Similar species

  1. Amanita citrina var alba usually retains velar fragments on the cap; it has the sharp smell of new potatoes rather than a sweet odour.
  2. Young caps of Amanita virosa could be collected by accident when gathering edible Agaricus species; gills of Amanita virosa are pure white, whereas the Agaricus species have gills that are initially pink and later brown.
