The dark brown to black, occasionally clustered discs (to 1.2mm diam.) of this lichen are best searched for among the loose, calcareous rocky slopes of the uplands. The grey to pale brown thallus gets in among the mosses from where it may spread later to looser substrata. It attracts attention through its discs which keep their margins throughout their life. Northern and western Ireland.

Key characteristics

  • Over mosses and dead plant material on rocky calcareous screes and slopes
  • Thallus pale brown or grey, gauzy; brown-black discs with persistent, narrow margin.
