Abstract
The article considers the species composition of the Dothideomycetes and its structural characteristics in conditions of the National Natural Park «Biloberezhzhya Sviatoslava». The materials of the work were the original mycological collecting carried out within the mycological survey of this territory during 2007-2017, as well as the materials of the herbarium of the Institute of Botany named after M. Kholodny National Academy of Sciences of Ukraine (KW). Herbarium collection and identification of the samples were performed in accordance with the generally accepted methods of cameral processing of xylotrophic, herbotrophic and coprothrophic micromycetes. To establish the taxonomic affiliation of species, the method of light microscopy was applied. As a result of our research, a species diversity of ascolocular fungi (Dothideomycetes) has been established, which includes 30 species from 20 genera 16 families 6 orders 2 subclasses and groups of taxa of Incertae sedis. The characteristic features of the taxonomic structure of the investigated mycobiota are the predominance of representatives of the order of Pleosporales, the family Leptosphaeriaceae, the genus Leptosphaeria. Herbotrophs associated with herbaceous plants (representatives of the genera Leptosphaeria, Pleospora, Ophiobolus) predominate in the ecological structure of the identified species composition. The ascolocular fungi species are form consortium connections with 25 species of vascular plants from 23 genera of 12 families, with the largest number of micromycetes noted on plants of the Asteraceae. The greatest number of fungal consorts is associated whis Artemisia marschalliana Spreng. An annotated list of the Dothideomycetes of the National Natural Park «Biloberezhzhya Sviatoslava» is given.
