Distribution: C - Tosc, Sar. S - Si (Nimis & al. 1994).

Description: Thallus crustose, episubstratic, homogeneously bright orange, areolate in central parts, more or less distinctly lobulate in marginal parts, forming irregular rosettes which are often confluent and cover large areas, without a distinct prothallus. Apothecia numerous, sparse or more often clustered, rounded or irregular, 0.2-0.8 mm across, with a more or less flat, deep orange disc, and a thin, usually somehow paler orange margin. Epithecium orange-brown, K+ red; hymenium colourless; paraphyses 1-1.5 µm thick at mid-level, the apical cells weakly enlarged, 1-2(-2.5) μm wide; hypothecium colourless. Asci 8-spored, cylindrical-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, (9-)10-12 x 4-6 μm, the equatorial thickening (“septum”) 3-5 μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ 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: a Mediterranean lichen found on siliceous, more rarely calcareous rocks near the sea, often associated with specimens identified as F. marina (see note on that species), apparently without transitional specimens.
