5. Vegetable: Death Cap
Okay, it's not a vegetable. But it doesn't have a face and it grows in the ground, so I'm counting it as one for now. The Death Cap mushroom is found throughout Europe, hidden in plain sight, disguised as delicious, edible straw mushrooms. Don't get your fungi mixed up with this one though, as it is one of the deadliest toadstools out there, responsible for most of the human deaths involving mushroom poisoning. In a real dick move, it has been reported that Death Cap mushrooms have a pleasant flavour (so long as you like mushrooms), unlike most poisonous plants which will taste bitter in order to deter you from eating them. Symptoms of Death Cap poisoning include diarrhoea and vomiting (don't they all?), delirium, seizures, and coma. It will also cause damage to the liver, kidneys and central nervous system, producing jaundice, intracranial bleeding and eventually multiple organ failure. All sounds pretty grim. There is no real antidote and because the symptoms don't develop for some time, it's usually too late to go down the stomach-pumping route. In severe cases, the only treatment is liver transplant.
Fun Fact: Charles VI, Holy Roman Emperor until 1740, died after eating a dish of sautéed Death Caps. His death kicked off the
War of the Austrian Succession which had an estimated death toll of half a million people and changed the face of Europe forever. Thats a pretty big legacy for a mushroom.
