Fruticose lichen. Podetia grey-green, small, to c. 1cm, commonly arising from the centres of the basal squamules, forming neat, abruptly expanded cups on cylindrical stalks, densely sorediate, basal squamules large, spreading, rounded to shallowly lobed, densely farinose sorediate beneath; pycnidia and apothecia bright red, eventually borne on fingerlike projections from the rims of the cups, but young pycnidia brown and at this stage set in the in-turned cup margins, or pycnidia absent. Commonly only the basal squamules are present. On damp trunks and rotting wood, reportedly also on peat.
