What do Amatoxins do?
The amatoxins interfere with protein synthesis and cause liver failure. Other Amanita species such as Amanita smithiana contain a renal toxin, and Amanita muscaria and Amanita pantherina have isoxazole toxins, causing alterations in mental status but no liver or renal injury.
What Muscarine does to the body?
Muscarine poisoning is characterized by miosis, blurred vision, increased salivation, excessive sweating, lacrimation, bronchial secretions, bronchoconstriction, bradycardia, abdominal cramping, increased gastric acid secretion, diarrhea and polyuria.
How much Amatoxin is lethal?
Ingested amounts as low as 0.1 mg/kg are sufficient to be lethal [11]. A single full-grown specimen of A. phalloides, weighing 20 g, contains about 5–8 mg of amatoxin and is, therefore, potentially lethal.
Where is Amatoxin found?
Amatoxin is the collective name of a subgroup of at least nine related toxic compounds found in three genera of poisonous mushrooms (Amanita, Galerina and Lepiota) and one species (Conocybe filaris) of the genus Conocybe. From the amanita, the most notably is the death cap (Amanita phalloides).
What does death cap taste like?
They are common in Western Washington, and were found recently on the University of Washington Seattle campus. The death cap mushroom has no distinctive odor or taste and resembles other nontoxic varieties. Consumption of the Amanita mushroom causes most of the deaths from foraged mushrooms worldwide.
What does a death cap look like?
To identify a death cap mushroom, look for a mushroom with an off-white cap, which may have a green or yellow tint. You should also measure the cap’s diameter. If it’s between 3 and 6 inches, which is the usual size for a death cap, err on the side of caution and don’t pick it.

Can you survive amatoxin poisoning?
Amatoxin poisoning is characterized by a long asymptomatic latency period followed by the gastrointestinal (GI) symptoms, transient improvement, severe hepatic and renal toxicity, and finally death. It is a medical emergency, which can cause serious illness and death of the individual.
How do you detect amatoxin?

What type of drug is Amatoxin?
The major amatoxins, the alpha-, beta-, and gamma-amanitins, are bicyclic octapeptide derivatives that damage the liver and kidney via irreversible binding to RNA polymerase II. Methods: The mycology and clinical syndrome of amatoxin poisoning are reviewed.
