The features of the species composition of microscopic fungi in the root system and rhizosphere soil of woody plants in connection with the level of soil contamination have not been studied sufficiently. This article presents the results of studying the species composition of fungi in the root system and soil of three species of woodyplants (Acer negundo L., Acer platanoides L., and Betula pendula Roth.) growing in urban plantations of various ecological categories with different levels of heavy metal soil contamination. The study was carried out in a large industrial center of the Urals region, Izhevsk. When studying the species composition of fungi, microscopyand molecular genetic analysis were used. Isolates of endotrophic fungi from the root system of plants were isolated, and systematic membership was determined by molecular genetic analysis. The results showed that in soils with a high level of contamination, the DNA of endotrophic mycorrhiza-forming fungi was found in theroots of woody plants in a good living state. Keywords: fungi, heavy metals, plantations, urban environment, resistance
