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.
