06578782FF90B5311FBDFA1DFBEBFAD5.taxon	description	Specimen: Russia, Sakhalin Province, northern part of Iturup Island, Tsirk Bay, Tsirk River lower course, 45 ° 21 ’ 26 ” N, 148 ° 37 ’ 11 ” E, 20 m a. s. l., sedge-peat moss wetland in the flood plain, wet stone near stream, 12. IX. 2015, V. A. Bakalin & E. A. Borovichev K- 72 - 25 - 15, det. V V. A. Bakalin as Scapania uliginosa (Lindenb.) Dumort. and distributed in Hepaticae Rossicae Exsiccatae Fasc. IX. No. 300. Revised by Potemkin, Vilnet and Bakalin as Scapania gigantea. (LE, VBGI, KPABG). GenBank accession numbers are OM 501133 for ITS 1 - 2 nrDNA and OM 515128 for trn L-F cpDNA. The ITS 1 - 2 nrDNA and trn L-F cpDNA nucleotide sequences for specimen from Iturup Island were obtained according with protocols described in Potemkin et al. (2021). The test of genetic distances in MEGA 11 (Tamura et al., 2021) suggested ITS 1 - 2 nucleotide sequence divergence of the Iturup specimen from accessions of Scapania gigantea from Kunashir Island (MZ 272035) in 0.9 % and form Shikotan (MZ 272036) – in 0.8 %. The trn L-F sequence variability consists 0.4 % with accession from Honshu (MZ 274288), 0.2 % with accession from Shikotan (MZ 274290) and absent with accession from Kunashir (MZ 274289). The new record increases infraspecific sequence variation in Scapania gigantea compared with previously published 0.6 % in ITS 1 - 2 and 0.1 % in trn L-F (Potemkin et al., 2021), but agrees with level of infraspecific variation in the genus Scapania (Bakalin et al., 2019).	en	Kuznetsova, O.

This record of Scapania gigantea is the first for Iturup Island. Taxonomic notes. Despite Scapania gigantea was not accepted in the World checklist of hornworts and liverworts (Söderström et al., 2016), and in the Checklist of Japanese liverworts and hornworts (Katagiri & Furuki, 2018) after its resurrection by Potemkin (2001), it’s species status was confirmed by Potemkin et al. (2021).	en	Kuznetsova, O. I., Bakalin, V. A., Konstantinova, N. A., Laphina, E. D., Ganasevich, G. N., Potemkin, A. D., Vilnet, A. A. (2022): Bryophyte Molecular Barcoding Records. 6.

06578782FF90B5311FBDFA1DFBEBFAD5.taxon	description	Scapania gigantea from Itutup Island is distinct in the large plants, 4 – 6 cm long, deep purplish-black color, and characteristic development of teeth at and near the decurrent strip of the dorsal lobe. 2. Rudolgaea borealis (Frisvoll & Moen) Potemkin & Vilnet [Gymnocolea borealis (Frisvoll et Moen) R. M. Schust.] Contributors: N. A. Konstantinova, E. D. Lapshina, A. A. Vilnet, G. N. Ganasevich Specimen: Russia, Krasnoyarsk Territory, the southern part of the Taimyr Peninsula, southern tundra subzone in the middle reaches of the Dudypta River between the mouths of the Bataika and Avam rivers, sedge-hypnum floating fen on the shore of thermokarst lake with Carex chordorriza, C. rotundata, 38 m above sea level, 71.23266 ° N, 92.66041 ° E, single shoots in mats dominated by Scorpidium revolvens (Sw. ex anon.) Rubers with admixture of Oncophorus demetrii (Renauld et Cardot) Hedenas, Cinclidium subrotundum Lindb., Warnstorfia sarmentosa (Wahlenb.) Hedenäs. Coll. G. N. Ganasevich. YSU # 4354. The plants in the specimen are large (to 2 mm wide) and warm dark brown in color, which is somewhat different from the description of the species as green to yellow and golden brown. GenBank accession numbers are ON 175945 for ITS 1 - 2 nrDNA, ON 185621 for trn L-F cpDNA. The nucleotide sequences comparison between specimens from Gydansky (MZ 343174, MZ 353627) and Taimyr Peninsulas resolved in identity of reference loci. The species was described as Lophozia subg. Leiocolea (Frisvoll & Moen, 1980), but then transferred to Gymnocolea (Schuster, 1986) and, finally, as a result of molecular phylogenetic estimation, isolated into a distinct genus Rudolgaea (Potemkin & Vilnet, 2021). Until recently, the species was recorded for Fennoscandia, where it is not uncommon as well as for Greenland (Damsholt, 2002). For Russia, R. borealis was first recorded just last year for Gydansky Peninsula (Potemkin et al., 2021). Given the narrow ecological amplitude of the species and the occurrence of usually as individual shoots in the mats of mosses it can be assumed that the species overlooked during collecting and identification and has in fact circumpolar distribution, similar to distribution of rich fen mosses communities. 3. Solenostoma rossicum Bakalin & Vilnet Contributors: N. A. Konstantinova, E. D. Lapshina, A. A. Vilnet Specimen: Russia, Yamal-Nenets Autonomous Area, Nadymsky District, 40 km north of Pangody town, on the border of forest tundra and southern tundra subzones; Larix sibirica - Salix - Polytrichum - lichen tundra, on patches of bare clay soil, with admixture of Blasia pusilla, Cephalozia bicuspidata, Nardia sp., Schistochilopsis incisa, Scapania obcordata, Solenostoma cf. pusillum, 66.06586 ° N, 74.04234 ° E. Coll. E. D. Lapshina, 5 VIII. 2019 # 378 E / 3 - 1 - 19, KPABG 124440. GenBank accession numbers are ON 185619 for trn L- F cpDNA, ON 185620 for trn G-intron cpDNA. The nucleotide sequence divergence of newly sequenced samples (0 - 0.5 % in trn L-F, 0 % in trn G-intron as calculated in Mega 11 (Tamura et al., 2021 )) fits well in level of infraspecific variability (Kusnetsova et al., 2020).	en	Kuznetsova, O.
