The role of aphyllophoroid macromycetes as indicators of forest ecosystem disruption and reducers of biomass accumulation

Aphyllophoroid macromycetes are a key link in natural and artificial biocenoses, particular, forest ecosystems. Their peculiarity is due to the variety of morphological forms ability colonise various substrates. The establishment fundamental issues biotic organisation this group fungi, which considers both their specific features integration into general ecological patterns, necessary basis for further research, protection, practical use (in when indicating monitoring state biocenoses). purpose study was establish species composition, taxonomic structure, distribution (by mycohorizons) aphyllophoroid stands Zhytomyr Polissia. In course study, classical phytopathological forestry-inventory (biometric) analysis methods were used. Special mycology, mycoindication, also used terms identifying examining macromycetes. Mycoflora Polissia has 27 belonging 17 families, 8 orders Agaricomycetes class Basidiomycota division typical European temperate zone. systematic component under represented by following orders: Polyporales (40.7% total number), Hymenochaetales (18.5%), Agaricales (14.8%), Russulales (11.2%), Cantharellales, Thelephorales, Auriculariales, Gomphales (3.7% each). Analysis food structure shows that most mycoflora complex saproxilotrophic species, lesser extent parasite fungus (for example, Inonotus hispidus, Phellinus robustus, Heterobasidion annosum) humus saprotrophs (Thelephora terrestris) noted. mycohorizons identifies more than 70% all finds located subsurface mycohorizon, root mycohorizon characterised smallest number There gradual decrease diversity edge areas, demonstrates fundamentally different stages ecosystem degradation processes. investigation historical relationships between woody plant macromycetes, act as biological indicators ecosystems, will allow forming “maps disruption integrity biocenoses” sanitary risks, should be implemented practice protection
