C. subflaccidum is somewhat similar in appearance to C. flaccidum (described elsewhere) but there the similarity ends as the latter is predominantly a lichen of aquatic habitats. C. subflaccidum is an epiphyte of mature basic-barked trees often confined to rather sheltered situations. The near black thallus is covered with tiny pebble-like isidia giving the upper side a scurfy appearance. Sheltered, well stocked country gardens with mature ash trees would be promising search areas. Western Ireland.

Key characteristics

  • Near-black ‘jelly-lichen’ with flat lobes covered in pebble-shaped isidia
  • On mature, basic-barked trees in damp, relatively sheltered habitats.
