Distribution: C - Sar (Cossu & al. 2015). S - Cal (CLU 17410), Si (Ottonello & Romano 1997, Ottonello & al. 2011, Cataldo & Ravera 2012b).
Description: Thallus fruticose, greenish to greenish grey, 1-2(-3) cm tall, erect to prostrate, rigid, abundantly branched, firmly attached by a basal holdfast, several thalli often forming dense carpets on the rock. Branches more or less flattened, 1-5 mm wide, longitudinally striate, the apical parts palmately and finely divided into small, short digitiform lobules developing small soralia on the lower side; soredia granulose, concolorous to thallus. Subcortex cartilaginous; medulla white, compact. Apothecia extremely rare, lecanorine, mostly terminal. Asci 8-spored, clavate, Bacidia-type. Ascospores 1-septate, hyaline, often poorly developed. Photobiont: chlorococcoid. Spot tests: cortex K-, C-, KC- or KC+ pale yellow, P-, UV-; medulla K- or (rarely) K+ yellow turning red. Chemistry: cortex with usnic acid; medulla and soralia without lichen substances, or rarely with norstictic acid.Note: on the top of exposed siliceous boulders frequently visited by birds in Mediterranean Italy.
