Find a good stand of bog myrtle and you will find this lichen. Look for it on the woody stems where the small (0.2-0.4mm diam.), olive green or bluish to black, broadly spherical discs (perithecia) pimple the bark. For confirmation, look out for the white border which surrounds every disc like a silver halo. Northern and western Ireland.

Key characteristics

  • The abundant discs with an olive green or blue tinge
  • Discs surrounded by silver-white halo.
