How about these for classic fairytale toadstools? You can almost see one of the little people sitting on the top of them, can’t you? Fly agaric is the correct name. It’s not for eating, in fact a good rule is not to eat red mushrooms. Fly agaric is a hallucinatory mushroom and eating it is said to give you the sensation of flying. It is a therefore part of many a shaman’s toolkit.
There are tales of reindeer eating the mushroom and staggering around trying to fly. Maybe Rudolf had eaten one too many!
