What You'll Learn
Death Angel mushrooms are deadly poisonous fungi
Death Angel mushrooms, also known as Destroying Angel mushrooms in Europe, are deadly poisonous fungi. They are part of the Amanita genus, which includes over 900 species of mushrooms, nine of which produce amatoxins that are harmful to humans. Amatoxins are one of the most toxic mushroom poisons known, and as little as half a mushroom cap can be fatal if ingested.
Death Angel mushrooms are characterised by their white gills and stalks, with a ring on the stalk and a large, sac-like cup around the stalk's base. The cap is initially curved and may become flatter with a central swelling as the mushroom ages, and its colour can vary from white to yellowish-white, shades of ochre, and sometimes with a brownish centre. The gills are narrow to broad, closely spaced, and white. The stalk is white and pearly and may enlarge towards the base.
These mushrooms are commonly found in mixed woods and grass near trees, often in dappled sunlight with only a few hours of direct sunlight each day. They are particularly prevalent in the spring, when they first appear, and can be found in cleared fields or on lawns, wherever there is an adequate supply of buried organic matter.
Consuming Death Angel mushrooms can have severe health consequences and lead to death. The initial symptoms typically appear within 5 to 24 hours of ingestion and include gastrointestinal issues such as vomiting, diarrhoea, abdominal pain, and cramps. These symptoms may subside temporarily, creating a false sense of security, while the toxins continue to damage vital organs, primarily the liver and kidneys. If left untreated, the poisoning can progress to jaundice, delirium, seizures, and coma, ultimately resulting in death from liver or kidney failure.
It is crucial for mushroom hunters to be able to recognise and avoid Death Angel mushrooms due to their deadly nature. They can be mistaken for edible fungi, such as button, meadow, or horse mushrooms, especially when still enclosed in their universal veils, resembling puffballs. However, slicing them in half longitudinally can help distinguish them from puffballs.

They are part of the Amanita genus
Death Angel mushrooms, also known as Destroying Angels, are part of the Amanita genus. Amanita is a large family of mushrooms with over 900 species. Of these, nine species produce amatoxins that are harmful to humans. Other dangerous compounds found in these mushrooms are phallotoxins and virotoxins, all classified as cyclopeptides.
The name "Destroying Angel" applies to several similar, closely related species of deadly all-white mushrooms in the genus Amanita. They are Amanita virosa in Europe, Amanita bisporigera in eastern North America, and Amanita ocreata in western North America. Another European species, Amanita verna, also referred to as the "fool's mushroom," was first described in France in 1780.
Destroying angels can be mistaken for edible fungi such as the button mushroom, meadow mushroom, or horse mushroom. Young destroying angels that are still enclosed in their universal veils can be mistaken for puffballs, but slicing them in half longitudinally reveals internal mushroom structures. This is why it is recommended to slice in half all puffball-like mushrooms picked when mushroom hunting.
Amanita mushrooms are responsible for most deaths caused by mushroom poisoning. The toxin responsible for this is amatoxin, which inhibits RNA polymerase II and, in the case of Amanita phalloides, RNA polymerase III. Symptoms of ingestion do not appear for 5 to 24 hours, when the toxins may already be absorbed and the damage (destruction of liver and kidney tissues) is irreversible. As little as half a mushroom cap can be fatal if the victim is not treated quickly enough. The symptoms include vomiting, cramps, delirium, convulsions, and diarrhea.
It is crucial to know how to identify these poisonous mushrooms, especially when mushroom hunting or consuming foraged mushrooms.

