Description: Thallus crustose, mostly endosubstratic and inapparent, sometimes with scattered algae at the base of apothecia, 200-300(-400) μm thick, containing substrate crystals, the hyphae vertically oriented to intricate, c. 2 μm thick, the outer surface brown and corticate below the apothecial margins. Apothecia usually dispersed, rarely clustered in small groups, broadly attached, 0.2-1 mm across, 0.3-0.5(-0.6) μm high, emerging from a medullary base, the disc pale or dull brown, reddish-brown or yellow-orange when dry, reddish brown to red or orange when wet, lower than or even with margin, rarely convex, usually epruinose unless the margin is heavily pruinose; proper margin brown, pruinose or epruinose. Proper exciple expanding around the disc, 50-100 μm wide, IKI- but sometimes the IKI+ blue hymenial gel bleeding into it; epithecium brownish, <10 μm high; hymenium colourless, 70-100 μm high, the hymenial gel IKI+ dark blue, euamyloid; paraphyses 1-2 μm thick, the apical cells unexpanded, sometimes with a c. 3 μm wide gel cap with black pigment; subhymenium 20-30(-50) μm high, IKI+ dark blue, euamyloid; hypothecium colourless, 20-30 μm high, continuous with the proper exciple, subtended by a thin to continuous algal layer not extending into margins. Asci multispored, clavate, the apical dome K/I-, 60-80 x 15-17 μm. Ascospores 1-celled, hyaline, ellipsoid, 4-5 x 1-2 μm. Photobiont chlorococcoid. Spot tests: thallus K-, P-, KC-, P-. Chemistry: without lichen substances.
