With a thallus about the size of a one-cent coin, the clues to the identification of this species in the absence of any isidia, the abundant red-black discs and the short radiating lobes with bulbous tips. Spores are short (13-22&

371;m) and broad (8-12&

371;m), three-septate to submuriform. It occurs on damp calcareous rocks and boulders. In the Burren, it can be found at the edges of turloughs.

Key Identification Features:

  • Thallus small, cushion-forming, radiating, packed with discs; the olive-black lobes swollen at the top
  • On damp limestone, and occasionally inundated limestone boulders.
