Abstract: The Xiangxidong forest park is a region with special natural geographical conditions and excellent ecological environment, located in Ankang city, Shaanxi province. Yet, little information is available on ectomycorrhizal fungal （ECMF） resources associated with various trees in this region. In this study, the ECMF resources in Xiangxidong forest park were investigated by the method of field survey, specimen collection and laboratory identification. In total, 16 ECMF species of eight families were identified, belonging to 8 families, including 4 species of Boletaceae, 3 species of Cortinariaceae, 2 species of Russulaceae, 2 species of Tricholomataceae, 2 species of Cantharellaceae, 1 species of Strobilomycetaceae, 1 species of Lycoperdaceae and 1 species of Sclerodermataceae. Among them, ECMF was most widely distributed in coniferous and broad-leaved mixed forests, accounting for 75.00%, 37.50% of fungi were found in coniferous forests, and 62.50% of fungi were found in broad-leaved forest. In the view of economic value, the fungi included 9 species of edible fungi（Excl. those who have been poisoned and those who have been safe to eat it）, 9 species of medicinal or anticarcinogenic fungi（including fungi that have medicinal and anti-cancer properties）, and 7 species of poisonous fungi（including fungi that toxic to them）. The ECMF resources in the Xiangxidong forest park are relatively abundant and have a good prospect for development and utilization.
