Synonyms: Lecanactis werneri (Faurel; Ozenda & Schotter) Egea & Torrente

Distribution: C - Sar (Egea & Torrente 1994).

Description: Thallus crustose, episubstratic, thick, rimose or rimose-areolate, smooth to granulose, white to pale grey, usually delimited by a dark prothallus. Apothecia round, black, irregular in outline or ellipsoid, 0.4-1.2 x 0.3-0.5 mm, usually not abundant, at first immersed in the thallus, then slightly raised, with a pruinose, flat to slightly convex disc, and a thin, black, soon excluded proper margin. Proper exciple black, carbonized, extending below the hymenium; epithecium brown, 20-30 μm high; hymenium colourless, 85-125 μm high, I+ reddish; paraphysoids 2-2.5 μm thick; subhymenium brown, 25-35 μm high; hypothecium black. Asci 8-spored, narrowly clavate to cylindrical, fissitunicate, the apex with a narrow, K/I± pale blue apical dome penetrated by a small ocular chamber surrounded by a small, K/I+ dark blue, ring-like zone (Grumulosa-type of Egea & Torrente 1994). Ascospores 8-12-septate, hyaline but sometimes turning brown when overmature, spindle-shaped, 30-45 x 4-6 μm, with a 1.5-2 μm thick, gelatinous perispore. Pycnidia black, immersed. Conidia curved, 11-17 x 0.8-1 μm. Photobiont trentepohlioid. Spot tests: K- C+ red, KC+ red, P-. Chemistry: thallus with lecanoric acid.

Note: a southern Mediterranean species, hitherto known from North Africa and southwestern Europe, found beneath overhangs of siliceous rocks protected against salt-spray, usually along the coasts.
