Red and white mushrooms are some of the most iconic and recognisable fungi in the world. The most common variety is the Amanita muscaria, commonly known as the fly agaric or fly amanita, which is a white-gilled, white-spotted mushroom featuring a bright red cap. This variety is native to the Northern Hemisphere and is now also found in the Southern Hemisphere. Other varieties of red and white mushrooms include Amanita parcivolvata, which is found in eastern and southeastern North America, and Russula, which tends to have smooth dark red caps and white stems. While some red and white mushrooms are edible, many are toxic and should be avoided.

What You'll Learn
Amanita Muscaria
The name 'fly agaric' comes from the traditional practice of crumbling the mushroom into saucers of milk to attract and kill flies. The toxins in the mushroom make flies drowsy and cause them to collapse. The name 'muscaria' is derived from the Latin 'musca', meaning fly. The mushroom has also been used as an insecticide in England, Sweden, and Germany.

Toxicity and edibility
Red and white mushrooms do exist, with the Amanita muscaria, commonly known as the fly agaric or fly amanita, being one of the most recognisable fungi in the world. It is a large white-gilled, white-spotted mushroom with a bright red cap. It is native to the forests of the Northern Hemisphere but has now also been naturalised in the Southern Hemisphere.
Amanita muscaria is considered toxic due to its psychoactive and hallucinogenic properties, which can cause poisoning, especially in children and those seeking a hallucinogenic experience. However, fatal poisonings are extremely rare. The toxins in this mushroom can also be harmful to pets, causing a severe stomach upset and even death in some cases.
On the other hand, some sources argue that Amanita muscaria is edible and has been consumed throughout history, with proper detoxification methods. Boiling the mushroom, for example, reduces its toxicity by removing water-soluble ibotenic acid.
Another example of a red mushroom is Fistulina hepatica, commonly known as "ox tongue" or "beefsteak" due to its resemblance to meat. This mushroom is considered edible and is used as a meat substitute.
It is important to note that proper identification of mushrooms is crucial, as some poisonous mushrooms can be deadly. While Amanita muscaria is not usually fatal to humans, it can cause unpleasant side effects, and consuming any mushroom without proper knowledge of its toxicity and edibility is dangerous.

Hallucinogenic properties
Red and white mushrooms do exist, and they are among the most iconic types of mushrooms. The Amanita Muscaria, commonly known as the fly agaric or fly amanita, is a large, conspicuous, white-gilled, white-spotted mushroom with a bright red cap. It is one of the most recognisable fungi in the world.
Fly agaric is a hallucinogenic mushroom. It contains psychoactive chemicals that can induce hallucinations, including muscimol, ibotenic acid, muscarine, and bufotenine. Muscimol is a central nervous system depressant that may engage GABA receptors to deliver sedative-hypnotic, depressant, and hallucinogenic psychoactivity. It is considered the most potent psychoactive agent in fly agaric, and is ten times stronger than ibotenic acid. Ibotenic acid interacts with glutamate receptors, making it more stimulating and energizing. When mushrooms contain more ibotenic acid than muscimol, users typically report confusion, agitation, and euphoria. Muscarine exists in trace quantities (0.02% dry weight) and is the weakest psychoactive compound in this spotted species. Bufotenine is a weak hallucinogenic agent and poison, structurally capable of blocking the action of serotonin found in normal brain tissue.
The ingestion of fly agaric is one of the most common causes of mushroom poisoning, especially in children and those seeking its hallucinogenic effects. Poisoning symptoms include dizziness, confusion, paranoia, nausea, vomiting, diarrhoea, excessive salivation, perspiration, watering of the eyes, slowed and difficult breathing, dilated pupils, and excitability. However, fatal poisonings are extremely rare.
Fly agaric has been used medicinally for hundreds of years among tribal groups in Scandinavia, Eastern Europe, and Russia for its analgesic, anti-inflammatory, anxiolytic, and stimulant properties. Recent research on the mushroom's pharmacology supports these traditional uses, demonstrating that muscimol in fly agaric could have several medicinal benefits, including the potential for treating depression, insomnia, migraines, allergies, and gingivitis.

