Look for this Caloplaca below overhanging, base-rich rocks such as basalt and schist for you will never see it on limestone. The orange to brown-orange thallus is reminiscent of C. cirrochroa in the small dotting of orange soralia, but the thallus is much broken up and often linked by strands of white prothallus. It is a species of mountains and exposed coasts. In Ireland, it has been recorded from County Antrim and from the Brandon Mountains in County Kerry.

Key characteristics

  • Non-ring forming, brown-orange scrappy thallus of dispersed areoles on a prothallus of white strands
  • Areoles (bits of thallus) dotted (or not) with orange soralia; underhangs of base-rich rock; exposed sites.
