When we think of mushrooms, the first image that often comes to mind is a cute little red cap covered in white dots. Amanita muscaria is the classic mushroom found in children's books and is likely the most photographed mushroom in the world. But did you know it can be dangerous?

This mushroom’s colloquial name, fly agaric, probably derives from its traditional use as a fly killer. It has also been used throughout history in religious rites for its hallucinogenic properties. However, the presence of several toxins can produce other effects as well, including nausea, vomiting, and diarrhea. Although it is not the most poisonous of all mushrooms, it’s best not to be seduced by its charming appearance—stay away from it.

Cortinarius orellanus is a medium-sized mushroom with a cylindrical yellowish stem, an orange-brown cap, saffron-colored gills, and yellowish flesh. Commonly known as the fool’s webcap, it is native to Europe and is typically found in mountain forests. It prefers moist, organic-rich soils and is most prevalent during the summer and fall months.

The fool’s webcap is one of the most poisonous mushrooms known to exist. It contains orellanin, a nephrotoxic compound that can cause severe kidney damage in humans. Symptoms of poisoning—including lower back pain, nausea, vomiting, and diarrhea—can take several days to appear, making diagnosis and treatment especially difficult.

This species is considered one of the few toxic members of the Boletus genus. In the areas where it grows—warmer regions of Europe—it is feared for its poisonous effects, which appear shortly after ingestion. Although caution is warranted, it is not a deadly mushroom; however, it can cause dehydration, diarrhea, nausea, and severe abdominal pain.

Despite bearing some resemblance to edible mushrooms, its size often gives it away. Satan’s bolete can reach up to 20 inches in width, and it is not uncommon to find specimens weighing around 4.5 pounds. Its cap is beige, it has a bulbous red stem, its flesh is light yellow and turns blue when cut, and it emits a notably unpleasant odor.

Psilocybe semilanceata, commonly known as the liberty cap, is a mushroom known for its psychotropic effects. It grows mainly in humid and temperate areas of the Northern Hemisphere, particularly in Europe. It has a distinctive nipple-shaped cap, and its color ranges from whitish when young to brown as it matures. The mushroom has a bitter taste.

Although the liberty cap is considered to have low toxicity, its ingestion can produce a range of effects, including altered perception of space and time. It may also cause temporary paranoia, with effects typically lasting between 3 and 6 hours. For this reason, its consumption is not recommended outside of a controlled environment.

Eating even a single piece of Amanita virosa can cause irreversible liver damage, and you should be especially careful because it can be easily mistaken for edible white-capped species.

In the eastern United States, the destroying angel appears from early summer to early autumn. It has a white cap that is initially ovoid and later flattens with age. The stalk is slender and covered with fine hairs, and it features a membranous ring. Despite its pleasant smell and reportedly good taste, this mushroom is extremely poisonous—ingesting it can result in death.

The false morel can be found in spring in coniferous forests. Its cap is brain-like, with intricate wrinkles and folds, and its color ranges from light brown to reddish brown depending on humidity.

Despite its scientific name—Gyromitra esculenta ("esculenta" meaning "edible")—the false morel is highly toxic unless properly prepared. In some individuals, it can be dangerous even after cooking; its toxins are volatile, and poisoning can occur by inhaling the fumes released during boiling. Nevertheless, the false morel remains a popular mushroom in some European countries, such as Finland, where it is used in certain traditional dishes. Would you dare to try it?

Lepiota brunneoincarnata may be tiny in size, but it is unquestionably deadly. It’s important to be able to recognize this mushroom and exercise caution when encountering it in the wild. The good news is that its appearance differs significantly from most edible species, making it less likely to be confused with them.

Commonly known as the deadly dapperling, this mushroom is found throughout Europe and parts of Asia. It typically appears during the summer and autumn months in meadows, parks, gardens, shrublands, and along roadsides. It contains a toxin called amatoxin, which is absorbed through the digestive tract and can cause symptoms such as abdominal pain, gastroenteritis, diarrhea, and vomiting. If not treated promptly, it can lead to death within a week.

Galerina marginata, known colloquially as autumn skullcap, is found in coniferous forests across North America, Europe, Asia, Japan, and Australia. Although it can appear at various times of the year, it is most commonly found in autumn. It has a soft brownish color, and its cap surface is often slimy with a greasy appearance.

Like the deadly dapperling, the autumn skullcap contains amatoxins, which interfere with essential cellular functions. The first symptoms of poisoning appear 6 to 24 hours after ingestion. It can cause renal failure and eventually death if not treated within the first four days.

Entoloma sinuatum is responsible for numerous cases of poisoning, as it can be mistaken for several edible species. At first glance, the body of the livid pinkgill looks like a classic field mushroom—its cap often displays a creamy light gray color. It typically grows in clay and limestone-rich soils, especially in beech and oak forests across Europe and parts of North America.

