Nature Notes: Typically found in damp areas such as among mosses and decaying wood, on old walls and mature trees. The sites also tend to be undisturbed and sheltered. The lichen contains the photobiont Nostoc; this adds the dark blue-grey colour to the species when wetted. Found mainly in the coastal counties of the west of Ireland, especially Cos. Kerry, Mayo and Donegal.
