This study of beetles attracted by a sawdust substrate overgrown with mycelium of rare species of wood-decay fungi was aimed to assess (1) ecological groups of the beetles caught in traps with such a substrate; (2) species composition of beetle communities attracted to sawdust substrate with the selected wood-decay fungi. To determine which tree-fun- gus beetles are associated with selected species of wood-decay fungi, we caught beetles in traps with sawdust substrate overgrown by the mycelium of seven species of wood-decay fungi: Bondarzewia mesenterica (Schaeff.) Kreisel, Fistulina hepatica (Schaeff.) With., Fomitopsis rosea (Alb. Schwein.) P. Karst., Grifola frondosa (Dicks.) Gray, Hericium alpestre Pers., H. coralloides (Scop.) Pers. and Meripilus giganteus (Pers.) P. Karst. The research was carried out in central Poland, at the Forest Experimental Station in Rogów. One research season (April–October) yielded a total catch of 133 beetle species associated with wood-decay fungi, including 60 mycetobiontic species. The most abundant species of beetles were: Trixagus carinifrons (Bonvouloir, 1859), Cortinicara gibbosa (Herbst, 1793), Dienerella ruficollis (Marsham, 1802), Rhizophagus bipustulatus (Fabricius, 1792), and Aulonothroscus brevicollis (Bonvouloir, 1859). Two autonomous clusters of tree-fungus beetles were distinguished in the collected material: beetles associated with brown rot and beetles associated with white rot. The sawdust substrates with mycelium of wood-decay fungi, used in traps, attract mycetophilic and mycetobiontic beetles.
