Quél. and S. semiglobata (Batsch : Fr.) Quél. S. semiglobata is common throughout the study area and S. alcis in Fennoscandia, S. dorsipora and S. luteonitens are rare or very rare and possibly decreasing in Fennoscandia, S. islandica is known from Iceland, and S. arctica from Iceland and arctic Russia. The distribution of each species in the study area is mapped, and their taxonomy, ecology and relationships are discussed.
