Don’t mistake it with

  • Older specimens with their pale caps are easily mistaken for the Deceiver Laccaria laccata, but the Amethyst Deceiver can be distinguished by the purple colouring that remains on the gills and the stipe
  • The Lilac Bonnet Mycena pura is another purple-lilac tinged mushroom, but has pale gills, more of a pink appearance, and the stem is not fibrous
  • The Lilac Fibrecap Inocybe geophylla var. lilacina is also similar, but is paler overall and does not have the purpley gills

Did you know?

The name ‘amethyst’ refers to the purple colouring of the young mushrooms and Laccaria means ‘lacquered’, referring to the shiny appearance of the fresh caps.
