Mushrooms are very versatile - you can fill them, use them as a garnish for pizza, as a seasoning for sauces, use them in soups or use them as the main ingredient for savory meals. Mushrooms are also extremely suitable as a substitute for meat. Many mushroom enthusiasts enjoy collecting their own mushrooms in the wild, but not all wild mushrooms are safe to eat. One of the deadliest mushrooms is the green tuberous manite (Amanita phalloides). These and other Amanites attack the body by preventing the formation of certain proteins in the liver and kidneys. This leads to coma and death. The toxins of the green tuberous manite are located in all parts of the mushroom and are highly concentrated. That is why three grams of this mushroom can already be deadly. Because of the great danger, it is important that you know how to recognize the green tuberous manite.

To step

Look out for a whitish stem that is about 6 inches long with a large, round, bulbous, white and bag-like cuff. This is a remnant of the tissue that protected the mushroom near the base as it grew.
Measure the mushroom's hat and watch for a green or yellow color. The cap of this mushroom is about 6 to 15 cm wide and can be olive green, pale green or yellow, white or brown with one or more spots of white, thin covering tissue.
Dig a bit into the ground to reveal the bottom part of the mushroom's stem. This lower part, with the bulb and volva, is often buried in the ground around the tree to which the mushroom is attached. The sphere can break off over time and roll away, so even if you don't find it, you could still be dealing with an Amanita.
Look for a flat, wave-like brim on the hat. The cap of younger specimens is convex but flattens with age, creating a wave-like brim.
Watch out for numerous, white slats under the hat. The green knolamanite and other Amanites have white lamellae on the underside of the cap that are close together but do not extend all the way to the stem. The color of the lamellae is another way of recognizing a green tuberous manite. The slats of the tropical beech fungus are pinkish brown. Other mushrooms, such as species of the genus Agaricus, also have pink lamellae that later turn brown.
Place the mushroom's hat on a piece of paper to make a spore print and let it rest overnight. A green turnip manite will leave a white spore print. A tropical beech fungus will leave a pink spore hue.
Smell the flesh of the mushroom. A green tuberous manite smells a bit like rose petals. You can use this test if it is not visually possible to determine which mushroom you are dealing with.

Warnings

The green tuberous manite occurs in temperate areas from late summer to late autumn. In North America and Europe this is from the end of August to the end of November. In Australia and South America this is from the end of February to the end of May.
If you accidentally ate a poisonous mushroom of the Amanita family, you should seek help immediately. The longer you wait, the longer the toxins will be able to attack your body. Aggressive hydration (water consumption) is recommended. Amanita poisoning treatment begins with administering milk thistle extract to block the toxins that want to attack the liver. This is done along with an ovalbumin dialysis to remove the toxins. In some cases, a liver transplant will be necessary.
Know where the green tuberous manite occurs. This mushroom is native to Europe, where it is often found under oak and spruce trees. From there it has spread across North America and North Africa. Currently, this mushroom is also found in Australia and South America. The mushroom is strongly linked to oak and spruce and was unintentionally imported via seeds from these trees. The mushroom has also been noticed in some species of beech, birch, chestnut and eucalyptus, as well as in grassy areas. The mushroom lives in a symbiotic relationship with the tree, taking carbohydrates from the roots to which it is attached, and instead supplies magnesium, phosphorus and other nutrients to the tree.
- The green tuberous manite is often confused with the safe tropical beech mushroom (Volvariella volvacea). These two mushrooms are very similar, but there are some differences, as already described elsewhere in this article.
The green tuberous manite is not the only species of the Amanite family that is deadly. Other Amanites - Amanita virosa, Amanita bisporigera, Amanita ocreata, and Amanita verna, for example - are just as poisonous. The only difference with the green tuberous manite is that these varieties are white and have a drier cap. Amanita virosa is found in Europe and A. bisporigera and A. ocreata are found in the eastern and western United States, respectively. Some Amanites, such as Amanita Caesarea, are safe to consume, but unless you can distinguish them with certainty from their deadly relatives, it is better to avoid them.
