Russula griseocarnosa is an important ectomycorrhizal edible fungus whose economic and nutritional value are both high. To better understand which abiotic biotic factors affect the growth of R. griseocarnosa, this study examined mycosphere soil growing in five sites. The fungal communities from sites Fujian, Guangxi, Yunnan Provinces were sequenced by Illumina MiSeq technology, their community structure comprehensively analyzed combination with a suite physicochemical properties. results revealed significantly greater levels available potassium (AK), nitrogen (AN), phosphorus (AP) than bulk soil, that prefers acidic Penicillium, Trichoderma, Talaromyces, Mortierella, Tolypocladium, Chloridium, Oidiodendron, Umbelopsis being main dominant taxa. Different geographical had different indicator genera, similarity decreased increasing distance among them. Soil pH was major factor influencing communities. Management strategies such as nitrogen, potassium, mixed fertilizer, fertilizer can promote conservation sustainable utilization griseocarnosa.
