Description: Thallus crustose, endosubstratic or of scattered granules, white to yellowish white, poorly evident. Apothecia 0.3-0.4 mm across, usually sparse, rounded, with a reddish brown to dark brown, slightly convex disc, without an evident margin (with a few algal cells restricted to the lower edges of the apothecium). Thalline exciple absent or very poorly developed; proper exciple thin, poorly evident; epithecium yellowish brown to brown, the pigment rapidly extending to the upper part opf the hymenium; hymenium colourless or yellowish in upper part, 60-85 µm high; paraphyses few, hardly exceeding the number of asci, coherent, not or only slightly swollen at apex; hypothecium pale. Asci 8-spored, narrowly clavate, with a K/I+ blue tholus and a central non-amyloid area, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid, thin-walled, 11-16 x 4-7 µm, without a gelatinous perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
