Bacidina ferax – a new species for the lichen flora of the Middle European Russia

Bacidina ferax was described by Stefan Ekman in 2023, particularly basing on the collections from the North-East of the European Russia (Komi Republic). Herewith, B. ferax is reported for the first time for the Middle European Russia – from the Nizhny Novgorod Region. A complete morphological description, including the characters, distinguishing B. ferax from the related species, in Russian is given; its distribution range is characterized. The obtained results make a valuable contribution to the knowledge of the global distribution range of B. ferax. The specimens from Kerzhensky Nature Reserve are kept in the lichenological herbarium of the Komarov Botanical Institute (LE L, Saint- Petersburg), duplicate – in the herbarium of the Altai State University (ALTB, Barnaul).
