This orange-fruited, lichen epiphyte occurs mainly on the twigs and branches of basic-barked trees and shrubs. The relatively large (to 2mm diam.), yellow-orange discs bordered by a thick, grey, wavy margin is diagnostic. It is scattered throughout Ireland.

Key characteristics

  • The faint grey, crustose thallus, and rather large fruits with a thick, grey margin serve to separate it from other Caloplaca species growing on bark
  • Trees such as ash and sycamore are especially favoured.