Although it does not have an unpleasant taste, you shouldn’t eat it. It can cause severe gastrointestinal disorders, including persistent diarrhea and vomiting, which may last for several days, and in some cases, up to two weeks.

The death cap (Amanita phalloides) accounts for the vast majority of mushroom poisoning deaths worldwide—hence its name. Consuming less than 2 ounces of this mushroom is enough to be fatal; an even smaller dose can kill a child and cause severe poisoning in adults.

Native to the United Kingdom and parts of Ireland, the death cap has rapidly spread over the past century to Australia and North America. It can grow up to 6 inches tall and has a domed cap sometimes tinged yellow or green, along with a white stem, which makes it difficult to distinguish from some edible mushrooms. Even its spores are poisonous. Therefore, if you have handled a death cap, avoid touching your mouth and always wash your hands thoroughly before eating.

Why do we say ‘kick the bucket’? Discover 12 idioms with morbid origins

We use a lot of strange phrases without thinking twice, but some have surprisingly grim origins. Ever say someone "kicked the bucket" or "bit the dust"? These everyday expressions sound harmless, but have more somber roots. Take a look at 12 of these idioms. Do you use any of these?

In 13th-century Britain, bakers risked losing a hand if they sold underweight bread, according to the Assize of Bread and Ale under Henry III. To avoid punishment, they often added a little extra to each order.

When selling 12 loaves, bakers would include a 13th—called a "vantage" loaf. This became what is now known as "a baker’s dozen."

Saying you're "as pleased as punch" sounds cheerful, but it has dark roots. The phrase comes from Punch from the Punch and Judy puppet shows, who gleefully committed violent acts.

Popular in 17th-century England, these shows featured Punch killing his family and others with a slapstick, laughing after each act.

The phrase "meet a deadline" might sound stressful today, but its origins are far darker. During the Civil War, the "deadline" referred to a boundary at Andersonville Prison, where Union soldiers were held.

This line, 20 feet inside the outer wall, was meant to prevent escapes. Any prisoner who crossed it was shot by guards in pigeon roosts. The term came from this deadly boundary, where crossing meant certain death.

Today, a "blockbuster" refers to a huge commercial hit, but the term originally described powerful bombs from World War II.

The British Royal Air Force used blockbusters, massive cylinders filled with explosives, capable of destroying entire streets. It wasn’t until 1957, nearly a decade after the war, that the term shifted to describe big entertainment successes.

The phrase "to bulldoze" someone means to force or bully them, but its origins are much harsher. First used in 1876, "bull dose" referred to brutally whipping or beating someone, similar to how a bull might be punished.

By 1880, "bulldoze" became a verb, and eventually, the heavy machinery designed to push through obstacles was named a bulldozer.

The word "sinister" comes from the Latin sinister, meaning "left" or "on the left side." By the 15th century, left-handedness was associated with evil, often linked to witches and the devil.

Because of this stigma, left-handed people were forced to use their right hands. Today, however, we know that being left-handed doesn’t make anyone sinister, and many renowned thinkers, like Leonardo da Vinci and Benjamin Franklin, were left-handed.

The Mad Hatter from Alice’s Adventures in Wonderland is famous for his colorful personality, but his madness has historical roots. In the 18th and 19th centuries, hat-makers, known as "hatters," often suffered from mercury poisoning due to their work with the chemical.

This poisoning led to mental deterioration, giving rise to the idea of the "mad" hatter, a term that Carroll cleverly incorporated into his character.

Today, "pulling your leg" means joking or fooling around, but it once had a much darker meaning: in 19th-century London, thieves would pull people’s legs to drag them down before stealing their belongings.

This tactic was commonly used by robbers, turning what is now a lighthearted phrase into a serious crime.

In the world of films, we often see characters drinking whiskey before a quick surgery or amputation. But in real battlefields, soldiers didn’t have that option.

One theory about the origin of the expression "to bite the bullet" suggests that, during painful medical procedures, wounded soldiers would literally bite down on a bullet—taken from the ground or from their own weapon—to help endure the agony without crying out.

The phrase "God bless you" after a sneeze has several theories behind it. One theory links it to preventing the plague, while another suggests it’s a way of ensuring the soul stays in the body during a sneeze.

The phrase "kick the bucket" means to die and has been used since the 18th century. One theory connects it to the Catholic tradition of placing a bucket of holy water by the feet of the deceased for mourners to sprinkle.

Another theory suggests the term comes from 16th-century England, where "bucket" referred to a beam. When animals were hanged for slaughter, they would kick the beam as they died, giving rise to the idiom.

The phrase "bite the dust" likely originated in the 19th-century Old West, referring to gunfights and battles. It paints a vivid picture of someone falling to the ground and biting the dust after being struck by a fatal wound.

Over time, the expression broadened, and now it simply signifies someone’s death or defeat, no longer tied specifically to gunfights.
