Abstract

At the eastern border of small-leaved linden (Tilia cordata Mill.) dispersal, in the subzone of small-leaved forests of Western Siberia, 5 main types of linden forests were identified: fern, horsetail, reedgrass, broad-grass, forb-herbs. The taxonomic list of linden vascular plants includes 74 species, from 64 genera and 31 families. Forb-herbs linden forest is characterized by the widest species diversity, while fern forest is characterized by the smallest. The floristic similarity between different types of linden forests ranges from 43.3 to 63.2 %. In the whole floristic complex of linden forests, 35 % is accounted for the nemoral group, which includes associated linden relicts of the tertiary flora of broad-leaved forests. In linden-containing forests, 77 species of xylotrophic fungi from 26 families and 7 orders were observed.
