Diversity of medicinal, edible, and poisonus fungi located on the deadwood of beech

Forest management has an essential impact on the growth of medicinal, edible, and poisonous wood-inhabiting fungi. Identification and cultivation of some edible fungi play an important role in supplying food needs and knowing medicinal fungi can be important for maintaining health and treating many diseases. The purpose of this study was to identify of wood-inhabiting fungi on deadwood of Fagus orientalis trees in the Darabkola forests. Also, we categorized these fungi into medical, edible, and poisonous groups, and present the volume of deadwood in these forests. After conducting preliminary field survey, sampling was done from deadwood. Identification of fungi in the fungal laboratory through morphology and extraction of ITS nrDNA region was done and sequenced using ITS1 and ITS4 primers and corrected with Bio Edit software and analyzed in NCBI. The results showed that 37 fungi species were identified, and among which, 70% had medicinal and economic values, 22% had edible value, and 8% had toxicity characteristic. A total of 15 deadwoods were studied, and 40 taxons of edible, medicinal, and poisonous were identified. Also, most of the species on deadwoods were found to be Trametes versicolor, Lenzites betulinus, Daldinia concentrica, Pleurotus ostreatus, Ganoderma lucidum, and Fomes fomentarius, respectively. In conclusion, in order to manage the deadwood in a forest ecosystem for increasing the diversity of medical and edible fungi, it is suggested that to preserve the deadwood
