What Is Amanita Mushroom?

Amanita mushroom is a toxic fungi that belongs to the genus known as Amanita. It is widely known due to its potential lethality when eaten.

The term “amanita” can refer to more than 500 species. Of these, about 600 are edible, and 50 have psychoactive compounds that can cause hallucinations when ingested.

Some common Amanita varieties include Amanita muscaria or the Fly Agaric, the Panther Amanita or A. pantherina, and the Deadly Amantia or Amanita virosa.

Typically, Amanita mushrooms have white or cream-colored spore prints and produce a sac-like cup at the base that is called the volva.

Some of the tips on identifying Amanita varieties include inspecting the color, shape, and texture of the cap, stem, and surrounding volva.

It is important to remember that consuming any wild mushrooms, including Amanita mushrooms, can be inherently dangerous. Thus, expert identification and knowledge are important factors in determining the safety of any wild mushroom before consumption.

Amanita Varieties

The following sections discuss the characteristics and varieties of the Amanita mushrooms.

Amanita Muscaria

Amanita muscaria is generally found in Europe and North America but can also grow throughout Asia and the Southern Hemisphere. It can be mystifying due to its vibrant reddish or orange colors.

It has a medium-sized cap and white to yellowish warts or scales on a medium-length white stem. It is widely referred to as Fly Agaric or Fly Amanita because it has insecticidal properties and can be used to kill flies when crushed and mixed in milk.

Amanita Caesarea

This variety goes by many names, including Caesar's Mushroom, King Agaric, or the Royal Fly Agaric. It is edible and is a favorite among mushroom hunters, gardeners, and cooks.

Amanita caesarea was once limited to the Mediterranean climate zone, specifically Southern Europe and North Africa. It sports a reddish or orange cap, white stem, and pale yellow or gold gills.

Amanita Pantherina

Panther Amanita is also frequently mistaken for Amanita muscaria because of its striking red to orange cap and white, yellowish warts. The distinction can be that the Panther Amanita's edges curl inward and take on a tissue-like texture.

It also has white to pale-yellow gills and a stem that can reach up to five inches tall. The stem's base may taste sweet, earthy, or somewhat bitter.

Dangerous Amanita Variants

Some Amanita mushrooms are highly toxic and are best always avoided. The most toxic Amanita species include:

Amanita Bisporigera

Amanita bisporigera or the Destroying Angel can be found in North America. It has a white or yellow cap and white gills.

It does not produce warts but emits a strong smell, which has been described as sweet or sickening. Its stem is smooth, white, and roughly the same width as its cap.

Destroying angels are particularly toxic but can be found growing in similar habitats to the death cap.

This can put foragers at risk if they are not knowledgeable about the key identifying features that distinguish the two – such as the cap and stem. The bell-shaped veil can persist when they are young, then forms a skirt at maturity.

Amanita Ocreata

Commonly known as the Western North American destroying angel or California Destroying Angel survives on plant matter and produces toxins that damage liver cells.

They have a smooth white cap, white gills, and a white stem without any vegetation. It still has a destructive effect if consumed in large amounts since the typical heat from cooking does not destroy its poison.

Amanita ocreata, also known as the death cup, does not develop warts or scales on its cap. Instead, it has a smooth, plain white surface.

Amanita Virosa

Amanita virosa is known as the Destroying Angel, like Amanita bisporigera. This species can be found all around Europe and parts of North America.

Its cap ranges in a pale yellowish-white with gills and stem color similar to the other Destroying Angles. Its ring and sack-like volva around the base of the stem can be easily removed.

Amanita Gemmata

Amanita gemmata is called the Gemmed Amanita. Its cap is yellow and warty when young, and white when mature. The stem is white, and the circular ring around the middle of the stem can be pulled off.

Amanita Mushroom Poisoning

Amanita mushroom contains amatoxins, a group of cyclopeptides that damages the DNA, RNA, and various proteins inside cells. Amanitins have eight single letter amino acids and immune cells inside the liver absorb them.

Aside from the gastrointestinal (GI) symptoms from the Orellanine present in the mushroom, the Amanita toxins can induce liver damage and potentially fatal hepatitis.

Death has been reported within several days of ingestion when a treatment has not been provided.

The symptoms of Amanita mushroom include:

  • Nausea and vomiting
  • Diarrhea
  • Stomach pain and cramping
  • Bloody stool
  • Dark urine
  • Jaundice
  • Weakness and fatigue

It takes around six to twenty hours after ingesting an Amanita mushroom before the symptoms begin. There is no specific antidote for Amanita poisoning but supportive care can be given to alleviate its symptoms.

A Memorable Encounter: The Deadly Destroying Angel

I still remember the day vividly when I came across a deadly destroying angel mushroom during one of my hikes in the Pacific Northwest. It was a sunny afternoon, and I was exploring a dense forest with my friend, Sarah. As we walked along the trail, our eyes were drawn to a cluster of pristine white mushrooms with delicate caps and slender stems.

Curiosity got the best of us, and we decided to investigate further. We knelt down to get a closer look, and I couldn't help but marvel at the mushroom's beauty. Little did I know that I was face to face with one of the most poisonous mushrooms in the world.

Unbeknownst to us, the deadly destroying angel, scientifically known as Amanita virosa, stood innocently among the forest floor. Its alluring appearance masked the deadly toxins within, making it a silent killer. Sarah, being an amateur mycologist, recognized the mushroom and immediately urged me to back away. She cautioned me about its lethal nature and the potential dangers it posed.

As we continued our hike, Sarah explained that consuming just a small portion of the deadly destroying angel could lead to severe organ failure and even death. She recounted a case study she had come across where a family mistakenly added it to their stir-fry, thinking it was an edible variety. Tragically, they suffered from acute liver failure, and although medical intervention saved their lives, the incident left a lasting impact on them.

This encounter with the deadly destroying angel served as a stark reminder of the importance of proper knowledge and caution when it comes to foraging for mushrooms. It highlighted the need to educate ourselves about the different varieties, their distinguishing features, and the potential dangers they may pose. While the world of amanita mushrooms is vast and fascinating, it is crucial to approach it with respect and awareness to ensure our safety and well-being.

Final Thoughts

Amanita mushrooms are a diverse group of mushrooms that encompass both edible and toxic varieties. It is essential to identify this fungi correctly to avoid dangerous results.

Among the most well-known species in this genus are the Fly Agaric or Amanita muscaria, the Panther Amanita or Amanita pantherina., the Caesar's Amanita or Amanita caesarea.

Apart from these three, more dangerous Amanita mushrooms exist. This includes the Destroying Angel (Amanita bisporigera), the Death Cap (Amanita phalloides), the Gemmed Amanita (Amanita gemmata), among others.

Amanita poisoning can lead to serious, potentially life-threatening health consequences due to the presence of amatoxins and Orellanine.

The symptoms result in liver damage, kidney failure, and even death, which is why it is important to seek treatment immediately.

It is best to avoid ingesting wild mushrooms of any kind unless a trained expert has verified the species and deemed it safe for consumption.
