This is a greenish-brown species of wet heathy places and the fully illuminated edges of blanket bog. It forms tablespoon-sized portions of scaly squamules on peat which are orange-brown to green-brown in colour. A dab of fresh bleach (C) will instantly turn the squamules bright green. Stalks (podetia) are rare. It is present in suitable habitats in Ireland, especially in the west.

Key characteristics

  • It is immediately separated from all other Cladonia species by the C+ bright green reaction. It is also UV+ white
  • Cladonia foliacea which is also rather ‘leafy’ occurs in drier, more basic habitats.
