Anal. Inst. Bot. Cavanilles, 35: 89, 1978.

Synonyms:

Distribution: C - Sar.

Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, monophyllous, sometimes deeply dissected and appearing polyphyllous, orbicular in outline, 3-5(-7) cm wide, rarely wider. Upper surface pale to dark grey, sometimes with a brown tinge, darker towards the margins, dull, even or slightly radially wrinkled and distinctly areolate around the umbilicus, scabrous and rimose at margin, which are often down-turned. Lower surface pale grey-white tinged pink, smooth to slightly areolate towards the margins, with numerous cylindrical, simple or branched, concolorous or dark rhizinomorphs, which usually lack around the umbilicus; thalloconidia absent. Upper cortex 20-25 µm thick; medulla thin, white; lower cortex thinner than in the typical subspecies. Apothecia unknown. Pycnidia numerous throughout the upper surface, immersed, bottle-shaped, with a dark brown wall and a black ostiole. Conidia bacilliform, c. 3-4 x 0.8-1 µm. Photobiont chlorococcoid. Spot tests: K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric acid, and small amounts of lecanoric and hiascic acids.

Note: a recently-described taxon, hitherto known from the Iberian Peninsula and from Sardinia; it could be more widespread in the Mediterranean mountains.
