Description: Thallus fruticose, attached by a basal holdfast, consisting of strap-shaped, flattened, dichotomously branched lobes forming dense, up to 15 cm wide and tall tufts. Lobes 2-6 mm wide in lower part, narrower in apical parts, finely tomentose, brownish, with a more or less canaliculate, often reticulately ridged lower surface. Cortex strongly conglutinated after treatment with K, 3-7 µm thick, of thick-walled cells. Apothecia common and usually abundant, lecanorine, slightly stipitate, with an orange, 2-7(-10) mm wide disc and a grey or brownish, thick thalline margin covered in short, fine white hairs. Epithecium orange-brown, K+ red; hymenium and hypothecium colourless. 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, 10-15 x 5-7 µm, the equatorial thickening (“septum”) (1.5-)2-3(-4) µm. Pycnidia common, orange, c. 0.1-0.2 mm diam. Conidia bacilliform to narrowly ellipsoid, 3-4 x 1.5-1.7 µm. Photobiont: chlorococcoid. Spot test: thallus K-, C-, KC-, P- ; disc of apothecia K+ red. Chemistry: apothecia with parietin (major), fallacinal, teloschistin, and parietinic acid (all minor), and emodin (minor).
Note: on twigs of shrubs and small trees subject to spells of dry situations and frequent humid maritime winds; presently restricted to a few natural sites of Tyrrhenian Italy, on almost undisturbed sand dunes. It is included in the Italian red list of epiphytic lichens as “Endangered” (Nascimbene & al. 2013c).
