Allographa pauciloculata Coppins & P.James

Description: This rare ‘scripture’ lichen is known from Wexford, Clare and from the Lough Eske area of County Donegal where it grows on holly in moist woodland. The silvery-grey thallus produces very small discs called lirellae (0.5-1.5mm diam.) that are superficial, squat or elongate, resembling a very diminutive version of G. ruiziana. It is unlikely to be confused with other members of this genus, but might be overlooked as a bark fungus. The spores are less than eight-celled, usually three to six.

Key Identification Features:

  • Miniature G. ruiziana in appearance on a silvery thallus
  • On holly in boggy woodland.
