Brown Rollrim - Paxillus involutus


    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.

    It is found in deciduous woodland, particularly on Birch, and in other wooded areas where Birch is present.
