Formerly in the genus Melanelia, the thallus of this small foliose lichen is brown, mostly smooth and shiny and densely isidiate (covered in brown, solid, erect, peg-like outgrowths). The lower surface is pale brown. All spot tests are negative. This is a rare species currently known only from County Galway in Ireland. Usually on acid-bark trees with some nutrient enrichment.

Key characteristics

  • Brown, foliose thallus with negative spot tests and abundant small, solid and erect, coral-like isidia; twigs and bark of nutrient-enriched acid-barked trees
  • All lookalike species have either a C+ red medulla or hollow or flattened isidia.
