This very small species is found on sheltered vertical rock outcrops in upland areas. The discs are reminiscent of those of M. lutulata or M. sylvicola in their almost black colour and size but the thallus is paler, with no greenish pigmentation present in the squashed disc. In Ireland, the species is poorly known.
