Wherever peat cuttings have exposed vertical surfaces which have undergone colonisation by lichens, this species should be looked for. C. incrassata has a thallus usually dominated by small, yellowish, powdery scales (squamules). The small red discs sit almost flat against the squamules so appear hardly stalked like many others of the Cladonia tribe. Spot tests are usually K-. It also grows on rotting wood. Midlands and north-west Ireland.

Key characteristics

  • Small, yellowish, sorediate squamules bearing tiny, barely-stalked, red discs
  • Habitat of rotting wood and exposed peat cuttings.
