The Death Angel or Destroying Angel mushroom is a deadly fungus that grows in woodlands, fields, and lawns. It is a beautiful, large white mushroom with a ring on the stalk and a sac-like cup around the base. This mushroom is one of the most toxic known mushrooms, containing amatoxins that inhibit protein synthesis and cause liver and kidney failure. The toxins in Death Angel mushrooms can also poison a baby in the breastmilk of a mother who has consumed them. The symptoms of poisoning include severe stomach cramps, vomiting, diarrhoea, and convulsions, and they can appear several hours after ingestion. If left untreated, Death Angel poisoning can be fatal, and liver transplantation may be required for survival.

What You'll Learn
Angel mushrooms are deadly due to amatoxins
Angel mushrooms, also known as Death Angels or Destroying Angels, are deadly due to the presence of amatoxins. These toxins inhibit RNA polymerase II and III, which is crucial to protein synthesis. This results in the prevention of the formation of enzymes, membrane receptors, structural proteins, peptide hormones, and other essential proteins.
The poison responsible for the fatalities caused by Angel mushrooms is a pair of peptides called amatoxins, which include alpha-amanitin and beta-amanitin. Alpha-amanitin kills liver cells and passes through the kidneys to be recirculated and cause more damage. This can lead to liver failure if not treated immediately. Additionally, amatoxins can cause damage to vital organs, resulting in severe stomach cramps, diarrhea, vomiting, delirium, convulsions, and abdominal pains. These symptoms can last for a few days, followed by a brief recovery period before ending in death from kidney and liver failure.
Angel mushrooms are often mistaken for edible fungi, such as button, meadow, or horse mushrooms. They are characterized by their white gills and stalks, with a cap that can be pure white or have yellowish, pinkish, or tan hues. They are commonly found in woodlands, lawns, or grassy meadows near trees or shrubs.
The toxins in Angel mushrooms are potent and recirculate in the human body, making them extremely dangerous. It is recommended to seek immediate medical attention if Angel mushroom poisoning is suspected, as treatment options such as dialysis, liver transplantation, or the administration of silibinin may be required.

Amatoxins inhibit protein synthesis
Angel mushrooms, also known as "Destroying Angel" or "Death Angel", are among the most toxic known mushrooms. They are characterized by their white colour and gills, and can be commonly found in woodlands, lawns, or grassy meadows near trees or shrubs. They can be easily mistaken for edible mushrooms, making them extremely dangerous.
The primary toxin in Angel mushrooms is amatoxin, which is a potent and selective inhibitor of RNA polymerase II (RNA Pol II), a vital enzyme in the synthesis of messenger RNA (mRNA), microRNA, and small nuclear RNA (snRNA). Amatoxins are cyclic peptides that are synthesized as 35-amino-acid proproteins, and they have a strong inhibitory affinity for RNA polymerase II. This enzyme is crucial for the synthesis of mRNA, which serves as a template for protein synthesis. Without mRNA, cell metabolism stops, leading to cell death and apoptosis.
At the molecular level, amatoxins cause damage to cells by creating perforations in the plasma membranes, resulting in the displacement of organelles from the cytoplasm to the extracellular matrix. The liver is the principal organ affected by amatoxin poisoning, as it is the first organ encountered after absorption in the gastrointestinal tract. Amatoxins are rapidly absorbed by liver cells, leading to centrilobular hepatic necrosis and fatty degeneration, which can cause liver failure within 48 hours.
In addition to liver damage, amatoxins can also cause gastrointestinal distress, including stomach cramps, vomiting, and diarrhea. These symptoms typically occur 6-12 hours after ingestion, followed by a remission stage where the patient feels better as the stomach is emptied. However, if left untreated, the patient may fall into a coma or die due to irreversible liver and kidney failure, central nervous system deterioration, dehydration, and impaired kidney function.
Treatment for amatoxin poisoning includes high-dose penicillin, intravenous vitamin K, fresh-frozen plasma, and supportive care for hepatic and renal injuries. Silibinin, a product found in milk thistle, is also a potential antidote, but more data is needed to confirm its effectiveness.

