Vytenis Žvinys Fungal species diversity and distribution in Puvočiai village surroundings in Varėna district Summary The aim of this bachelor’s thesis was to determine the diversity and distribution of fungal species in Puvočiai village surroundings in Varėna district. The work consists of five chapters. First chapter submits overview of mycological research linked to Puvočiai village. The second chapter provides an overview of the surroundings of Puvočiai nature environment. The third chapter presents the methodology of the research. The fourth chapter presents the results of investigation – the checklist of recorded fungi and the data on taxonomy and ecology of fungal species recorded in the surroundings of Puvočiai. In total 410 fungal species, from 233 genera, 35 orders and 3 divisions (Ascomycota, 152 species; Basidiomycota, 257 species, and Zygomycota, 1 species) were recorded. Nine species are protected in Lithuania and included in Red Data Book of Lithuania, namely Lepiota cortinarius (1 (E) category), Ganoderma lucidum (3(R)), Russula aurea (3 (R)), Trametes gibbosa (3 (R)), Geastrum quadrifidum (4 (I)), Lactarius scrobiculatus (4 (I)), Marasmius alliaceus (4(I)), Pycnoporus cinnabarinus (4 (I)), Xylaria polymorpha (4(I)). Majority of identified species are mycorrhizal fungi (232 species, ~57 %), and saprotrophic fungi (103 species., ~25 %). Other species are biotrophic fungi (45 species, ~11 %). Most of the species (272) were found in the forests, other were found in anthropogenic habitats and grasslands. In 2017 the research was carried out in four natural habitat types of European Union interest. Research revealed that the greatest variety of fungal species inhabited 91E0 Alluvial Forest (45 species, Shannon diversity index H'=2,99), and 9010 Western Taiga (33 species, H'=2.58). Fewer species diversity was present in 91T0 Central European lichen Scots pine forest (21 species, H'=2.4) and in 2330 Inland dunes with open Corynephorus and Agrostis grasslands (5 species, H'=1.26). Most similar fungal species compositions were in 9010 Western Taiga and 91T0 Central European lichen Scots pine forest habitats(Jaccard‘s index SJ =0.59). Species compositions of other habitats were much different from eatch other (Jaccard‘s index fluctuated between 0,03–0,07).
