This species grows in abundance at the base of old, large, acid-barked trees (including evergreens) and is easy to recognise. The thin, smooth thallus is densely spotted with neat, white, globose pycnidia (0.2-0.5mm diam.) covered in snowy pruina. To the observed it can resemble a white rash at the base of a tree. L. subabietina may grow to cover ivy stems or stones and once in situ is quick to spread. Reactions: pycnidia: C-. The similar L. abietina (described elsewhere) has more slender pycnidia: C+ red. Dry, shaded, acid bark. Thinly scattered in Ireland, probably under-recorded.

Key characteristics

  • Smooth, grey-white thallus, densely pimpled with numerous, white-pruinose pycnidia, C-
  • Dry hollows at the base of old, standing acid-barked trees especially oak and tall, shady evergreens, for example, yew.
