When in south-west Ireland, look for this species on elder, elm or Buddleja. The grey thallus is extremely thin and the discs are small (to 0.3mm diam.). In size and shape it could by mistaken for Amandinea punctata or Catillaria nigroclavata (described elsewhere). Under the microscope the disc will be seen to have a brown hypothecium. The bullet-shaped spores have a thick septum.

Key characteristics

  • Thallus grey; very small discs with brown raised edge; spores Rinodina-type, bullet-shaped
  • On soft basic bark.
