In 2013 the monotypic genus Ascidiota C.Massal. was found in the Republic of Buryatia and the Taymyr District of Krasnoyarsk Territory, Russia. These are the most northerly known localities for Ascidiota. An illustration, distribution map and complete description of A. blepharophylla C.Massal. are provided. Variation, differentiation, and distribution of A. blepharophylla are discussed. A key to distinguish Ascidiota from morphologically similar species of the genera Porella L. and Frullania Raddi is presented. Sequences of nrITS1-5.8S-ITS2 were identical in plants from Buryatia and Alaska. This supports the hypothesis of the integrity of this monotypic genus. Inadequate bryological exploration of many northern territories suggests that the list of Ascidiota records, especially in north Asia, will be extended in the future.
