ABSTRACT. Moss flora of the area around the second highest peak of Yakutia, the Mus-Khaya Mt., is studied. This area is close to the coldest place of the Northern Hemi­sphere. Severe condition and high content of heavy metals result is a rather poor diversity of 180 species; their list is annotated by altitudinal range, frequency, locali­ty and habitat information. Map of Gollania turgens is provided; Mielichhoferia mielichhoferiana, M. elongata and Andreaea papillosa are discussed and illustrated.
