The thallus of this crustose species has a C+ pink, scurfy brown-black cortex giving it an almost leprose feel, rather like a fluffier, but more coherent version of Placynthiella icmalea which is also C+ red. It frequently grows over or among other lichens on sunny, exposed schistose or weakly siliceous rocks. Currently known from western Ireland, but is likely to be more widespread.

Key characteristics

  • Thallus like a scurfy black-brown stain; lichenicolous, C+ pink (sometimes also K+ yellow to red and Pd+ yellow)
  • Exposed, weakly acid rocks; upland.
