‘Ragged pseudocyphellaria’ is a very rare foliose species and good specimens are required for certain identification. The yellow-brown to greenish lobes are noticeably concave with margins crisped and uneven, often densely grey-blue isidiate, whiter where eroded. When well-developed, the isidia clearly distinguish this species from the similar P. intricata which is sorediate. In Ireland, the species is restricted to County Kerry. It grows on mossy rocks and old tree branches in oceanic woodlands near the sea.

Key characteristics

  • Mostly like P. intricata but with grey-blue isidia along the lobes
  • The isidia may be simple, cylindrical or branched; mossy boulders and old mossy trees in humid woodlands.
