South Africa is well known for its rich biodiversity and remarkable variety of flora, including a wide assortment of native and exotic mushroom species. While many of these mushrooms are harmless and even edible, there are several toxic mushrooms that pose serious health risks to humans and animals. This article will take a look at some of the most dangerous mushrooms found in South Africa and the various effects they can have on those who consume or come into contact with them.

The Amanita Phalloides: The Death Cap

The Amanita phalloides, or death cap, is considered one of the most poisonous mushrooms in the world. Responsible for a significant number of fatalities worldwide, the death cap contains potent toxins known as amatoxins. These toxins cause severe damage to the liver and kidneys, leading to organ failure and, if left untreated, death. Symptoms of death cap poisoning include vomiting, diarrhea, abdominal pain, and dehydration, and may not appear for several hours after ingestion.

Psilocybe: The Magic Mushroom

Psilocybe mushrooms, also known as magic mushrooms, are infamous for their hallucinogenic properties. While not as deadly as the death cap, magic mushrooms still pose a significant danger to humans when consumed. The active compounds in these mushrooms, psilocybin and psilocin, cause altered perceptions, hallucinations, and even psychosis in severe cases. Long-term effects of magic mushroom consumption can include persistent hallucinogen perception disorder (HPPD), flashbacks, and an increased risk of developing a mental illness.

Cortinarius: The Deadly Webcap

The Cortinarius genus of mushrooms is notorious for its several highly toxic species. The deadly webcaps contain a group of toxins known as orellanine, which cause severe kidney failure in those who consume them. Symptoms of Cortinarius poisoning are similar to those of Amanita phalloides and may include nausea, vomiting, abdominal pain, and dehydration. What makes Cortinarius poisoning particularly dangerous is the delayed onset of symptoms, which can occur anywhere from 2 days to 3 weeks after ingestion.

Galerina: The Deadly Galerina

Galerina mushrooms, sometimes referred to as deadly galerinas, are another toxic group of mushrooms found in South Africa. Like the death cap, galerinas contain amatoxins and cause severe damage to the liver and kidneys. Symptoms of galerina poisoning are almost identical to those of Amanita phalloides poisoning and may not appear for several hours after ingestion.


Mushroom foraging can be an enjoyable and rewarding activity, but it is essential to exercise caution when venturing into the wild to collect these fascinating organisms. The consequences of mistakenly consuming one of the toxic mushrooms mentioned above can be severe and even deadly. It is crucial to have a thorough understanding of the mushrooms found in your region and to seek expert guidance if you are unsure about the safety of a particular species.
