Macrofungal diversity and its characteristics in the western priority area of Wuling Mountains
A comprehensive investigation and evaluation of the macrofungi in the western priority area of the Wuling Mountains was conducted,covering six regions including Chishui,Xishui,Wuchuan,Yinjiang,Jiangkou,and Nanchuan under jurisdiction of Chongqing.Species composition,distribution of dominant genera and species,and the current biodiversity status were analyzed.In total,1 148 species of macrofungi were recognised,belonging to 2 phyla,13 classes,26 orders,91 families,and 304 genera.Among them,784 species were newly recorded in the western priority area of the Wuling Mountains.The dominant families were Russulaceae,Polyporaceae,Boletaceae,Agaricaceae,etc.,which accounted for 81.27%of the total species;while the dominant genera were Russula,Lactarius,Amanita,Marasmius,Mycena,etc.,accounting for 48.69%of the total species.The world-wide distributed and boreal-temperate distributed species were the most common in this area,with 763 and 230 species respectively,accounting for 66.46%and 20.03%of the total species.There were 93 species endemic to China,accounting for 8.1%of the total species.There were 29 species that were considered threatened,vulnerable,or near-threatened,accounting for 2.52%of the total species.This study provides reference for protection and management of ecological environment and biodiversity in the western priority area of Wuling Mountains.
