List of 162 moss
species collected in the Ust-Nera
region (Oimyakon District) is presented.
It includes some interesting records of xeric
species growing on steep steppe
slopes on the banks of
Indigirka River and its tributary,
Nera River, i.e., Hilpertia velenovskyi and Pterygoneuron kozlovii.
In the mountain
tundra communities on Taas-Kystabyt Mt. Range (Chersky
mountain system) two rare species
were found. For Grimmia fuscolutea it is the fifth
locality in Russia; it was
previously known in the Caucasus,
Altai, Baikal Lake area and
Kamchatka. Finding of the suboceanic
species, Pseudotaxiphyllum
elegans, in the area with
severely continental climate is quite
unexpected; its identity is confirmed
by molecular markers.
