Description: Thallus fruticose, consisting of yellowish green to greenish grey, rigid, erect, simple or sparingly branched from a basal holdfast, 1-6 cm long, 0.2-4(-6) cm wide, in part reticulately ridged laciniae with an irregular network of large cracks exposing the medullary layer, from which granular soredia (or schizidioid isidia) originate. Cortex 2-layered, the outer part paraplectenchymatous, the inner part cartilaginous; medulla compact. Apothecia extremely rare (not observed in Italian material). Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC- or KC+ pale yellow, P-; medulla and ‘soralia’ K- or K+ orange-red, C-, KC-, P- or P+ yellow to orange.
