This powder lichen is a characteristic feature of shady crevices in old walls, stone bridges and ruined buildings that have had their mortar courses weathered over time. The apple-green colour and fluffy, cottony texture of the thallus is diagnostic. It is widespread in Ireland.

Key characteristics

  • The colour, texture and confinement to shaded calcareous habitats indicate this species
  • Most weathered mortar courses on the shaded side of old walls should support it. It is usually one of the first ticks in a lichen beginnerís notebook.
