About Gyromitra esculenta in brief
Gyromitra esculenta is a popular delicacy in Scandinavia, Eastern Europe, and the upper Great Lakes region of North America. When consumed, the principal active agent, gyromitrin, is hydrolyzed into the toxic compound monomethylhydrazine. The toxin affects the liver, central nervous system, and sometimes the kidneys. Symptoms of poisoning involve vomiting and diarrhea several hours after consumption, followed by dizziness, lethargy and headache. Severe cases may lead to delirium, coma and death after five to seven days. The fungus was first described in 1800, by mycologist Christian Hendrik Persoon. It is a member of a group of fungi known as “false morels”, so named for their resemblance to the highly regarded true morels of the genus Morchella. The more distantly related ascomycete mushrooms of the. genus Verpa, such as V. bohemica and V. conica, are also known as false morels, early morels or thimble morels; like the Gyrom itra, they are eaten by some and considered poisonous by others. The poisonous qualities of G. Esculenta may be reduced by cooking, but possibly not enough to prevent poisoning from repeated consumption. It may be sold fresh in Finland, but it must be accompanied by warnings and instructions on correct preparation. Although popular in some districts of the eastern Pyrenees, it is prohibited from sale to the public in Spain.
The mushroom is known by a variety of common descriptive names such as “brain mushroom, ” elephant ears, or “beefsteak mushroommorel,” although beefsteak mushroom can also refer to the much less toxic basidiomycete Fistulina hepatica. It was originally described as Helvella esculenta, and gained its current accepted binomial name when the SwedishMycologist Elias Magnus Fries placed it in the genus Gyromitsa in 1849. The genus Gy Romitsa had been classically considered part of the family Helvellaceae, along with the similar-looking elfin saddles of the gener Helvellas. The most related genus is Discina, which also contains Pseorhizina and Hydrya in the family Discryinaceae in the Pezizales. The species is now included in the Family Discrya, forming a clade forming a genus called Discina Discina and the genus Discina. It can reach 10 centimetres high and 15 cm wide, perched on a stout white stipe up to 6 cm high. Specimens from California may have more reddish-brown caps and stipe at several points, the cap is 3–6 cm–6–cm stipe is 3-6 points, and is the colour of various chestnut-brown or purplish baynut. The cap may be various shades of reddish chestnut.
