This rare Umbilicaria presumed to have been collected during the nineteenth century from Tonelagee in the Wicklow Mountains has a single lobed thallus with a brown, occasionally grey, upper surface and a dark slightly roughened underside with no pink pigmentation. The black discs occur mostly away from the centre of the thallus and have a thick rim and a prominent central pillar of sterile tissue. It is known to favour water seepage cracks. It should be avidly searched for in the Wicklow Mountains.

Key characteristics

  • Single lobed brown to grey thallus
  • Discs near the edge of the thallus, black with a central pillar of tissue.
