Occurrence and abundance of microscopic fungi in floodplain forest soils

Occurrence of soil micromycctes was investigated in soils at four localitie s in floodplain forests with Salix (S-1-S-4) and at four localities in floo dplain forests with Populus (P-1-P-4) in the vicinity of Gabeikovo. The age category of forests were from 10 to 40 years. Thirty-one genera of microsc opic fungi were determined from Fluvi - eutric Gleysol and Eutric Fluvisol (FAO). The most frequent genera are: Penicillium, Trichoderma. Aspergillus, Aureobasidium, Verticillium, Humicola.
