Cornicularia normoerica (Gunn.) Du Rietz


Thallus fruticose, branches narrow, somewhat flattened, rather rigid, erect or radiating outwards, ascending and multiply branched at the tips, dark brown, glossy, lacking pseudocyphellae; apothecia apical, concolorous with the thallus, with flat, glossy discs, said to be more frequently produced at higher altitudes. On exposed, usually upland, hard, siliceous rocks in the north and west.

This lichen could be confused with Cetraria muricata but its branches are more uniformly directed and it lacks pseudocyphellae.
