There are just fourteen records for Cortinarius pratensis currently listed on the FRDBI database [February, 2018]. The above specimens were located in a West Sussex sand dune system during a detailed search of the area in December 2017. My thanks to Nick Aplin of the Sussex Fungus Group for confirming their identification. It’s a fairly nondescript brown toadstool but certainly one to look out for if you enjoy little brown jobs …
