Distribution: N - TAA. C - Sar (TSB 13439).
Description: Thallus crustose, endosubstratic or more rarely very thinly episubstratic, continuous to rarely finely rimose, white to yellowish-ochre. Medulla white, I- (rarely I+ pale blue). Apothecia lecideine, adnate and constricted at base, black, epruinose and somehow shiny or finely bluish-pruinose, 0.2-1.3 mm across, with a slightly concave to flat, finally sometimes convex, non-umbonate disc, and a thick, prominent, usually persistent, often wavy proper margin. Proper exciple c. 40 µm wide, black, the hyphae 5-9 µm thick, K+ intensively purple; epithecium blue-green or greenish brown (the two colours often present in the same apothecium), 12-25 µm high, K-, often with a layer of crystals; hymenium colourless or greenish in upper part, 70-130 µm high; paraphyses coherent, branched and anastomosing, 1.7-2.2 µm thick at mid-level, the apical cells to 3 µm wide; hypothecium dark brown to brown-black (paler than exciple), the upper part sometimes greenish and K+ purple, c. as twice as high as the hymenium. Asci 8-spored, clavate, with a I+ pale blue tholus and a central amyloid tube, approaching the Porpidia-type. Ascospores usually poorly developed, 1-celled, hyaline, ellipsoid, 11-14 x 5.5-6.5 µm, with a gelatinous perispore. Pycnidia black, immersed, globose. Conidia bacilliform, 3.5-9 µm long. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on calciferous rocks, including calcareous schists, near and above treeline; to be looked for further in the Alps.
