This non-isidiate species is rather like D. plumbea (described elsewhere), but unlike that taxon is rarely fertile. It also differs in the presence of spoon- or shoehorn-shaped schizidia which are the equivalent of lichen dandruff, the sloughed fragments being >1mm long with dark tips. In Ireland, it is rare, but occurs mostly along the north-west coastline and in County Mayo, growing in crevices along the shoreline where sea mists are frequent.

Key characteristics

  • Thallus resembling D. plumbea, discs rare but with abundant, surface schizidia peeling away from the thallus in the shape of a spoon
  • In crevices; those of coastal rocks especially.
