Do not pick and do not taste. It is on the map for reference — so you know it by sight.
A vivid red cap flecked with white, white gills, and a white stem with a ring and a bulbous base girdled with bands. It contains ibotenic acid and muscimol, which cause nausea, confusion, hallucinations and delirium. Deaths are rare, but the poisonings are serious. It is on the map so that you know it by sight, not so that you pick it.

Yellow gills and a yellow stem, and no flecks on the cap. Edible — but check the gills, not the cap colour: rain washes the flecks away.
