Diversity and resource evaluation of macrofungi in Guanshan National Nature Reserve of Jiangxi Province,East China
摘要
Abstract
The macrofungal biodiversity in Guanshan National Nature Reserve of Jiangxi Province,a vital component of the Jiuling Mountains,remains insufficiently understood.A comprehensive inventory of macrofungal resources in the reserve based on systematic field surveys conducted from 2022 to 2023 was carried out.In total,810 specimens were collected during the field surveys.Based on morphological examination in combination with molecular phylogenetic analysis,251 macrofungal species were identified.These taxa are distributed in 2 phyla,6 classes,19 orders,76 families and 143 genera,comprising 222 basidiomycetes(88.45%)and 29 ascomycetes(11.55%).Notably,12 species represent new records for China.The dominant families are Polyporaceae,Russulaceae,Agaricaceae,Boletaceae,Omphalotaceae and Marasmiaceae,with the sum of species accounting for 40.24%of the total number of macrofungal species;the dominant genera include Russula,Marasmius,Collybiopsis,Ganoderma,Trametes and Ophiocordyceps,with the sum of species accounting for 20.32%of the total number of macrofungal species.The economic value evaluation showed that there were 52 edible species,58 medicinal species,43 mycorrhizal species,34 poisonous species and 135 wood-decaying species.Analysis of floristic geographical elements at the generic level indicated a predominance of cosmopolitan taxa,which accounted for 71.33%of the total number of macrofungal genera.The coexistence of north temperate elements(13.99%)and tropical elements(9.79%)reflected the transitional characteristics of the mid-subtropical transitional flora.Regarding the assessment of threat status,two species were categorized as near threatened(NT),while data deficient(DD)species accounted for 25.77%of the total.Ten species were identified as endemic to China.This study provides the primary systematic documentation of the species diversity,floral composition,and resource status of macrofungi in the Guanshan National Nature Reserve,establishing a critical scientific foundation for the conservation and sustainable utilization of the regional fungal resource.关键词
