in Schmitt & al., MycoKeys, 4: 29, 2012. Basionym: Variolaria hemisphaerica Flörke - Deutsche Lich., 2, 2: 6, 1815.
Synonyms: Lecanora parella f. variolosa (Flot.) Anzi; Ochrolechia pallescens f. variolosa (Flot.) Jatta; Pertusaria hemisphaerica (Flörke) Erichsen; Pertusaria hibernica Erichsen; Pertusaria speciosa Høeg
Description: Thallus crustose, rather thick, white-grey to pale grey, often with a bluish tinge, smooth to cracked or slightly warted, sometimes wrinkled, forming large patches delimited by a white, rarely brownish, often zoned prothallus. Soralia rounded, 0.8-1.5(-2) mm across, usually discrete and strongly convex, sometimes coalescing when old, especially in central parts of thallus, not constricted at base, white to pale green-grey, the soralia granular, 40-100 μm in diam. Cortex thin, cartilaginous, paraplectenchymatous, of thick-walled, agglutinated hyphae; medulla white, of periclinally arranged hyphae. Apothecia unknown. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P; soralia K-, C+ carmine red; KC+ red, P-, UV+ bluish white. Chemistry: lecanoric acid (major), plus additional unknown substances.
