Description: Thallus fruticose, pale yellowish green to pale green, up to 3(-6) cm long, growing from a narrow basal holdfast. Laciniae flattened, simple or irregularly and sparingly branched, (2-)3-5(-15) mm wide, markedly broadening from base, the surface smooth to irregularly uneven, the apices marginally lacerate, showing the soredia which develop inside the perforations, in the hollow medulla; soredia farinose. Cortex thin, the subcortex with radially arranged chondroid strands, best developed in basal parts; medulla lax and cottony in lower part of laciniae, hollow in upper part. Apothecia very rare, lecanorine, concolorous with thallus, with a concave disc and a distinct thalline margin. Epithecium poorly differentiated, pale green; hymenium and hypothecium colourless; paraphyses thick-walled, richly branched in upper part. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass) never penetrating through the entire d-layer, the wall K/I-, but the thin outer gel K/I+ blue, Bacidia-type. Ascospores 1-septate, hyaline, slightly to strongly curved, (14-)16-19(-21) x (4-)5-6(-7) µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC- (medulla) or KC+ pale yellow (cortex), P-; medulla UV+ white. Chemistry: cortex with usnic acid; medulla with divaricatic acid.
Note: a Mediterranean-Atlantic species found on the branches of littoral shrubs and small trees in maquis vegetation subject to humid maritime winds; mostly Tyrrhenian in Italy.
