(= Coelocaulon muricatum (Ach.) Laundon)

Thallus fruticose, brown, glossy, densely branched, pseudocyphellae rounded, flat. Widespread on heaths and dunes. C. aculeata is more common and very similar, but less densely branched and with more strongly flattened main branches, these with elongated pseudocyphellae, usually in pits. Refs: Smith et al.
