The poorly known Rudolgaea fascinifera is firstly recorded for Krasnoyarsk Territory (Taimyr Peninsula) and confirmed for Republic of Sakha (Yakutia). Based on these findings the distribution of the species, its ecology, phytocenotic preferences and the range of morphological variability has been significantly clarified. It is shown that the two known species of the genus Rudolgaea (R. fascinifera and R. borealis) differ not only in morphology, but also coenotically. For the first time, data on the nucleotide sequences of three specimens from Russia were obtained and compared with the previously sequenced holotype of the Rudolgaea fascinifera from Alaska. The level of variability of nuclear ITS1-2 and plastid rbcL and trnL-F corresponds to intraspecific, despite the remoteness of localities.
