Gyromitra esculenta, or the False Morel, is a Spring mushroom that contains the toxin and carcinogen gyromitrin, which makes it illegal to sell and cook in countries around the world. In Finland, however, it is considered a delicacy.
False Morel mushrooms have historically been consumed in northern Europe for centuries, but as chemistry and medicine evolved, it became somewhat of a forbidden fruit due to the dangers of consuming even small amounts of gyromitrin. Symptoms associated with the ingestion of this known toxin and carcinogen include severe headaches, vomiting, nausea, extreme dizziness, diarrhea and, if the damage to the liver is too serious, even death. Their sale in countries like Sweden and Norway was made illegal years ago, but in Finland people still eat it with gusto.
