This is a non-sorediate species of high mountain gullies where it favours a gravelly soil and low temperatures. Thallus virtually confined to stalk-like pseudopodetia soundly bound to the soil in tight colonies with a grey tomentum and flattened phyllocladia, these turning K+ yellow, Pd + faint yellow. In Ireland, there is a record from the far north-east which should be regarded as dubious.

Key characteristics

  • Thallus grey, of grey tomentose-covered pseudopodetia and flattened phyllocladia
  • Thallus reactions: K+ yellow, Pd+ faint yellow; montane summits and gullies.
