[in Russian with English abstract :]
The lichen biota of Belarus lists 406 corticolous species. Of these, 213 (35.7%) species
are obligate epiphytes. Crustose lichens make up the majority of obligate epiphytes (157
species, or 73.7%). Apparently, this can indicate the decisive role of the morphology and
chemistry of the substrate for the closely contacted lichen thallus. Facultative epiphytes are
represented by 193 species, which are quite widely represented by foliose and fruticose life
forms (51.3%). Facultative epiphytes inhabit rotting and processed wood, stony substrates, soil
(including forest litter), mosses, leaves (needles), root turnouts and metal objects. Wood is
inhabited by 154 facultative epiphyte species, of which 80 lichens are strongly epiphyticlignicolous.
The lichen diversity of tree bark and wood is relatively similar; the value of the
Sørensen-Dice index is equal to 0.51. Soil is the second most important substrate after wood
for facultative epiphytes. It is inhabited by 55 lichens, most of which are represented by
Cladonia and Peltigera species. 46 species of facultative epiphytes were found on mosses.
These are represented mainly by cyanobiont-containing lichens, broad-lobed species, as well as
many by the representatives of the genus Cladonia. The stony substrate is suitable for 43 facultative
epiphytes species and is characterized by a high specificity of lichen biota. Its Sørensen-
Dice index is equal to 0.13. Most of these representatives are common in urban environments.
Fungi, lichens, root inversions, leaves, and metal are predominantly inhabited by multisubstrate
lichen species.
Keywords: epiphyte, phorophyte, lichen biota, substrate, affinity index.
