Abstract14 species of myrcomycetes of the class Leotiomycetes have been identified on decorative trees in the southern part of Uzbekistan. Species of the genera Uncinula, Phyllactinia, Leveillula, Microsphaera, Erysiphe are obligate parasites, and Marssonina, Melasmia, Rhytisma are considered facultative parasites and causative agents of dangerous diseases in trees.
