Distribution: S - Si (Nimis & al. 1994).

Description: Thallus episubstratic, yellow-orange, forming up to 1 cm wide patches (but several thalli often confluent, covering larger surfaces), at first crustose-subsquamulose, with convex, sometimes lobulate squamules/areoles surrounded by a white to ochraceous prothallus, then minutely subfruticose, with globose to coralloid, 20-50 μm thick, often proliferating, isidia-like outgrowths. Apothecia biatorine/zeorine, yellow-orange, usually sparse, sessile or immersed amongst the granules, at first rounded, then irregular in shape, with a flat to slightly convex, rough disc, and an initially smooth and raised, finally excluded margin. Proper exciple fan-shaped, irregularly corticate, the medulla containing algae at the base; epithecium orange-brown, K+ purple-red; hymenium colourless, 60-80 μm high; paraphyses 1.5-2 μm thick at mid-level, the apical cells 2-3(-5) μm wide; hypothecium colourless, of conglutinated hyphae. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 11-14 x 4-7 μm, the equatorial thickening (“septum”) 3-4.5 μm. Pycnidia immersed, the ostiolar region poorly pigmented. Conidia ovoid, 2-3 x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-. Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).

Note: on calcareous rocks near the coast; hitherto known only from the type locality (Lampedusa). A very characteristic and easily recognizable species, to be looked for throughout the Mediterranean Region. According to Vondrák (in litt.) it belongs to Haloplaca.
