This common crustose lichen has a shiny, chestnut brown thallus bearing abundant dark brown discs with a paler, somewhat crumpled margin. It is frequent on hard, acid rocks and boulders in the uplands and also along the coast.

Key characteristics

  • The thick, cracked, shiny dark brown thallus and discs with a pale margin should suggest this species
  • The white, UV reaction helps to confirm it as do the simple spores.
