Species composition of soil algae and cyanobacteria in the large industrial city of Magnitogorsk (Chelyabinsk region) studied. Flora of microscopic èdafofototrofs was characterized by low species diversity with a clear predominance of cyanobacteria. 15 species of cyanobacteria, 11 species of green algae, 5 diatoms, one species of yellow-green and eustigmatophyta algae was found. There were identified groups of the most common species, dominant and subdominant species. The highest incidence in the soils of the city had diatom algae Hantzschia amphioxys. Although species diversity was low, cyanobacterial-algal cenoses had significant species abundance. The complex dominant species included representatives of all phylums, with the exception of yellow-green algae. Selected leading taxonomic categories of èdafofototrofs of Magnitogorsk: division Cyanobacteria, class Cyanophyceae, orders Nostocales, Oscillatoriales and Chlamydomonadales, family Nostocaceae and Phormidiaceae, genus Nostoc. Qualitative and quantitative characteristics cyanobacterial-algal cenoses of different biotopes of the city depended on the nature of anthropogenic use and degree of disturbance of soil.
