Abstract
The species diversity and distribution of discomycetes of the Getmanskyi National Nature Park (Getmanskyi NNP) (Okhtyrskyi district, Sumi region) have been studied. As a result of generalization of own data and analysis of published literature sources 63 species of discomycetes belonging to 36 genera, 19 families, 4 orders and two classes are given: Leotiomycetes - 25 species from 17 genera, Pezizomycetes - 38 species from 19 genera. Among the most numerous orders are Pezizales - 37 species and Helotiales - 13. The family spectrum is dominated by Ascobolaceae - 11 species, Pezizaceae - 6 species, Helotiaceae - 5 species, Ascodesmidaceae, Mollisiaceae, Pyronemataceae and Rhytismataceae. These dominating species make 62.3% of the total number of discomycetes registered in the study area. The article provides an annotated list of relevant species of fungi and associated host plants and nutrient substrates. On the territory of the Getmanskyi NNP the coprophilous discomycete Iodophanus verrucisporus (P.W. Graff) Kimbr., Luck-Allen & Cain was discovered for the first time in Ukraine. Among the registered species, the vast majority belong to the substrate groups of dung-inhabiting ascomycetes (26 species), xylophiles (14), edaphophiles (10) and phyllophiles (6). The prospects of further mycological research on the territory of the Getmanskyi NNP are shown, during which special attention should be paid to the study of certain ecological (bryophilic, pyrophilic, mycophilic, humic) and taxonomic (Helvellaceae, Hyaloscyphaceae, Morchellaceae, Orbiliaceae, Pezizaceae, Pyronemataceae, Tuberaceae) groups of discomycetes.
