This is a gritty-textured trailing species which hangs like streamers of old bootlaces from old established trees. The core of each branch has a pinkish tinge with the medulla testing K-, Pd-, and C+ yellow-orange. The hanging portion of the thallus is spotted with coarse white swellings which burst to release granular soralia. In Ireland, the species is thinly distributed.

Key characteristics

  • Pendulous, coarse to the touch; branches with a pale pink centre and C+ yellow-orange reaction
  • Soralia granular giving the cortex a roughened appearance.
