This attractive, rosette-forming, blue-grey, foliose species occurring on basic or mossy trees in well-established, undisturbed woodland, hazel coppice and willow swamp is one of the glories of the west of Ireland epiphytic lichen flora. The fan-like lobes support coarse to granular isidia along the margins and an icing of pruina over the lobe tips. The undersurface is covered in a felt of fine hairs. It is Pd + orange-red. Discs are rare. It occurs in oceanic areas of the west and north of Ireland mostly.

Key characteristics

  • The rosette form, blue-grey colour, and the granular soralia that may come to dominate the surface suggest the species
  • The rosettes overgrowing mosses are often broken or fragmentary; the Pd + orange-red reaction will separate it from similar species.
