Description: Thallus crustose, indistinct and endosubstratic or episubstratic and consisting of very small, scattered, orange-pink areoles often visible only around the apothecia). Apothecia biatorine, 0.2.1 mm across, at first immersed, then sessile and slightly projecting, with a flat to weakly convex, carmine red to orange-red, smooth disc, and an initially prominent, then thinner, slightly paler, smooth proper margin. Proper exciple 60-100 μm wide, with very few to no algal cells, prosoplectenchymatous; epithecium orange, K+ red; hymenium colourless, 50-70 mm high; paraphyses weakly branched in upper part, the terminal cells swollen, to 5(-7) μm wide; hypothecium colourless, prosoplectenchymatous, usually inspersed with oil droplets. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 8-12(-13.5) x (3-)5-7.5 μm, the equatorial thickening (“septum”) 2-5 μm. Pycnidia usually abundant, partially immersed, the ostiolar region orange-red. Conidia bacilliform, 2.5–3.5 x 1.5 μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with emodin, fallacinal, parietin, parietinic acid, and teloschistin.

Note: on steeply inclined, partially shaded surfaces of calcareous rocks above treeline; known from the mountains of southern Europe, and certainly ranging throughout the Alps.
