One might expect to come across this species growing at the grassy edges of disturbed heaths or on formerly metal-contaminated soils. However, few people appear to have seen it in Ireland; it has only been recorded on a handful of occasions. It is similar to the common P. hymenina but differs quite emphatically in the more spectacular slashed or cracked lobes which suggest that someone has been let loose with the carving knife. In good material, the short-stalked discs take on a red-brown, almost blackened hue. Occasionally, the thallus is C+ red. In Ireland, the lichen is poorly known.

Key characteristics

  • Like P. hymenina (described elsewhere) but with thallus distorted by thick crack-like slash marks
  • The elongate, fingernail- shaped discs are almost black.
