Description: Thallus crustose, episubstratic, parasitic on aspicilioid lichens, deep orange-red to scarlet red, somehow glossy, consisting of up to 0.6 mm wide, dispersed, convex areoles. Thallus cortex c. 15 µm thick, poorly delimited, paraplectenchymatous; medulla well-developed, I+ blue. Apothecia zeorine, scattered to crowded, round to angular, sessile and slightly constricted at base, 0.5-0.9 mm across, with a deep red-orange to carmine red, flat to slightly convex disc (slightly darker than the thallus) and an initially thick and prominent, usually smooth proper margin concolorous with thallus. Thalline exciple with algae almost to the edge; proper exciple slightly fan-shaped at the periphery; epithecium brownish red, with a coarse epipsamma reacting K+ red; hymenium colourless, 50-70 µm high; paraphyses moderately branched, c. 1 µm thick at base, the apical cells only slightly thickened, up to 1.5 µm wide; hypothecium colourless, inspersed with oil droplets. Asci 8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, (11-)13-15 x (5-)6-8 µm, the septum (3-)4-5.5 µm thick. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with unidentified anthraquinones.
Note: a species with minute thalli and one to several sessile apothecia, both bright red; parasitic on silicicolous Aspicilia-species at high elevations; widespread in the Alps, but rare. Never reported from Italy but known from neighbouring countries; to be looked for in the Alps.
