Comm. Soc. Critt. Ital., 1: 158, 1862 nom. nud.
Synonyms: Rhizocarpon phalerosporum (Vain.) Vain.
Description: Thallus crustose, episubstratic, areolate, forming up to 10 cm wide patches, consisting of 0.3-0.6(-1) mm wide, round, reddish brown to brown, flat to slightly convex, peltate areoles with free, often grey or blackened margins, usually more or less scattered on a conspicuous black hypothallus. Cortex overlain by a 20-30 μm thick epinecral layer; medulla white, I- (rarely I+ faintly blue). Apothecia lecideine, black, slightly constricted an base, scattered on the hypothallus, c. 0,6 mm across, at first with a flat disc and a thick proper margin, finally convex and immarginate. Proper exciple brown-black, almost carbonized in outer part, K+ purple-red (solution); epithecium dark grey-green to brown, K+ reddish or K-; hymenium colourless, 100-150 μm high; hypothecium brown-black. Asci 8-spored, clavate, fissitunicate, with a well-developed tholus that is K/I- in lower part and K/I+ blue near the apex, lacking an ocular chamber, Rhizocarpon-type. Ascospores muriform, at first almost colourless, finally brown, 28-38 x 14-21 μm, halonate at least when young. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-. Chemistry: medulla with friesiic acid.
