Lobes flabellate, flat to undulate, 0.5-1.5 cm wide, with darker, granular, cylindrical or clavate, simple or sparingly branched, often apically depressed isidia. Lower surface covered in a white, yellowish or pale brown tomentum of 100-300 µm long hairs with elongated cells. Upper and lower cortex paraplectenchymatous, composed of a single layer of angular cells. Apothecia not observed in Italian material. Photobiont cyanobacterial (Nostoc), in long chains. Spot tests: all negative. Chemistry: without lichen substances.
