In this article, we will discuss the seven most poisonous mushrooms in the world.

1. Destroying Angel: This mushroom is mainly found in Europe and is highly toxic and deadly. It has a pungent smell that repels people.

2. Autumn Skullcap: Galerina marginata, also known as autumn skullcap, can be found in temperate places around the world. It looks like a hallucinogenic fungus but is quite toxic. It can be tricky to differentiate from other mushrooms, especially since these tiny mushrooms may be growing in the same area.

3. Amanita phalloides: Also known as the death cap mushroom, this species is one of the most poisonous mushrooms known. It is widely distributed in Europe and grows symbiotically in deciduous trees in the form of mycorrhizae.

5. Hooded False Morel: This brown saddle mushroom is often confused with a delicious, edible mushroom that must be cooked before eating. It contains the toxin gyromitirin, which the body converts to methylhydrazine, one of the ingredients in rocket fuel. It is a serious carcinogen and can have a great impact on the human body.

6. Gyromitra esculenta: This poisonous and inedible fungus is widely distributed in Europe and North America. It often causes gastrointestinal discomfort and even coma. Although it is a poisonous and inedible fungus, it is still a popular delicacy in Scandinavia, Eastern Europe, and the northern part of the five major lakes of North America.

7. Fly Agaric: This mushroom is famous for its hallucinatory toxicity. The edge of Fly Agaric has obvious short ribs, the surface is bright red or orange, and there are white or yellowish granular scales.

Symptoms include severe nausea, vomiting, abdominal pain, diarrhea, mental confusion, sweating, chills, muscle twitching, slow pulse, difficulty breathing or trismus, dizziness, and confusion.
