ABSTRACT. As a result of many years of research in the Chelyabinskaya Oblast of Russia, the Southern Urals, the species composition, ecological and trophic structure, and dynamics of the Coleoptera community, associated with the tinder Lenzites betulinus (Polyporaceae) were studied. 37 beetle species from 14 families, Cis setiger, C. hispidus, Sulcacis fronticornis, S. nitidus (Ciidae), Tritoma subbasalis (Erotylidae) and Orchesia fusiformis (Melandryidae), are registered as inhabitants of the dead fruit bodies of the fungus, playing significant role in their decomposition. Eight nonspecialized mycetophagous beetle species, Scaphisoma agaricinum, S. inopinatum, Atheta boleticola, Gyrophaena bihamata (Staphylinidae), Enicmus fungicola, E. rugosus, Latridius consimilis and L. hirtus (Latridiidae) are recorded from living fungus bodies. Association of Thymalus oblongus (Trogossitidae) with L. betulinus is registered for the Southern Urals for the first time. It is shown, that mycelial layer is invaded by beetle larvae of Cerylon deplanatum, C. fagi (Cerylonidae), Rhizophagus bipustulatus, Rh. dispar, Rh. parvulus (Monotomidae), Bitoma crenata (Colydiidae), Melandrya dubia (Melandryidae), and Upis ceramboides (Tenebrionidae), their adult sometimes occurring on fungus fruit bodies. No specific residents of the L. betulinus basidioms have been revealed.

KEY WORDS: xylotrophic basidiomycetes, Lenzites betulinus, Coleoptera, microsuccessions, mycetophilic community.
