Prylutskyi O. Agaricoid fungi of the Kharkiv Forest-Steppe.

The dissertation is aimed to reveal the diversity and ecological features of agaricoid fungi of Kharkiv Forest-steppe. 468 species of agarics belonging to 121 species, 32 families, and 4 orders of the Agaricomycetes class are documented on the territory of the Kharkiv Forest-Steppe. 122 species have been registered for the territory of the Kharkiv Forest-Steppe for the first time, 23 fungal taxa was new for Ukraine. We delineated the key habitats for the conservation of agarics of Kharkiv Forest-Steppe. It was showed that the mycoflora of the Kharkiv Forest-Steppe have the features of both forest and steppic ones. The species composition of the agaricoid fungi of ecotones on the edge between native and non-native habitats was shown to be more similar to the native habitat. Substrate preference and fruiting rate for Pleurotus calyptratus, was revealed. Using regression analysis it was confirmed that the fungal fruiting pattern is determined rather by the set of weather conditions preceding the observation date. Using multiple linear regression and non-metric multidimensional scaling.
