Description: Thallus crustose, episubstratic, dark grey to grey-brown, sometimes almost black, rimose-areolate, often delimited by a fimbriate dark prothallus, smooth or blastidiate in some forms. Apothecia adnate to sessile and slightly constricted at base, 0.3-0.8 mm across, with a flat, epruinose, orange to olive-orange disc (tending to blacken in old apothecia) and a yellow-orange, persistent proper margin, which is sometimes surrounded by an incomplete thalline margin at the base. Proper exciple of radiating hyphae, orange-brown in outer part, colourless within; epithecium orange, K+ red or K+ violet, N + violet, C-; hymenium colourless, 50-70 µm high; paraphyses simple or sparingly branched, the apical cells slightly swollen; hypothecium colourless. Asci 8-spored, cylindrical-clavate, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, broadly ellipsoid, 10-17 x 5.5-10 µm, the equatorial thickening (“septum”) 4-7 µm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly violet, C-, KC-, P-, N+ violet; apothecia K+ red, C-. Chemistry: non-chlorinated anthraquinones in apothecia (C- in section), Sedifolia-grey pigment in thallus.

Note: a Mediterranean-Atlantic species in Europe, found on base-rich or eutrophicated siliceous rocks, especially on basalt, sometimes periodically submerged in Mediterranean creeks and rivulets, or on exposed surfaces of boulders near the soil surface.
