This species is very rare in Ireland, growing only at one site in County Kerry on willow. The crustose thallus is always immersed in the bark so all that is visible are the tiny, Gyalecta-like concave discs. It occurs mostly on damp, spongy tree bark (usually oak) by ditches in old woodlands under a dappled canopy. The spores are beautiful, spindle-shaped, 8- to14-septate.

Key characteristics

  • Thallus inapparent; discs like Gyalecta on the smooth areas of spongy bark of old woodland trees by ditches and streams
  • Spores spindle-shaped, 8- to 14-septate; never muriform.
