Generalized data on phytopathogenic micromycetes registered in trees and shrubs of Mariupol from 1992 to 2024 are presented for the first time. A total of 82 fungi species associated with 53 plant species was identified. 19 pathogen species are characterized by annual occurrence, high harmfulness and spread in urban plantings. Among them there are causative agents of powdery mildew, rust, leaf spots and scab, shoot burn and needle dieback. The complex of alien micromycetes includes 35 species (43 % of the total number of identified fungi). The overwhelming majority of them (91 %) are associated exclusively with introduced plants. It is for the first time in the territory of the Donetsk People’s Republic that the causative agent of powdery mildew in common cherry, namely Podosphaera sp. cf. cerasi was found – being presumably an alien pathogen.
