in Frisch & al., Taxon, 63: 740, 2014. Basionym: Patellaria pruinata Pers. - Ann. Bot. (Usteri), 1: 28, 1794.

Synonyms: Arthonia algarbica Samp.; Arthonia impolita (Hoffm.) Borrer; Arthonia pruinata (Pers.) A.L. Sm.; Arthonia pruinosa Ach.; Arthonia pruinosa var. spilomatica Linds.; Pachnolepia impolita (Ehrh.) A. Massal.

Description: Thallus crustose, episubstratic, whitish grey to pale brown, effuse, rimose-cracked, 0.1-0.5(-1) mm thick, without a distinct prothallus. Apothecia arthonioid, round to angular, sometimes lobed, immersed to slightly erumpent, sometimes finally sessile, 0.3-0.7(-1) mm across, 0.1-0.25 mm tall, with a pinkish brown to dark brown, but heavily grey- to white-pruinose disc (calcium oxalates), without a distinct proper margin. Proper exciple poorly developed, of peripheral hyphal structures with crystals of calcium oxalates between hyphae; epithecium reddish brown, c. 15 µm high, covered in a thick layer of crystals, K+ grey or pale green; hymenium colourless to pale reddish brown, (40-)45-60 µm high, I+ blue rapidly turning red, K/I+ blue; paraphysoids branched and anastomosing, c. 1.5 µm thick, the apical cells up to 2.5 µm wide, with brown walls; hypothecium colourless, (70-)90-150(-170) µm high, I+ pale blue. Asci 8-spored, broadly clavate, semi-fissitunicate, with a large apical dome and a distinct ocular chamber, the tholus K/I-, Arthonia-type, 40-55 x 17-25 µm. Ascospores (3-)4-5-septate, hyaline, narrowly obovate, slightly pointed at one end, the upper cell not enlarged, (11-)14-17(-24) x (4-)5-7(-8) µm, without a distinct epispore. Pycnidia rare, immersed, 0.1-0.2 mm across, pale to red brown, the wall colourless or pale red-brown in which case it reacts K+ pale green. Conidia thread-like, usually curved, 10-16 x 0.5-1 µm. Photobiont trentepohlioid. Spot tests: thallus and apothecial pruina K-, C+ red, P-, UV-. Chemistry: arthoniaic acid.
