The communities of fungi in the soil, rhizosphere, planosphere and roots of Trifolium pratense L. and Dactylis glomerata L. were examined in pure and mixed crops. The plants were cultivated for four years under mountain conditions . The formation of these communities and the changes taking place in them depending on the plants and the years of culture were examined. No species pathogenic for clover and cocksfoot were observed in these mined. No species pathogenic for clover and cocksfoot were observed in these communities.
