Ascomycetous Fungi (Teleomorphs) on Trees and Shrubsin the Suburban Parks of St. Petersburg
Data on 75 species of ascomycetous micromycetes in the stage of teleomorph, revealed in the parks of the southern suburbs of St. Petersburg, are reported. Frequently observed species, as well as rare and interesting species, including parasitic and saprotrophic fungi are noted. Species of the genera Diaporthe, Diatrypella, Valsa were most common. Among the rare and interesting species were Caudospora taleola, Splanchosporaampullacea, Biscogniauxia repanda, Chlorociboria aeruginascens. The relationship of some species with their anamorphic stages was established. However, most of the detected Ascomycetes were saprotrophs developing on dry parts of plants or on plant remains. Pathogenic complexes of microscopic fungi on trees and shrubs have been identified. They include ascomycetous fungi in teleomorphic and anamorphic stages.
