Irish Distribution

Widespread, but commonest in the west and north.


  • Generally common in woodland on acid or neutral soils
  • Waterlogged peat is not favoured but peatland lagg woods and the drier margins of raised mires are commonly well populated
  • May also be found in calcareous flushes in peaty terrain
  • There are several records for coastal dune systems and it seems to be more tolerant of drier conditions than C. edentula

Red List status

  • Least concern (lc).
