Abstract (eng)
In the course of this dipoma thesis a qualitative mapping of macromycetes was performed, from September to November 2015, in the Zaubertal, a region in the district Linz-Land, community Leonding in Upper Austria. Two different forest sample plots, one kilometer distant from each other, were chosen as investigaton area. Although the larger plot had some scattered conifers, the forests in question are both mixed forests; the biggest parts are occupied by broadleafed trees. The forays took place approximately every second week. All samples collected were determined or approved with the help of Prof. Mag. Dr. Irmgard Krisai-Greilhuber from the Department of Botany and Biodiversity research of the University of Vienna.
The aim of this thesis is to contribute to the mycofloristic mapping of fungi in Austria by recording the fungal fruiting in the Zaubertal, as well as to provide detailed descriptions and analysis of all the taxa found and of their macro- and microscopic features, ecology and distribution. Scientific knowledge about ecological funtions and chemical constituents of fungi were integrated in the descriptions of the taxa, where interesting. In addition, data from comparable surveys in the area of Upper Austria are compared concerning ecological, geografical and climatic parameters.
In the year 2015 between September and November, 74 taxa were found in the two investigation plots. In plot 1, 60 taxa were found, in plot 2 there were 25. On the whole 66% of the taxa overlapped between the two plots. The two orders with the highest numbers of taxa were the Agaricales with 27% and the Polyporales with 24% of all taxa. Besides that, more than three-quarters of all fungi found were saprotrophs, the others parasites, perthotrophes and mycorrhizal fungi. Compared to other fungal mapping studies in Upper Austria about 30% of the Zaubertal species were also found in three areas nearby (28% in Kürnberg/Schiltenberg, 36% in Schiltenberg/Ansfeldnerberg, and 23% in Laimbach. Regarding the area of the Viennese Central Graveyard, only four correspondant taxa were found. Alltogether 31 taxa were unique to the investigation plots of the Zaubertal. These findings let assume, that parameters concerning the soil, ecology and plant population in every area have a big impact on macromycete appearance. The fungal recording in the area of the Zaubertal provides a first insight in the biodiversity of fungi from the late summer to the winter 2015 in this area.
