In the course of revision of the genus Stereodon
for Moss Flora of Russia, five East Asian species are recognized; most of them
are little known in Russia, and therefore are commented on in the present
paper. Stereodon dieckei is reported for Russia for the first
time. Confirmed collections of S. densirameus (Ando) Afonina
& Ignatova, comb. nov. are reported as all the previous records of this
species were based on wrongly identified specimens. Descriptions, illustrations
and comparisons with similar species, and distribution maps in Russia, are
provided. In addition a key for identification of Stereodon and
superficially similar taxa in Russia is given.
