Abstract: Morphological observation and molecular biological identification were conducted on a wild strain of Pholiota spp.Additionally，the optimal temperature and pH value for its growth were screened，its ligninase activity was measured，artificial cultivation and domestication were carried out，and its nutritional components were analyzed.The results indicated that this wild Pholiota strain was identified as Pholiota adiposa.Its optimal growth temperature was 27 ℃，and the optimal growth pH value was 5.0.It exhibited strong ligninase activity. The strain could fully colonize the cultivation bag within 45 days.Primordia appeared 6 days after opening the bag，and it could produce 5 flushes of fruiting bodies.Through artificial cultivation，fruiting bodies were successfully obtained.The protein content in the fruiting bodies of P.adiposa could reach 300.0 g/kg，with high and relatively comprehensive amino acid content.The crude fiber content was 78.0 g/kg，and the selenium content was 0.150 mg/kg.The wild P.adiposa obtained has excellent cultivation characteristics and rich nutritional components. It can be used as a new high⁃quality germplasm resource of edible and medicinal fungi.
