This is the form often referred to as S. canariensis dufourii which is quite different from the large-sized, rare green form S. canariensis canariensis. The dufourii form is more akin to other fishy-smelling Sticta species, grey-brown when dry, darker brown when wet and similarly sized. It differs in the lobules and flattened isidia which grow along the tips of the lobes (shredded edges) and in the grey colour of the larger lobes which appear to have a translucent netted surface (marbled) as they dry. Damp sheltered situations: lough edge woodlands, damp sallow swamps, mainly western in Ireland but also with a number of scattered localities in the east.

Key characteristics

  • Grey-brown dry thallus, browner when wet; flattened isidia and small lobules along the lobe edges
  • As lobes dry they can appear netted.
