Description
''Solenopsora'' lichens produce thalli of various morphologies, including crust-like (crustose), scaley (squamulose), and leafy (foliose). Depending on the species, the apothecia may be immersed on the substrate, emergent on the substrate surface, or somewhat elevated on a stalk (''stipitate''). A combination of microscopic characteristics define the genus ''Solenopsora''. They all have
