This compact, yellow-green crustose lichen with cracked-mirror-like thallus studded with green-black discs is a species of low siliceous outcrops and boulders in upland and mountain areas. In Ireland, it has a patchy distribution except for near the coast and around the mountains of the north and west.

Key characteristics

  • The yellow-green, cracked (areolate) thallus crammed with green-black discs and siliceous rock habitat distinguishes this species
  • Lecanora polytropa has paler green to green-brown (never blackish) apothecia and a thallus of scattered areoles.
