First mycological investigation of poplar plantings was carried out on the territory of City of Blagoveshchensk; the species composition of wood-destroying fungi (Basidiomycota section) and their distribution in plantings were revealed. The results of many years of research on the state of poplar plantations have shown that the rotten diseases of this breed take second place after necrosis-cancerous diseases. In total, 45 species of fungi belonging to 34 genera and 17 families were identified. Most of identified basidiomycetes relate towidespreadand tolerant species with a wideecological amplitude. Several species are regarded as rare in the region (Cellulariella warnieri and Oxyporus populinus). The species Hericium coralloides is included in the Red Book of the Amur Region. Study of the fungi distribution by their substrate types revealed that 11 species lived on poplar living trees, 26 species grew on drying ones and almost all of the species found on poplar (41) destroy dead wood (stumps, dead trunks, deadwood and brushwood). The aggressive pathogens of poplar include two species of xylotrophs causing stem rot: Sarcodontia spumea and Hemipholiota populnea. However, mostly poplar plantations is attacked by saprotrophic fungi species, settling on weakened and damaged trees, including after the pollard pruning: Bjerkandera adusta, Ganoderma applanatum, Trametes trogii, Fomes fomentarius. Based on research result, where Thelephora palmata was caused decay of young poplar shoots, using them as a support, this species should be considered is pathogenic, but not wood-destroying. In the distribution and abundance of xylotrophic fungi, the age of plantations is of no small importance (the older the plantation, the more often and more abundant there are fungi). Regular pruning of crowns leads to the destruction of many trees due to the lack of full phytosanitary treatment. Phytopathological monitoring of green plantings revealed that old-aged trees in community of Populus balsamifera s.l., P. nigra and P. maximowiczi. mostly affected by fungi in ordinary street plantings, which are exposed to negative impact of the urban environment According to the state and fungal diseases resistance for greening at Blagoveshchensk is recommended to expand the plantings of P. alba and P. simonii. For the prevention of rotten poplar diseases in the city Blagoveshchensk, it is necessary to strengthen the complex of protective measures for sanitary pruning of trees and regularly rejuvenate urban plantings. When landscaping, it is recommended to avoid monocultural linear plantings of poplar and alternate them with other hardwoods to prevent the dispersal of pathogenic fungi.
