Areoles contiguous, mostly flat, 0.2-0.8(-1.1) mm wide, 0.15-0.5 mm thick, separated by deep cracks. Apothecia 0.2-1 mm across, orange to orange red, with a concolorous or slightly paler margin. Epithecium orange, K+ red; hymenium and hypothecium colourless. hyaline, very variable, Ascospores 2-celled, polarilocular, hyaline, ellipsoid to broadly ellipsoid, 9.5-16.5 x 5.5-10.5 µm, the equatorial thickening (“septum”) 2-5.5 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
