Abstract: Identification of ectomycorrhizal (ECM) fungi in different ecosystems has major significance. In this research, to identity ECM fungi, we used two methods including the morphological method and the molecular method that is more precise. Basidiocarp collection of fungi associated with oak tree (Quercus brantii Lindl.) roots was carried out in the spring season 2016 and was identified by morphological and molecular methods. We also checked macroscopic and microscopic features and measured each structure using BioloMICS Measures software. To verify the morphological identification, the internal transcribed spacer (ITS) region was amplified by PCR using the primer pair ITS1/ITS4, and the sequences were analyzed. According to the morphological observations, the identified species were Amanita crocea, Boletus comptus, Tricholoma giganteum, and Inocybe rimosa. Besides, based on molecular techniques by comparing sequences, we identified five species out of the eight ones as A. crocea and other species as T. giganteum, I. rimosa and B. comptus. Both morphological and molecular methods are necessary for identifying ECM fungi associated with tree roots in the Zagros zone in the west of Iran.
