceae, Omphalotaceae, Psathyrellaceae and Russulaceae, with 61 species, accounting for 28.37% of the total species. The nine dominant genera contained Gymnopus, Pluteus, Russula and Mycena, etc, which comprise 56 species accounting for 26.05% of all the known species. The subtropical evergreen broad-leaved forest is the dominant vegetation types where macrofungi grow, and the main nutritional types is lignicolous. The resource evaluation showed that 29 species were edible fungi, 32 species medicinal fungi, 33 species of edible-medicinal fungi and 33 species poisonous fungi. Threat status analysis revealed that one species was categorized as nearly threatened, merely accounting for 0.46% of the total known species, and no vulnerable, endangered or critically endangered species were recognized.
