This species is very like the common upland species U. cylindrica (described elsewhere) but differs in the absence of marginal hairs (cilia) and the markedly ridged and icing-sugar coated (pruinose) centre to the thallus. In Ireland, this species is only known from the far south-west and County Wicklow.

Key characteristics

  • Like U. cylindrica but without marginal cilia; very crumpled and ridged, pruinose
  • Point of attachment central, medulla C+ red.
