Phytomonitoring including mycological studies with information about plant pathogens, etc., is required to develop strategic directions for maintaining green spaces in urban agglomeration. Mycological analysis of the aerial part and roots of urban tree plants can be used to determine the composition and structures of microbial-plant associations in visually healthy and affected plants. The relevance of these works is due to rapid development of diseases and pests and their active distribution in close proximity to city residents. In coniferous and deciduous plants with symptomatic lesions ( Picea abies (L.) H. Karst., Pinus spp., Quercus robur L., Tilia spp.), the species diversity of micromycetes in the phylloplane and rhizosphere decreased by 21–38% compared to visually healthy plants. It was suggested using the following micromycetes as marker organisms for assessing the soil fungistasis of artificial bicenoses and the state of coniferous trees: D icoccum sp., Fusarium moniliforme J. Sheld., Fusarium culmorum . Perennial urban plants require improvement of the above-ground part using foliar fertilizers and phytostimulants, bioprotection tools, humates, mycorrhizal preparations, destructors of organic compounds of roots and adjacent lawns. The prospects of phytomonitoring of old-growing trees were emphasized. Reconstruction and enhancement of their resistance to aggressive environments require complex works.
