Biodiverzita dřevních hub v Arboretu Křtiny (Školní lesní podnik Masarykův les Křtiny)
Kotyz, Lukáš
The bachelor thesis focuses on the biodiversity of wood fungi in Arboretum Křtiny. Monitoring of the area started in February 2021, last visit was in January 2022. During this time 15 field trips were done in total. Overall 118 wood fungi were found in the arboretum. Of these, 10 species are in the Red list of fungi of the Czech Republic. Most of the species were found in October of 2021 (97), the least in May and June of 2021 (39). From the total number of macromycetes found, 88 % were basidiomycetes and 12 % ascomycetes. Most of the fungi species grew on Fagus sylvatica (77) and a total of 32 species were found on Salix ssp. White wood decay was noted in more than 90 % fungi species. 93 species were saprotrophic, 21 saproparasitic and 4 parasitic. More than 60 % of fungal species were present in the middle phase of wood decomposition. Over 1/3 of mushrooms preferred the 3rd degree of wood thickness (11–30 cm) and the 3rd degree of bark preservation. The rarest fungi found is Vararia investiens. The most commonly found species were: Fomes fomentarius s. l., Phellinus igniarius, Trametes suaveolens, Hypoxylon fragiforme, Kretzschmaria deusta, Xylodon flaviporus, Bjerkandera adusta, Ceriporiopsis gilvescens, Jackrogersella cohaerens, Eutypa spinosa and Biscogniauxia nummularia.
