This article describes the characteristics of the beetle fauna – inhabitants of fruiting bodies and the mycelial layer of the true tinder fungus Fomes fomentarius L.: Fr. and are considers some important aspects of the ecology of mycetophilous beetles. Coleopteran population of fruiting bodies of the fungus in five districts of the Saratov region is 63%. Two species from the family Staphylinidae (Gyrophaena joyi Wendeler, 1924 and Scaphisoma boreale Lundblad, 1952) have been recorded on growing and / or spore bearing fruiting bodies. The complex of the main distructors is confined to dying fruiting bodies (20 species). The predominant group (61%) is Diaperis boleti (Linnaeus, 1758) (Tenebrionidae) and Erotylidae. At the trophic level, obligate mycetophages and mycetosaprophages prevail among coleopterans (95%). The most similar are the mycetophilous communities of the residential areas of Saratov and Engels (Kf = 0.7), extremely low similarity was noted for Saratov and Bazarno-Karabulak district (Kf = 0.1).
