Didymodon cordatus

This species was already recorded in Russia from the Caucasus and Russian Far East ( Ignatov et al., 2006). In the present study, four specimens from Russia (Dagestan Republic in the Caucasus, Altai Republic, and Primorsky Territory) were included; they were resolved within clade 5, in a maximally supported (PP 1, BS 100) subclade with four GenBank accessions of D. cordatus (specimens from Spain, North Ossetia/Alania, and China). Thus, species identity of Russian specimens and distribution of D. cordatus in the Caucasus, southern Siberia and south of the Russian Far East are confirmed.
