摘　　要：本研究于2017–2021年在云南省文山地区进行了5次实地调查,共采集木腐真菌标本2923号。采用经典分类学方法开展了该地区采集标本的准确鉴定,并编制了木腐真菌完整名录。采用最大似然法、最大简约法和贝叶斯推理法对研究标本的ITS nrRNA基因序列构建系统发育树,剖析分类单元的聚类关系及物种间的系统发育关系。研究结果揭示该地区共报道木腐真菌104种,隶属于5目18科55属。其中多孔菌目为优势目(占总数的51.92%),多孔菌科为优势科(占总数的24.04%),木齿菌属为优势属(占总数的12.50%)。Five field surveys were carried out in Wenshan area,Yunnan Province,China during 2017–2021,and 2923 specimens of wood-decaying fungi were collected.A checklist of wood-decaying fungi with their hosts and substrates is given.The taxa were identified in the light of their morphology and molecular evidence.The sequences of ITS nrRNA gene region of the studied specimens were generated and the phylogenetic analyses were performed with the maximum likelihood,maximum parsimony and Bayesian inference methods.The paper summarizes the obtained results of investigation on the wood-decaying fungi of this area,consisting of 104 species belonging to 55 genera,18 families and 5 orders.Polyporales is the dominant order(51.92%of the total orders found in this area),and Polyporaceae is the dominant family(24.04%of the total)and Xylodon is the dominant genus(12.50%of the total).
