A distinctive crustose lichen with a thick, pale grey, warted thallus. Conspicuous large black apothecia with pale margins are abundant. This is a common species of the 'Grey Zone' but also is found on siliceous rocks inland. Superficially similar to Lecidella subincongrua, but that species has a pale ochre thallus and the convex apothecia have black margins.
