This lichen forms spreading patches on walls, rotting tree stumps, logs and earth banks. The miniature golf-tee-like structures (cups) arise from scaly squamules which broaden from smooth stalks (podetia) into wide cups sometimes bearing in turn, small brown spots or dark brown discs along the margins. Both stalks and cups are covered in a fine, grey-green dusting of soredia (bundles of algae and fungal hyphae) the consistency of talcum powder. This is never granular or coarse in texture.

Key characteristics

  • Golf-tee-like cups covered from top to bottom in a fine, powdery soredia
  • Common on rotting wood and disturbed tree roots, especially around timber plantations.
