This is a rare, shrubby-filamentous species of old, humid, western-oceanic woodlands. It has a minutely woven, delicate thallus of short, branched filaments which form tiny blue-grey cushions often attached to liverworts such as Frullania tamarisci. It grows in the woodlands of Counties Kerry and Cork where it favours alder.

Key characteristics

  • Tiny shrubby, epiphytic species composed of blue-grey, interwoven branched filaments
  • Overgrowing the liverwort Frullania tamarisci on alder but also hazel, ash and oak in the old, humid-oceanic woodlands of the south-west.
