The lichen genus Sarcogyne (Acarosporaceae) in Belarus

Abstract

The lichen genus Sarcogyne in Belarus is revised. Three species are accepted as occurring in the country, namely Sarcogyne belarusensis, S. hypophaea, and S. pruinosa. Of these, Sarcogyne belarusensis is the most widely distributed and commonest species. Sarcogyne pruinosa and S. hypophaea are rare taxa known from two and one localities, respectively. Morphological characters of these species are provided in comparison with similar taxa.
