This is a common, crustose species of peaty slopes, the walls of banks alongside moorland tracks and rotting plant material. It has a granular, C + red, pale grey to greenish thallus blazed with orange patches that quickly bring it to one’s attention. It is rarely with discs, and occurs in suitable habitats throughout Ireland.

Key characteristics

  • The C+ red reaction helps to suggest the species. It is separated from the equally frequent Trapeliopsis granulosa by the presence of bright orange spots on the surface of the thallus and the regular absence of discs
  • The orange blazed thallus makes it one of the few lichens beginners will be able to identify at a distance.
