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.
