While false morels are deadly poisonous when raw, in some parts of the world they are considered edible (and delicious) if properly parboiled.
False morels contain gyromitrin, a volatile water-soluble hydrazine compound that decomposes in the body into methyl hydrazine.
It acts as a hemolytic toxin as well as damaging the liver and the central nervous system.
Due to its volatility, even the mere presence of fresh false morels in a poorly ventilated space may cause gyromitrin poisoning symptoms such as headache, dizziness and nausea.
Consuming raw or incorrectly prepared false morels can result in catastrophic liver failure and death..
