As the famous proverb goes, “all mushrooms are edible – some only once.” Take the Funeral Bell, for instance. This mushroom is nature's way of saying, "Don't even think about it."

Also known as the deadly skullcap, the Funeral Bell is the last ingredient you'd want in your risotto unless you're gunning for a Darwin Award. Growing on decaying conifer wood, this fungal fatality packs a punch with its lethal amatoxins. Ingest it, and you're in for a wild ride of liver failure, violent illness, and a date with the Grim Reaper.

Widespread across the Northern Hemisphere, its knack for blending in with edible lookalikes has led to about ten documented poisonings over the last century. Some of those poor souls were probably just looking for a little snack during a long walk.
