• Caloplaca phlogina (Ach.) Flagey

There are no records for this species at present.

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