Amatoxins are the primary toxin in Death Angel mushrooms
Death Angel mushrooms, also known as Destroying Angels in Europe, are highly toxic and dangerous. They are part of the Amanita genus, which includes over 900 species of mushrooms. Of these, nine species produce amatoxins, which are harmful to humans. Amatoxins are a type of cyclopeptide, consisting of at least eight compounds with a similar structure of eight amino-acid rings.
Death Angel mushrooms are characterised by their white, smooth caps, which may develop a tan centre with age. The stalk is also white and pearly, sometimes with a swollen base. The ring, or annulus, located at the top of the stalk, is white, large, and flaring. The stalk base has a white, cup-like sheath called the volva. These mushrooms have a white spore print. They resemble several edible species, increasing the risk of accidental poisoning.
The primary toxin in Death Angel mushrooms is amatoxin, which inhibits RNA polymerase II and, in some cases, RNA polymerase III. This inhibition disrupts the synthesis of messenger RNA (mRNA), microRNA, and small nuclear RNA. Amatoxins cause severe poisoning and organ damage, particularly to the liver and kidneys. Initial symptoms of ingestion include gastrointestinal issues such as abdominal pain, diarrhoea, and vomiting. These symptoms may subside temporarily, leading to a false sense of security, while the toxins continue to damage the organs. The second phase of poisoning may occur after a day or two, with symptoms such as jaundice, delirium, seizures, and coma. Death typically occurs 6 to 16 days after poisoning, with liver failure being the most common cause.
Treatment for Death Angel mushroom poisoning includes preliminary medical care, supportive measures, specific treatments, and, in severe cases, liver transplantation. Early treatment is crucial, as amatoxin poisoning can be irreversible. Intravenous penicillin G and intravenous silibinin have shown some effectiveness in treating amatoxin poisoning. However, there is currently no definitive antidote available.

They can be mistaken for edible mushrooms
Death Angel mushrooms, also known as Destroying Angel mushrooms, are highly toxic and have been responsible for mushroom poisonings, especially in western North America. They are part of the Amanita family, which includes several other deadly poisonous fungi, such as the death cap (A. phalloides).
The danger of Death Angel mushrooms lies in their resemblance to edible mushrooms. Young destroying angels, still enclosed in their universal veils, can be mistaken for puffballs. However, slicing them in half longitudinally reveals their internal mushroom structures, which is why it is recommended to cut puffball-like mushrooms in half before consumption.
Additionally, Death Angel mushrooms can resemble other edible fungi, such as the button mushroom, meadow mushroom, horse mushroom, and Agaricus arvensis and A. campestris. They may also be confused with the prized Amanita velosa, which grows in the same areas. This similarity in appearance poses a significant risk to those collecting mushrooms for consumption, especially if they are not adequately informed about the characteristics of poisonous species.
The Death Angel mushroom typically has a white, smooth cap, though the center may change color to tan or yellowish-white with age. It has a white stalk (stem) with a swollen base and a white ring at the top. The stalk base is characterized by a white, cup-like sheath called the volva. These mushrooms produce amatoxins, phallotoxins, and virotoxins, which are harmful to humans and can lead to severe poisoning and even death.
To avoid accidental consumption of Death Angel mushrooms, it is crucial to properly identify both the death cap and the destroying angel in all their forms before collecting any white-gilled mushrooms for consumption. Knowing how to recognize these deadly mushrooms is of utmost importance when foraging or consuming wild mushrooms.

Symptoms of poisoning can be treated in some cases
Death angel mushrooms, also known as destroying angels, are a group of highly toxic mushrooms in the Amanita genus. They are among the most toxic mushrooms in the world and are responsible for the majority of deaths due to mushroom poisoning. Amatoxins, phallotoxins, and virotoxins are the toxins present in death angel mushrooms that are harmful to humans. These mushrooms can be mistaken for edible fungi, such as the button mushroom, meadow mushroom, or horse mushroom, especially when they are still enclosed in their universal veils.
The second phase of poisoning occurs after a day or two, when more severe symptoms manifest due to toxin-mediated damage to vital organs. These symptoms include jaundice, delirium, seizures, convulsions, and coma. Treatment for poisoning with death angel mushrooms can be challenging, and hospitalization is often required. Preliminary medical care for poisoning includes gastric decontamination with activated carbon or gastric lavage. However, due to the delay between ingestion and the onset of symptoms, patients often arrive for treatment long after ingestion, reducing the efficacy of these interventions.
In cases of amatoxin poisoning, intravenous silibinin, an extract from the blessed milk thistle, may be beneficial in reducing the effects of the toxins by preventing their uptake by hepatocytes and protecting undamaged hepatic tissue. Liver transplants have become a well-established treatment option for amatoxin poisoning, but they come with significant complications and mortality risks. Evidence suggests that modern medical treatments have improved survival rates, but permanent liver damage may still occur in some cases.
