Description: Thallus squamulose, pale to dark brown, dull, non- or very slightly pruinose. Squamules 3-8 mm broad, 0.3-0.5 mm thick, rounded at first, then crenulate, flattened to weakly convex, smooth, with an undulate-crisped edge, scattered to contiguous, rarely overlapping. Lower surface pale brown, sometimes darkening, attached by several. simple to weakly dichotomously branched, robust, 100-300 μm thick, several mm long, pale to brown rhizines, and by colourless, 3-5 μm thick rhizohyphae. Upper and lower cortex paraplectenchymatous, the lower cortex poorly developed, the cells not arranged in vertical rows. Perithecia frequent, laminal, half immersed, globose to broadly pyriform, to 0.65 mm in diam., without involucrellum, the wall colourless to pale brown throughout. Hymenium I+ blue; paraphyses absent, substituted by periphyses. Asci 8-spored, clavate, thin-walled, I-, without a tholus. Ascospores 1-celled, hyaline, ellipsoid, thin-walled, biseriate from the beginning, 12-15(-17) x 5.5-7.5 μm. Pycnidia laminal, immersed, black, to 0.5 mm in diam. Conidia oblong-ellipsoid, 3-4(-5) x 1.3-2 μm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P- UV-. Chemistry: without lichen substances. Note: a mainly Mediterranean-Atlantic to mild-temperate terricolous species found on loess and calciferous ground, most frequent in dry grasslands at relatively low elevations.
