This crustose epiphyte has a yellow-green thallus composed of minute isidia-like granules. Discs (to 1mm diam.) are common, orange-brown to almost red with pronounced margins. These are quick to attract the attention of the lichen hunter. It occurs on the basic bark of nutrient-rich trees, and is relatively frequent throughout Ireland.

Key characteristics

  • The habitat, granular, yellow-green thallus and reddish-brown fruits are diagnostic
  • It often occurs squeezed in between foliose species.
