Death Cap Toxic?

Updated 2026-03-06| 3 min read| 4,318 found this helpful
Amanita phalloides (Vaill. ex Fr.) Link
1

Its amatoxin toxins cannot be destroyed by cooking, freezing or drying, and remain active for more than 10 years in dried specimens.

2

Poisoning progresses in 4 phases, with a 6-12 hour latent period with no symptoms before gastrointestinal issues and eventual organ failure.

3

Even small ingestion amounts can cause fatal liver and kidney damage, immediate medical/veterinary attention is critical after consumption.

FAQ

Is Death Cap toxic to Humans?

4 progressive phases: 6-12h latency with no symptoms, then 6-24h gastrointestinal distress (vomiting, abdominal pain, diarrhea, lethargy, anorexia), then 12-24h apparent recovery followed by fulminant liver and kidney failure. (Severe)

Is Death Cap toxic to Cats?

Same 4-phase progression as dogs, with high risk of irreversible liver and kidney damage if untreated, potentially fatal. (Severe)

Is Death Cap toxic to Dogs?

4 progressive phases: 6-12h latency, then gastrointestinal symptoms, apparent recovery, then liver/kidney failure; dogs have higher amanitin absorption rate than rodents like mice and rabbits. (Severe)

Is Death Cap toxic to Horses?

Limited species-specific data available, but ingestion is expected to cause severe gastrointestinal symptoms, liver and kidney damage, and may be fatal. (Severe)

First Aid & Prevention

First 30 Minutes

  • • Induce vomiting immediately if the affected individual is conscious and ingestion occurred within the last 1-2 hours.
  • • Administer activated charcoal as soon as possible to reduce toxin absorption in the gastrointestinal tract.
  • • Do not give any food, drink or home remedies unless explicitly directed by a medical or veterinary professional.

Contact Vet Immediately

  • • If you suspect ingestion of this mushroom, even if no symptoms have appeared yet.
  • • If symptoms like vomiting, diarrhea, abdominal pain or lethargy appear after possible wild mushroom exposure.
  • • If liver or kidney function test results are abnormal after suspected mushroom ingestion.

Prevention

  • • Avoid consuming any wild mushrooms unless they are 100% identified as safe by a certified mushroom identification expert.
  • • Keep children and pets away from areas where wild Amanita family mushrooms are known to grow.
  • • Discard any foraged mushrooms that have ambiguous identification features to avoid accidental poisoning.

Treatment & Prognosis

  • • Repetitive administration of activated charcoal to limit further toxin absorption and interrupt enterohepatic circulation of toxins.
  • • Administer medications including cyclosporin A, rifampicin or silibinin to prevent liver uptake of toxins (for dogs: 50mg/kg silibinin intravenously at 5 and 24 hours post-ingestion).
  • • Provide supportive care including fluid therapy, close monitoring of liver and kidney function, and targeted management of organ failure symptoms.

Professional Toxicology

Scientific NameAmanita phalloides (Vaill. ex Fr.) Link
AliasesDeadly amanita、Death angel
Toxicity Grade
HumansSevere
CatsSevere
DogsSevere
HorsesSevere
Target Organs
LiverKidneysGastrointestinal tract
Mechanism of Action

• Amatoxins are absorbed in the gastrointestinal tract, transported to the liver where they inhibit RNA polymerase II, stopping protein synthesis and causing liver cell necrosis.

• Toxins undergo enterohepatic recirculation, prolonging their toxic effects, and also cause direct damage to kidney tubule cells leading to kidney failure.

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Rat: Comparatively resistant to the toxic effects of amanitin, with much lower risk of fatal poisoning than companion animals like dogs and cats.
Mouse: Has lower gastrointestinal absorption rate of amanitin compared to dogs, but ingestion can still cause severe poisoning and organ damage.
Rabbit: Has lower gastrointestinal absorption rate of amanitin compared to dogs, but consumption is still potentially harmful and may cause organ damage.
Confusion Risk

The following plants look similar and may be confused:

Agaricus species (Field mushrooms) Agaricus sp.
Most Agaricus species are edible, but they are often confused with death caps; key difference: toxic lookalike Agaricus xanthoderma stains yellow when the stem is bruised and has a distinct carbolic smell, and no volva (cup at stem base) like death caps.
Gold Knight Tricholoma Tricholoma auratum
Toxic mushroom with a similar greenish cap hue to death caps; key difference: it lacks the characteristic volva at the stem base and white gills that Amanita phalloides has.
Yellow Knight Tricholoma Tricholoma sejunctum
Toxic greenish-yellow mushroom often mistaken for death caps; key difference: it has no prominent volva at the stem base, a feature unique to Amanita family mushrooms.