Poisoning symptoms include vomiting, diarrhoea, and abdominal pain
The destroying angel, or death angel, is a deadly mushroom that causes severe poisoning. It is a member of the Amanita family, which contains over 900 species, nine of which produce amatoxins that are harmful to humans. Amatoxins are the toxins responsible for the majority of deaths due to mushroom poisoning. They inhibit RNA polymerase II and III, which is crucial to protein synthesis.
Poisoning symptoms typically appear 5 to 24 hours after ingestion, and include vomiting, diarrhoea, and abdominal pain. These initial symptoms are followed by more severe complications, such as delirium, convulsions, and organ failure. The toxins in the destroying angel mushroom cause irreversible damage to the liver and kidneys, which can lead to death if not treated quickly. As little as half a mushroom cap can be fatal for an adult.
The destroying angel is often mistaken for edible mushrooms, such as the button, meadow, or horse mushroom. It is characterized by its white colour, gills, and stalk. It usually grows in woodlands, lawns, or grassy meadows near trees or shrubs. The mushrooms appear in the spring and summer, and can be found in various parts of the world, including Europe and North America.
If you suspect mushroom poisoning, seek immediate medical attention. Treatment options include fluid and electrolyte replacement, oral activated charcoal, lactulose, IV penicillin, and hemodialysis. In severe cases, a liver transplant may be necessary.

Treatment includes silibinin, NAC, and liver transplants
Angel mushrooms, also known as Death Angel mushrooms, are highly toxic and can cause severe, irreversible damage to vital organs, including the liver and kidneys. Amatoxin poisoning from Death Angel mushrooms can be life-threatening and requires immediate medical attention. Treatment for amatoxin poisoning involves mitigating the effects of toxins, protecting the liver, and, in severe cases, liver transplantation.
Silibinin is considered the first-choice antidote for Death Angel mushroom poisoning. It works by inhibiting the uptake of amatoxins by liver cells and preventing the recycling of these toxins within the body. However, silibinin may not always be obtainable, and alternative treatments may be necessary.
N-acetylcysteine (NAC) is often used in combination with silibinin or as a standalone treatment. NAC protects the liver by scavenging oxygen-free radicals, reducing the impact of toxins on liver cells. NAC therapy has been associated with reduced mortality in amatoxin poisoning cases.
In severe cases of amatoxin poisoning, liver transplantation may be required to save a patient's life. Liver transplantation is considered when there is severe liver damage or failure, indicated by rising serum ALT levels and INR values. The procedure involves replacing the damaged liver with a donor liver, aiming to restore liver function and prevent further deterioration.
Additionally, supportive treatments are crucial in managing Death Angel mushroom poisoning. These include fluid and electrolyte replacement, anti-emetic therapy to reduce vomiting, and activated charcoal to absorb toxins in the gastrointestinal tract. Dialysis may also be employed to remove toxins from the blood if kidney function is impaired.

Angel mushrooms are often mistaken for edible fungi
Angel mushrooms, also known as Death Angels or Destroying Angels, are among the most toxic mushrooms in the world. They are often mistaken for edible fungi, which can be extremely dangerous. Angel mushrooms are characterised by their white gills and stalks, with caps that can be pure white, or white at the edge and yellowish, pinkish, or tan at the centre. They are often found in woodlands, fields, or lawns, and can grow in Europe, North America, and Australia.
The danger of Angel mushrooms lies in their potent toxins, which include amatoxins, phallotoxins, and virotoxins. These toxins are not destroyed by cooking and can cause severe vomiting, diarrhoea, abdominal pain, and liver and kidney failure if ingested. As little as half a mushroom cap can be fatal if not treated quickly. Unfortunately, symptoms of Angel mushroom poisoning may not appear for 5 to 24 hours, by which time the toxins may have already caused irreversible damage.
One reason Angel mushrooms are often mistaken for edible fungi is their resemblance to button mushrooms, meadow mushrooms, or horse mushrooms. Young Angel mushrooms that are still enclosed in their universal veils can also be mistaken for puffballs. However, slicing them in half longitudinally can reveal their internal mushroom structures, which differ from those of puffballs. Additionally, Angel mushrooms have a distinctive large, sac-like cup around the stalk's base, which can be hidden underground.
To avoid accidentally consuming Angel mushrooms, it is crucial to properly identify any wild mushrooms before consumption. Mushroom hunters recommend learning to recognise both Death Caps and Destroying Angels in all their forms before collecting any white-gilled mushrooms for consumption. Additionally, knowing the habitat of Angel mushrooms can help avoid accidental ingestion. They are often found in woodlands, fields, or lawns, especially near trees or shrubs.
While Angel mushrooms are deadly, there are treatments available for poisoning. Medical treatments include fluid and electrolyte replacement, oral activated charcoal, lactulose, IV penicillin, combined hemodialysis, and hemoperfusion. In some cases, a liver transplant may be necessary. Excessive hydration can also be helpful as soon as possible after ingestion.
