This unusual lichen of periodically immersed rocks and mosses besides streams and loughs is composed of overlapping squamules (scales), grey-green to pale brown, divided into lobes. The discs (perithecia) are sunken into the thallus and show up as small, rounded spots or buttons. Under the microscope, the spores will be seen to be within the range 31-40µm long. Present in Ireland in north Kerry, Connemara and around the turloughs of The Burren, County Clare.

Key characteristics

  • Grey-green changing to pale brown when dry; forms a layer of overlapping squamules over mosses on periodically inundated boulders
  • Perithecia sunken below thallus and visible as raised spots; two-spores/ascus.