Real-life vs popular culture depictions
Red and white mushrooms do exist in real life, and they are among the most iconic types of mushrooms. They are typically characterised by their red caps and white warts or spots. These mushrooms are often toxic and can induce hallucinations if consumed. They are also called fly agaric or fly amanita, derived from their traditional use as an insecticide. The "fly" refers to the practice of crumbling the caps of these mushrooms into saucers of milk to attract and kill flies.
In popular culture, red and white mushrooms have been depicted in various ways, sometimes as symbols of good luck and enchantment, and other times as poisonous or hallucinogenic fungi. They are commonly associated with fairy tales, magical settings, and fantasy stories. For example, in the story of Alice in Wonderland, Alice is given fly agaric to eat, and it is speculated that the hallucinations caused by these mushrooms may have inspired the flying reindeer in Siberian folklore.
The distinctive appearance of red and white mushrooms has also made them popular in decorative arts and children's media. They are often featured in garden ornaments, paintings, and children's picture books, such as those depicting gnomes and fairies. The Super Mario video game franchise has also popularised the image of a red and white mushroom, although the in-game mushroom's effects differ significantly from those of its real-life counterpart.
While red and white mushrooms in real life can be toxic, some varieties of red mushrooms are edible and even provide unique health benefits. Examples of edible red mushrooms include Ox Tongue and Reishi, which can be consumed as supplements. However, it is crucial to properly identify mushroom species before consumption, as the line between poisonous and edible mushrooms can be thin, and some toxic varieties may resemble edible ones.
In summary, while red and white mushrooms do exist in real life and are often toxic, popular culture has depicted them in a variety of ways, sometimes emphasising their magical or hallucinogenic properties, while other times using their distinctive appearance for decorative or symbolic purposes. It is important to remember that consuming wild mushrooms without proper identification can be dangerous, and some mushrooms may be toxic even if they resemble edible varieties.

Identification and differentiation
Red and white mushrooms do exist, and they are among the most iconic types of mushrooms. However, it is important to note that not all red and white mushrooms are safe to consume. Some are highly poisonous and should be avoided. Proper identification is crucial before consuming any mushroom.
The most common type of red-capped wild mushroom with white spots is the Amanita muscaria, commonly known as the fly agaric or fly amanita. It is native to the Northern Hemisphere's temperate and boreal forests and is now also found in the Southern Hemisphere. It is easily identifiable by its prominent red cap with white flecks or warts and its large white-gilled, white-spotted mushroom shape. The cap is usually scarlet or orange, sometimes with white wart-like spots, and can grow to 20 cm across and 30 cm tall. The gills are white to cream and are located under the cap, closely packed and not joined to the stem. The stipe (stalk) is white, 5-20 cm high, and has a brittle texture. The base has a bulbous volva (cup-like base) with shaggy rings of scales, and there is generally no associated smell other than a mild earthiness.
The Amanita muscaria is considered toxic due to its hallucinogenic properties, containing psychoactive chemicals like muscimol, ibotenic acid, and muscarine. However, fatal poisonings are extremely rare. It is important to differentiate it from edible mushrooms like the Caesar's mushroom (Amanita caesarea), as they can look similar when the Amanita muscaria's white warty growths are washed away by rain.
Other red and white mushrooms include the blusher (Amanita rubescens), which has a similar shape to the fly agaric but with a pale, reddish-brown cap and cream spots. Some toxic red mushrooms from the genus Russula have smooth dark red caps and white stems.
While red and white mushrooms with caps and spots are the most iconic, there are other types of red and white mushrooms that do not conform to this stereotype. For example, the death cap is a pure white mushroom that is highly toxic and should be avoided.
When identifying red and white mushrooms, it is essential to look at various features beyond just the colour and shape of the cap. The size and shape of the entire mushroom, the texture of the cap (smooth or bumpy), the colour of the gills, and the flesh colour are all important identifying factors. These features help distinguish edible mushrooms from poisonous ones.
