The intertidal yeast communities inhabiting various environments in the territories of the White Sea Biological Station “Kartesh” (WSBS ZIN RAS) and the N.A. Pertsov White Sea Biological Station (WSBS MSU) were studied. A total of 31 yeast species were isolated using a conventional plating technique and identified using molecular methods. The yeast community of the White Sea intertidal zone consists of members that are typical for marine substrates, ubiquist species that are common in water and in low-temperature terrestrial environments, and a group of species that was isolated from marine substrates for the first time. The most diverse yeast communities formed on the surface of marine algae and in silt. Metschnikowia zobellii, which is a typical inhabitant of northern seas, was the most abundant yeast on algae from both biological stations. A new basidiomycetous yeast species, which was described in this work as Glaciozyma litorale sp. nov., dominated in the silt samples. The type strain of this new species is K94bᵀ (=KBP 4246ᵀ = VKPM Y-3850ᵀ = PYCC 6252ᵀ = CBS 12957ᵀ = DSM 28204ᵀ); MycoBank registration number is MB 805475.
