The small, wrinkled, squashy thalli (to 1cm thick, when wet) of this distinctive epiphyte form tiny, orbicular cushions, on mossy trees in the west, accompanied by numerous discs. The spores are worm-like; 10- to 15-septate. It is entirely restricted to the oceanic woodlands of Counties Kerry, Cork, Galway and Fermanagh. In addition, there are early twentieth-century records from Counties Sligo and Leitrim. Most of the populations are small.

Key characteristics

  • Small, wrinkled, pulpy thallus with abundant discs; on mossy trees in the west
  • Spores distinctive, worm-like, with up to 15 partitions (septa).
