Distribution: C - Sar.

Description: Thallus crustose, episubstratic, slightly gelatinous when wet, black when dry, dark red when wet, entirely granulose, the granules 0.1-0.2(-0.3) mm wide, usually more or less dispersed and not aggregated into areoles. Thallus anatomy homoiomerous and paraplectenchymatous throughout, with a network of hyphae enclosing the photobiont cells, Apothecia pycnoascocarps, immersed, 0.2-0.45 µm across, perithecioid, with a pore-like disc, and a thin, granulose thalline margin. Epithecium orange-brown; hymenium colourless, K/I+ blue; paraphyses simple or sparingly branched and anastomosing in upper part, more or less constricted at septa; subhymenium colourless. Asci 8-spored, subcylindrical, functionally unitunicate, the wall I+ blue. Ascospores 1-celled, hyaline, ellipsoid, 11-16 x 6-8 µm. Pycnidia immersed, pyriform. Conidia ellipsoid, very small. Photobiont cyanobacterial, chroococcoid, the cells single or clustered, surrounded by a reddish-violet gelatinous sheath. Spot tests: all negative. Chemistry: without lichen substances.

Note: a very poorly known and rarely collected species, found on basic siliceous rocks, in sun-exposed seepage tracks, mostly in the Mediterranean belt, near the coast.
