All Umbilicaria lichens are foliose and attached to the substratum by a stout centre called an umbilicus. U. polyphylla is many-lobed, with a smooth and glossy chestnut upper surface and sooty black lower surface without attachment structures (rhizinae). It occurs sparingly on mountain rocks and boulders in the north and east of Ireland.

Key characteristics

  • Many-lobed, with lobes ascending, chestnut and shiny above, black and matt below
  • Lower surface without rhizinae; tops of boulders.
