This widely distributed plant of siliceous rocks and churchyard memorials resembles Melanelia fuliginosa var. glabratula, but differs in its dark brown to almost black-brown colour, tightly packed, shiny isidia and preference for acid rock rather than bark.

Key characteristics

  • Forms dark brown to almost black patches on acid rock; rare on bark
  • Small shiny, stick-like isidia pack the centre of the thallus tightly, more so than in related species.
