Evidence for the presence of this species in Ireland is based on an old record from North Kerry, but if it still occurs in the vice county it will be in the Reeks range, for this is a montane species of summit soils and low, mossy vegetation. The grey to pale brown verrucose thallus discs <1mm diam. and brown cephalodia present are key characters. A section through the disc, however, will reveal its microscopic characteristics: red-brown hypothecium, lack of purple pigmentation and tendency towards divisions (septa) within the spores.
