• Ochrolechia frigida (Sw.) Lynge

There are no records for this species at present.

Known only from west Donegal, O. frigida is rare in Ireland. It is a species of low vegetation on high moors and mountain tops. The white to pale grey thallus begins as a thin, granular crust which later develops curved spiny extensions which, from afar, can appear like thin strands of wax. Discs are rare, pale brown or red-brown with a thin rim.

Key characteristics

  • Amongst vegetation on low windswept mountain summits; the grey granules of the thallus grow long, white thread-like spines splayed at the tip
  • Often spreading to stony debris, mosses and other lichens.
