This is a crustose, mosaic-forming lichen of hard, siliceous rock outcrops and boulders with a predominantly grey, silvery thallus and numerous, flat or irregularly shaped, brown-black discs that are not ringed by a margin. It grows on exposed, upland, quartzose rocks often alongside F. cyathoides and Rhizocarpon geographicum. North-west and south-east Ireland.

Key characteristics

  • The grey colour, irregularity of the disc shape and specialised habitat should distinguish it
  • The species forms dense and elaborate mosaics in mountain country.
