Fly Agaric (Amanita muscaria)
An easily recognised fungus that gives a flash of colour on the woodland floor. It should not be eaten.
People experimenting with drugs have dried fly agaric fruiting bodies in order to evoke hallucinations. Visual and auditory hallucinations. I have also read urine of Reindeer which have eaten fly agaric has been drunk by people in Lapland as a hallucinogenic – but how you get urine out of a Reindeer may be difficult!
