Brown Rollrim - Paxillus involutus

Description

As its name indicates, this fungus has a characteristic inrolled edge to its cap, which it loses only when fully mature. When young it is ochraceous to ochre-brown. The flesh turns brown when cut or damaged and if pressed the gills bruise red-brown. The gills can be separated from the cap flesh by pushing with a thumb-nail – a feature linking the genus to the Boletes. It is poisonous and should never be eaten.
