Description: Thallus squamulose-umbilicate, homoiomerous, slightly gelatinous when wet, 0.3-0.45 mm thick, in section with a loosely reticulate network of thin hyphae enclosing groups of cyanobacterial cells. Squamules black, epruinose, dispersed to crowded, closely attached, 5-10(-12) mm wide, button-like, epruinose, not isidiate, attached by a central, compact bundle of rhizohyphae, with a distinctly lobulate margin, the lobules radiating, discrete, diverging and rounded at apex, more or less dichotomously branched, smooth, slightly convex. Apothecia pycnoascocarps, 2-10 or more per squamule, at first immersed and urceolate but soon expanded and clearly lecanorine, 0.3-0.9(-1.2) mm across, with a dark reddish brown, concave to flat disc, and a thick, usually smooth thalline margin. Proper exciple poorly developed; epithecium brownish orange, 5-15 µm high; hymenium colourless, 80-150 µm high, the hymenial gel I+ blue, paraphyses moniliform, 3-4.3 µm thick, the upper cell clearly swollen and to 7 µm wide; hypothecium yellowish, 70-130 µm high. Asci 8-spored, broadly clavate, thin-walled, with a distinct amyloid outer cap, but no apical dome, Peccania-type. Ascospores 1-celled, hyaline broadly ellipsoid to ellipsoid, 7-15 x 4-10(-12) µm, the wall 1-2 µm thick. Pycnidia immersed, globose, unilocular. Conidia hyaline, ellipsoid, 2-4 x 0.5-1.5 µm. Photobiont cyanobacterial, chroococcoid, of a few 8-13 µm wide cells often penetrated by haustoria and surrounded by a gelatinous sheath which is colourless in inner parts, yellowish brown near the thallus surface. Spot tests: all negative. Chemistry: without lichen substances.
