Very rare and recorded only from oak in County Down, L. chlorotiza is a plant of shaded tree trunks by rivers and woodland ditches. The thallus is green and scurfy with immersed, pink-orange discs (0.1-0.3mm diam.) that have a thin ragged-looking margin. Damp or shaded, base-rich trees including old oaks with a spongy bark.

Key characteristics

  • Thallus in shade: bright green with immersed pink-orange discs
  • Shady trees by rivers or slow-moving woodland dykes and ditches.
