[Effect of heavy metal ions on the soil mycobiota in Kryvyĭ Rih region].

Ecological-taxonomic analysis of mycobiota from heavy metal polluted soils in Kryvyi Rig town and its residential suburbs are presented in this study The mycobiota consists of45 filamentous species (127 strains) belonging to 28 genera from 3 divisions. Among them Myrothecium leucotrichum was described as a new species for Ukrainian mycobiota while Absidia cylindrospora and Gongronella butleri as rare species. Paecilomyces lilacinus and P. marquandii dominated in the soils near the factory Kryvorizhstal and South Ore Mining and Processing Enterprises. In these soils, Mycelia sterilia (white and dark) and dark-colored micromycetes occurred with a high frequency (up to 30%). Results obtained allow us to conlude that ecological conditions in Kryvyi Rig town are unfavourable.
