Description: Thallus crustose, episubstratic, slightly gelatinous when wet, dark reddish brown to brownish black, granulose, the granules aggregated into irregular, 0.15-0.75 mm wide, smooth to verruculose, flat to slightly convex areoles separated by thin fissures, the central ones often subcoralloid, the peripheral ones sometimes slightly elongated and radiating. Thallus anatomy homoiomerous and paraplectenchymatous throughout, with a network of 2-3 µm thick hyphae enclosing the photobiont cells. Apothecia pycnoascocarps (with ascogones formed beneath pycnidia), immersed, 0.2-0.45 µm across, at first almost perithecioid with a pore-like disc, then with a slightly expanded, black, concave disc and a thin, granulose thalline margin. Proper exciple cupuliform, prosoplectenchymatous, 7-10 µm wide; epithecium yellowish brown to orange-brown, 5-12 µm high; hymenium colourless, 90-120 µm high, I+ blue turning red-brown, K/I+ blue; paraphyses simple or sparingly branched and anastomosing in upper part, more or less constricted at septa, 2-3 µm thick, the apical cells capitate; subhymenium colourless, 30-60 µm high, thicker in central part. Asci 8-spored, subcylindrical to subclavate, prototunicate, thin-walled, with a distinct amyloid outer cap but no apical dome, Peccania-type. Ascospores 1-celled, hyaline, broadly ellipsoid to subglobose, 9-13(-15) x 7-9 µm. Pycnidia immersed, globose, with simple conidiophores. Conidia ellipsoid, c. 3 x 1 µm, produced terminally. Photobiont cyanobacterial, chroococcoid, the cells single, measuring 7-11 x 4-7 µm, surrounded by reddish-violet (at the periphery) to colourless (in inner parts) gelatinous sheaths. Spot tests: all negative. Chemistry: without lichen substances.
Note: on basic siliceous rocks, especially basalt, in sunny seepage tracks.
Growth form: Crustose
Substrata: rocks
Photobiont: cyanobacteria, coccaceous (e.g. Gloeocapsa)

On otherwise dry surfaces with short periods of water seepage after rain
