Rare on sallow in Killarney National Park, this species is often overlooked for Pertusaria pupillaris (Pd+ rust-red) or similar sorediate crusts. However, the soredia of this species are Pd+ pale yellow. The small discs, when present, are a beautiful scarlet red. When these are present, it is unmistakable.
