This rather insignificant crustose species grows best on elder bark but can sometimes be found among the low-vegetation of sea cliffs. Its most distinctive feature is the tiny black, conical pycnidia which through a lens look like an up-ended filter funnel. It is common on suitable substrates throughout Ireland, and is probably greatly under-recorded.

Key characteristics

  • It is easily recognised by the tiny spiked pycnidia that look like upturned funnels
  • It is a soft-bark species, so learn it first by searching elder bushes growing along waysides.
