About Squamulea subsoluta (Nyl.) Arup, Søchting & Frödén
Squamulea subsoluta (Nyl.) Arup, Søchting & Frödén is a squamulose, saxicolous (rock-dwelling) lichen that belongs to the family Teloschistaceae. Finnish lichenologist William Nylander first formally described this taxon in 1873, when he classified it as a variety of Lecanora murorum. Three years after this initial description, in 1876, Nylander raised the taxon to full species status as Lecanora subsoluta. In 2013, Ulf Arup and his colleagues transferred the species to the genus Squamulea, as part of a molecular phylogenetics-based restructuring of the family Teloschistaceae.
