Fuscidea lightfootii (Sm.) Coppins & P.James

Description: This is one of the commonest epiphytic lichens of boggy areas, such as wet woodlands and waterlogged hedgerows and is especially frequent on willow (Salix sp.) and heather stems, where it may be known by its size, colour and texture. The neat, circular patches, commonly less than one centimetre across, are comprised of pale olive green to grey convex areoles (wart-like granules). The dark grey discs are sparingly produced and lie flat among the granules like sucked wine gums.

Key Identification Features:

  • Small neat, circular patches of olive green granules (distinctive against brown sallow bark)
  • The dark grey discs with a paler edge never become convex.
