This dark-brown, sparsely isidiate, regularly multi-lobed (to 8cm wide), foliose species occurs usually on trees in swamps by loughs, in ancient undisturbed woodlands and on mossy rocks. It is most commonly recorded from Irelandís humid south-western woodlands. Like S. fuliginosa (described elsewhere) it gives off a strong fishy smell when wet.

Key characteristics

  • Dark-brown, multi-lobed thallus becoming rather large (single lobed in S. fuliginosa)
  • The surface of the thallus on well-developed examples have isidia widely scattered, unlike S. fuliginosa where the isidia can often smother the lobes.
