The coarsely granular, bright green and yellow crustose thallus of this lichen should be searched for wherever iron-rich rocks occur. Yellow soredia arise from the upper surface and not the edges of the areoles, often forming a continuous sorediate crust. Old, shaded copper and metal mine dumps may hold the best chance of finding this species. Discs are rare. Reactions negative. In Ireland, the species occurs mostly in the south and south-east.

Key characteristics

  • Thallus of coarsely granular areoles covered in bright green to yellow soredia
  • Among iron-rich spoil, metal-rich rock and on walls near former mine sites.
