The bryophyte flora
of Eriechka River upper course includes 66 species of
liverworts and 262 species of mosses. Annotated list provides data on species
frequency, habitat characteristics and associated species. Species composition
in different habitats is overviewed. Distribution of some
rare species, as well as a taxonomic status of Herbertus
arcticus are discussed. Pseudoditrichum mirabile Steere
& Z. Iwats. is
found in Russia for the first time. This is the second worldwide record of this
unique species with ambiguous taxonomic position, described in the monotypic
family Pseudoditrichaceae. Differences in moss flora
between Proterozoic siliceous limestone and Cambrian
dolomites poor in silica are observed. Most Seligeria
species in the study area were found in ecotopes
formed by Proterozoic siliceous limestone.
