Contributors: O.A. Belkina, A.A. Vilnet

Specimen: Russia, Murmansk Province, 68.275°N, 31.006°E, Tuadash-Tundry Mts., right source of Malaya Kon’ya river , altitude 500 m, tundra belt, S-facing gentle slope, dry bedrock outcrops among low-shrub-tundra; on soil over the rock ledge. 11 VII.1988; field number 207-2-88; KPABG ( M)#7094 Coll. and det. O. A. Belkina [ О. А.Белкина]

GenBank accession numbers are OP762027 for ITS1- 2 nrDNA and OP773813 for trn L-F cpDNA .

The nucleotide sequence data for the specimen from Tuadash-Tundry Mts. were obtained according with protocols described in Belkina & Vilnet (2019). This specimen did not reveal genetic variability with previously tested samples from Murmansk Province, Sweden and Norway in both ITS1-2 and trn L-F, and possess with them similar insertion of GCC-motif at the 5’-end of ITS2, which is absent in samples from Kamchatka and Chukotka (Mega 11: Tamura et al., 2021).

Trematodon laetevirens was recently found in Russia (Belkina & Vilnet, 2020) and now it is known in Khibiny Mts. ( Murmansk Region), Anadyr’ River Basin ( Chukotka Autonomous Region) and from Ushkovsky volcano ( Kamchatka Peninsula). This species is rare in the world and it was collected only in several locations: in Norway, Sweden ( Hallingbäck, 2006), Greenland ( Mogensen, 1980, 1983; Humle, 1987; Zander, 2007), Yukon Territory in Canada ( Vitt et al., 1987) and adjacent Alaska in the United States ( Stehn & Kofranek, 2014). New finding in Tuadash-tundra is the fourth known locality in Russia and the second in European Russia.
