The shrubby or erect, red-brown or dark grey-brown thallus of this lichen bears a close resemblance to C. islandica (described elsewhere). It differs in the strongly channelled, inrolled lobes with marginal, bristle-like projections, and the Pd- medulla. It usually occurs above 900m on lichen-rich heaths. Old records were made from Counties Down, Cork and Kerry.
