Description: Thallus orange- to ochraceous yellow, of 0.2-0.6 mm subsquamulose areoles, or reduced to small granules-areoles around the apothecia, forming 2-4 mm wide spots on the thalli of the host. Upper cortex paraplectenchymatous; medulla white, loosely paraplectenchymatous, I+ blue (reaction best visible at the base of old apothecia). Apothecia zeorine, usually in small groups and mutually deformed, (0.2-)0.4-0.6(-0.8) mm across, with an orange-brown, flat to slightly convex, rough disc, and a thick, paler, smooth margin; a reduced thalline margin is sometimes visible in young apothecia. Epithecium brownish orange, K+ red; hymenium colourless, 80-90 μm high; paraphyses simple or sparingly branched, the apical cells up to 5 μm wide; hypothecium colourless, of strongly conglutinated hyphae. 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, broadly ellipsoid to ellipsoid, (9-)10-13(-15) x 6-8(-9) μm, the equatorial thickening (“septum”) (1-)2-4 μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).Note: on calcareous schists, parasitic on Aspicilia candida and A. polychroma; known from South Tyrol, but probably more widespread in the Alps.
