This Thelotrema resembles the much commoner T. lepidinum in general appearance, but has a grey-green (not creamy) thallus and discs with a narrower opening. The large-sized spores are grey-brown when mature, not colourless as in T. lepidinum. It grows in boggy, long-undisturbed oceanic woodlands, especially on twigs of hazel; also on ash. Western Ireland.

Key characteristics

  • Grey-green thallus, usually on twigs rather than broad areas of exposed bark
  • Spores large and dark-coloured, sometimes visible with a lens on the surface of the discs.
