Specifics of formation the micromycetes complex in soils of island flood lands at ilych river

The complex of microscopic fungi in soils of the Ilych River (a tributary of the Pechora River) island flood-lands has been studied. 90 species of micromycetes of 26 genera were identified. Most representative were the genera of Penicillium, Mortierella, Aspergillus, and Trichoderma. Some species of micromycetes were first identified for flood soils of middle taiga plain rivers. Among the studied biotopes (towpath→ meadow → deciduous forest → coniferous forest), the highest alpha-diversity, number of spores, biomass of micromycetes and longest mycelium were found out for soil micromycetes of deciduous forest. In meadow coenoses, fungal mycelium mainly concentrated in mineral (humus-accumulative – A1) horizons of alluvial soils whereas in forests it preferred organic (forest litters – A0) soil horizons.
