Description: With its granular, patch-forming habit, bright or golden yellow colour Chrysothrix candelaris is one of Ireland’s commonest and most conspicuous crevice-inhabiting lichens of rough-barked trees. It can sometimes form extensive, spreading patches especially on the dry boles of sheltered oaks. Discs are unknown from Irish material.

Key Identification Features:

  • Finely granular, golden yellow spreading crust (trees, rarely on rock)
  • A dry crevice lichen of rough bark.
