This is a minute, common species of basic twigs and branches, especially elder and ash. From the greyish thallus arise numerous, very small, grey-margined, pink-brown discs becoming convex and rounded with age. Most twigs snapped from the terminal 50cm of an ash branch should have it sprinkled across the bark, but you will need a hand lens to see its form and structure.

Key characteristics

  • Mainly on twigs of soft basic-barked trees: ash, sycamore; also rough bark of elder where it will occurs on the main stems
  • The numerous, very small, convex, pinkish discs serve to indicate this common species.
