Different saprophytic micromycetes were isolated from the humic horizon (H-A 02) of different types of forest soils (barren l and of reforested waste dumps, cambisol of spruce, birch, European mountain ash, and blue spruce forests) in several areas (at Most in the Krušné hory (Ore Mts.), Jizerské hory (Izera Mts.)). Besides the spectrum of common species of soil micromycetes (Penicillium spp., Humicola spp., Trichoderma spp., Paecilomyces spp., Scopulariopsis spp., Aureobasidium spp., Mucor spp., Absidia spp.), the fungus Micromucor ramannianus (Möller) Arx var. ramannianus (Mortierella ramanniana (Möller) Linneman, Mucor ramannianus Möller) was regularly isolated from all types of soils, except barren soils of was te dumps. The biological quality of forest soils in connection with other biological characteristics was evaluated in relation to the presence and quantity of this fungus in forest soils. Basic biological processes (basal and potential respiration, ammonification, nitrification) show an increased intensity in forest soils in which the proportion of Micromucorramannianus v. ramannianus was not present in the soil of the worst biological quality (lower values of biological soil parameters), e.g. in of was te dumps. It is a topic for discussion whe the r this fungus can also be an indicator of environmental pollution.
