Description: Thallus squamulose to subcrustose, beige to pale brown, dull, epruinose, thin, closely adpressed to the substratum. Squamules 0.3-1.5(-2) mm broad, 0.1-0.2 mm thick, rounded to crenate, flattened to slightly convex, smooth, contiguous, developing on a pale hypothallus; lower surface pale, attached by c. 4 µm thick, pale rhizohyphae. Upper cortex paraplectenchymatous, 10-25 µm thick, of small isodiametrical cells, poorly differentiated from the algal layer, overlain by a 20-50 µm thick epinecral layer; medulla and lower cortex not differentiated. Perithecia developing from the hypothallus among the squamules, globose, projecting, with an apical involucrellum reaching up to the half of the perithecium, up to 0.35 mm across. Exciple dark throughout, of tangentially arranged, elongated cells; hamathecium of periphyses, interascal filaments absent. Asci 8-spored, clavate, with biseriately arranged spores, the wall I-. Ascospores 1-celled, hyaline, ellipsoid, thin-walled, 13-17(-18) x 6-7(-8) µm. Pycnidia unknown. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
