Action Plan Summary

Current Status

National Status

  • Nail fungus is possibly the rarest fungus in Europe. Formerly widespread in the UK, it is now confined to the New Forest, and is otherwise found only in a few places in south-east Europe. The fungus is listed on the GB Red List as endangered and in the IUCN/WCMC Red Data List as undetermined.
  • The vast majority of records (and all recent ones) are from Hampshire but a few of the older records are from other regions of England.

Norfolk Status

  • Possibly a single extant site at Holme within the North Norfolk Natural Area. (Report of it occurring at Holme in the 1960s.)
  • The publicly accessible BMS Database does not usually include exact localities but the following Norfolk records for Poronia punctata appear on the database:

1873 Hunstanton
1874 Yarmouth
1941 vc 27
1944 vc27
