Gyalolechia is a genus of lichen-forming fungi belonging to the family Teloschistaceae.[1] It contains about 20 species of crustose lichens.
The genus was circumscribed by Abramo Bartolommeo Massalongo in 1852. He included two species: G. bracteata and G. aurea.[2] Although Massalongo did not designate a type species for the genus, Josef Poelt assigned G. aurea to that status in 1965.[3] After Massalongo introduced the monotypic genus Fulgensia in 1853, Gyalolechia fell out of use.[4]
Gyalolechia was resurrected for use by Ulf Arup and colleagues in 2013, as part of a molecular phylogenetics-based restructuring of the Teloschistaceae. Gyalolechia, which is sister to the genus Blastenia, contains most of the species formerly assigned to the genus Fulgensia, the species group centred around the taxon formerly known as Caloplaca flavorubescens, and other species that contain fragilin as the dominant lichen product. Twenty-five species were included in the new circumscription of the genus,[4] but this number has since diminished as several species have been transferred from it to other new genera, including Athallia, Cerothallia, Elenkiniana, Laundonia, Mikhtomia, Opeltia, and Oxneriopsis.[5][6]
