Without a doubt, the most iconic toadstool of them all, the Fly Agaric features in fairy-tales and folklore as a home for magical creatures. Biologically speaking, their role in nature is pretty magical too: in the birch woodlands where they grow, fly agaric helps trees by transferring nutrients into their roots.

Although reports of toadstool-related deaths are rare, eating a fly agaric can cause stomach cramps and hallucinations, which makes for a pretty grim combo. If you have a problem with flies in your house, however, this toadstool can be good to have around. Historically, the caps were broken up and sprinkled into saucers of milk. It's known to contain ibotenic acid, which both attracts and kills flies – hence the name.
