Essay

This thesis reports result of special study of aphyllophoroid fungi of Kyiv Plato. The species diversity, taxonomic, trophic and spatial composition, previously unknown distribution of fungal communities in different types of habitats of the studied area were investigated. Totally 221 species of aphyllophoroid fungi from 118 genera, 40 families, 11 orders of class Agaricomycetes (Basidiomycota) were detected. Of them, 72 speciesare new to the study area. In total, 52 species are new records for the Right Bank Forest-Steppe of Ukraine. 14 species were registered for the first time for the Right Bank of Ukraine. Hymenochaetopsis corrugata is reported for the first time for the plain part of Ukraine. Lentinellus ursinus is reported for the first time for Ukraine. Taxonomic analysis showed that orders Polyporales, Hymenochaetales and Russulales were dominated. Ten families were leading in terms of species richness: Polyporaceae, Meruliaceae, Hymenochaetaceae, Fomitopsidaceae, Gomphaceae, Schizoporaceae, Phanerochaetaceae, Corticiaceae, Peniophoracae, and Typhulaceae; in addition, 23 genera also were predominated, namely Ramaria, Peniophora, Trametes, Typhula, Lentinus, Stereum, Botryobasidium, Oxyporus, Ganoderma, Phlebia, Steccherinum, Phanerochaete, Antrodia, Ceriporia, Cerioporus, Clavulina, Hydnum, Hymenochaete, Inonotus, Vuilleminia, Phellinus, Postia, and Xylodon. As a rescibt of the analysis of the distribution of fungi by substrates 11 ecological-trophic groups were found, among which saprotrophs on wood decay of various sizes predominated (69.9 %). Most of species of aphyllophoroid fungi of Kyiv Plato participating in the decomposition of wood of the main forest-forming species. The greatest species richness of fungi investigated is found in subcontinental hornbeam-oak forest, where the highest values of the Shannon index indicate the multiplicity and diversity of mycobiota. The group of most widespread xylotrophs, promising for the most relevant at present environmental monitoring studies was selected. PCA method has showed the direct dependence between the findings of xylotrophic fungi and the stand state index of woody plants, which is predictable for artificial phytocoenoses in urban conditions. In the objects of the nature reserve fund of Ukraine164 species from 86 genera, 31 families and 10 orders (79,6 % of aphyllophoroid fungi of Kyiv Plato) were recorded. As result of our studies, 16 % of species to the list of xylotrophs of Kaniv Nature Reserve were added. Information on the species diversity of the investigated group of fungi of the Holosiiv National Nature Park were tripled; 62 species are listed for the first time for this object. 65 species were found in the forests of the Trakhtemyriv Regional Landscape Park. All of them are new for the park, as same as 28 species for the Oleksandriia State Dendrological Park of the National Academy of Sciences of Ukraine, where the group of aphyllophoroid fungi were hitherto not studied. In each of the investigated objects, species of xylotrophic fungi which do not occur in the rest territory of Kyiv Plato were recorded 37 such species in the Kaniv Nature Reserve, 9 species in the Holosiiv National Nature Park and 7 species in the Trakhtemyriv Regional Landscape Park. Some species of aphyllophoroid fungi of Kyiv Plato are rare, five species are listed in the Red Book of Ukraine (2009). Of the latter Clavariadelphus pistillaris, Hericium coralloides and Polyporus umbellatus are protected in the Kaniv Nature Reserve.
