Large striking foliose lichen forming rounded rosettes of wavy lobes dark brown when wet, greener when dry crammed with abundant, tiny, leaf-like folioles; lower surface with a thin fur of tomentum. The discs are red-brown and unmistakable with abundant folioles around the exciple (rim), like petals round a chrysanthemum head. It occurs on mossy tree trunks or fallen trees in moist woodlands, often by loughs. In Ireland, it is present in the south and west only.

Key characteristics

  • Thallus dark brown, thinly furry below, leafy to 10cm or more, of wavy rosettes crisped with folioles
  • Discs red-brown ringed with folioles; mossy trees by waterbodies.
