This is a rare crustose species with a thin, cracked or warted, pale grey to brown-grey thallus and brown to black discs. There is little to distinguish it other than the dry, heathland-type habitat of decaying turf, heather stems and rabbit pellets. Under the microscope, the clincher is the (one-) to three- (five-) septate spores which is unique to this species in Ireland. It has only been seen in western County Mayo but should be searched for elsewhere, especially near the coast.

Key characteristics

  • Grey crust with small (0.3-0.85mm diam.) discs growing on rabbit pellets, heather stems or decaying turf near to the sea
  • Spores with > 2 locules (spore chambers), one- to five-septate.
