Description: Thallus squamulose, brown. Squamules 2-4 mm broad, rounded to lobulate, flattened to slightly convex, smooth, scattered to contiguous on a dark hypothallus. Lower surface pale at first, but often blackening with age, attached by a mat of dark rhizohyphae and by 0.5-1.5 mm long, mostly simple, sparse, dark rhizines. Upper cortex paraplectenchymatous, lower cortex absent. Perithecia frequent, laminal, pyriform, half immersed, to 0.5 mm broad, without involucrellum, with a 30-50 μm thick, carbonaceous, entire exciple. Paraphyses absent, substituted by periphyses. Asci 8-spored, narrowly clavate, the wall I . Ascospores 1-celled, hyaline, thin-walled, very variable in shape and size, from ellipsoid to club-shaped, (13-)15-20(-23) x (6-)7-9 μm. Pycnidia laminal, immersed, to 200 μm in diam. Conidia cylindrical, (5-)6-8(-9) x 1.5 μm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P- UV-. Chemistry: without lichen substances. Note: a mainly Mediterranean lichen growing in dry grasslands on calcareous substrata.
