Аннотация:This review presents an analysis of the results of mycological investigations of peat obtained by the authors and other Russian and foreign scientists. Highmoor peat, unlike lowmoor peat, is shown to contain great reserves of fungal biomass mainly represented by mycelium. The viability of the mycelium and spores is high in the upper peat horizons and does not exceed 50% in the ower ones. In highmoor peat, fungi that are capable of destroying the complex structural polymers composing up to 50% of the peat rarely occur. The analysis of the factors limiting the activity of fungi in the highmoor peatbogs showed that, in the upper layers,the main factor was the strength of the sphagnum cellular walls. In the lower layers, the significant oxygen def
icit and the accumulation of sphagnans, sphagnols, phenolcontaining compounds, and antioxidants that block the activity of hydrolytic and oxidizing enzymes are of great importance.
