Description: Thallus crustose, episubstratic, continuous to rimose-areolate, white to pale grey, slightly farinose, often forming mosaics, the individual thalli delimited by a thin grey-black prothallus. Upper cortex lacking but epinecral layer usually present; medulla white, cretaceous. Apothecia immersed, punctiform, oval or elongate, up to 0.1 mm across, usually numerous, scattered, clustered, or arranged in lines, not aggregated into stromata, with a flat, black, but often whitish-pruinose disc. Proper exciple up to 15 µm thick, brown in upper part, pale below; hymenium colourless, 100-150 µm thick, I+ blue, K/I+ pale blue; paraphysoids richly anastomosing, 2-2.5 µm thick; hypothecium colourless to pale brown. Asci 8-spored, cylindrical, Opegrapha-type. Ascospores 4-7-septate, constricted at septa, dark brown, oblong-ovoid to oblong-fusiform, 17-26 x 5-7 µm, with a thick gelatinous sheath. Photobiont trentepohlioid. Spot tests: thallus and medulla K- or K+ pale yellow, C-, KC- or KC+ pale yellow, P+ yellow-orange, UV-. Chemistry: psoromic acid (major) and 2'-O-demethylpsoromic acid (minor).
Note: a tropical to subtropical-temperate species of oceanic, coastal areas, with a subcosmopolitan distribution (see Sparrius 2004), found on very hard siliceous rocks subject to humid maritime winds, mostly under overhangs; extremely rare and worthy of protection in Italy.

This form is characteristic of rocky overhangs always in the shade and sheltered from rain and splashes of sea water. Thallus white with unclear areoles, grayish a little yellowish in places, with circular or oval apothecia can form chains and give the impression of a network. Very frequently associated with Ingaderia sorediata and in particular with Ingaderia sorediata forme bleue.
