At first sight, this species appears to be C. citrina on bark. What distinguishes it from other species is the pale, green-yellow soralia and thin thallus. It is never brightly coloured nor does it grow from ulcer-like swellings. It is rare on old parkland trees in Fermanagh, Donegal and Laois.

Key characteristics

  • Like C. citrina on bark but pale yellow-green coloured
  • Soralia punctiform on a thin thallus; elm, sycamore.
