One of Irelandís most attractive lichens H. leucomela or ciliate strap-lichen is an easily recognised species with white strap-like lobes (to 3mm wide) bearing long, black hairs (cilia) projecting from the edges. It is rare and currently only known from sites in west Cork and County Kerry where it grows among mosses and rocks by the shoreline. In west Cork, it will also grow on trees in wet woodland particularly in sallow swamp.

Key characteristics

  • Thallus of white, strap-like lobes with long whiskery cilia attached to the edges
  • Among mossy debris on sea cliffs, and on willow trees in swampy sites near the coast.
