The epiphytic mosses in
Buryatia occur mostly on bases of tree trunks, up to 10-20 cm above groun only.
Despite of the severe climate and very low winter temperatures, however, some
epiphytic mosses at places are reaching up to 8-10 m, mostly on trunks of deciduous
trees in proximity of hot springs. Orthotrichum speciosum grows on twigs
of Picea obovata up to 3 m above ground. The most widespread epiphytic
moss within studied area is Pylaisia polyantha.
