Do not pick and do not taste. It is on the map for reference — so you know it by sight.

The deadliest mushroom in Europe: most fatal poisonings are laid at its door. An olive-green cap with radial fibres, gills that are always white, a ring on the stem and a white bag-like volva at the base. Amatoxins survive both cooking and drying; symptoms arrive six to twenty-four hours later, by which time the liver is already damaged. One fruit body is enough to kill an adult.

Confused with

  • Charcoal burnerRussula cyanoxantha

    An edible russula, with neither ring nor volva. Look at the base of the stem — lift the whole mushroom out rather than cutting it.

  • Caesar's mushroomAmanita caesarea

    In the "egg" stage they look identical from outside; cut open, the Caesar's cap is orange and the death cap's is white or greenish.

  • Field mushroomAgaricus campestris

    A field mushroom's gills turn pink and then black with age, and there is no volva; the death cap's gills stay white for ever.
