Recorded only from west Cork, this rare ‘Dog lichen’ has a brownish felted underside to the thallus which lacks veins. The rather slippery-looking upper surface is blue-green, appearing browner when dry. Towards the edge (often curled upwards), there is a rough, hair-like tomentum (fur). This combination of characters is unique to the species. On sandy stabilising dunes.

Key characteristics

  • ‘Dog-lichen’, upper side blue-green appearing slippery, but drying rough with an erect furry layer, especially near the edges
  • Lower surface felty with no distinct pattern of veining.
