Description: Thallus crustose, episubstratic, usually < 1 mm thick, rimose to usually areolate, chalky white to whitish grey or sometimes rust-red or ochre (due to incrustations of iron-oxides), often delimited by a black prothallus. Areoles relatively small (<1 mm across), angular, contiguous, flat to slightly convex. Cortex without an epinecral layer; medulla white, I+ intensely blue-violet. Apothecia lecideine, black, arising between the areoles, constricted at base, round or more frequently angular, 0.5-1.2(-2) mm across, with a flat to slightly convex, dull, usually epruinose disc, and a persistent proper margin. Proper exciple black-brown in outer part, colourless within, the unpigmented part 30-80(-120) µm wide; epithecium greenish black to brownish black, K+ bright blue-green; hymenium colourless, 45-80 µm high, I+ blue; paraphyses usually unbranched and rarely anastomosing, the apical cells, swollen, 3.5-5 µm wide; hypothecium almost colourless to pale brown. Asci 8-spored, narrowly clavate, thick-walled, with a K/I+ pale blue tholus and a strongly amyloid, thin apical cushion, surrounded by a I+ blue outer layer, Lecidea-type. Ascospores 1-celled, hyaline, broadly ellipsoid, 9-16 x 4.5-8 µm. Pycnidia black, immersed. Conidia bacilliform, more or less straight. Photobiont chlorococcoid. Spot tests: thallus K+ yellow turning red (needle-like crystals), C-, KC-, P+ yellow-orange. Chemistry: norstictic acid syndrome.
Note: doubtfully distinct from var. lapicida and perhaps just a chemical strain of the latter, with a similar distribution and ecology, this taxon is widespread and common in upland areas throughout the country, but most frequent in the Alps. The record from Venezia Giulia in Nimis (1993: 384) has been excluded, as it actually is from Slovenia.
