Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are a polyphyletic informal group of fungi that contain psilocybin, which turns into psilocin upon ingestion. Biological genera containing psilocybin mushrooms include Psilocybe, Panaeolus (including Copelandia), Inocybe, Pluteus, Gymnopilus, and Pholiotina.

Amongst other cultural applications, psilocybin mushrooms are used as recreational drugs. They may be depicted in Stone Age rock art in Africa and Europe, but are more certainly represented in pre-Columbian sculptures and glyphs seen throughout the Americas.

Psilocybin Mushrooms History

Psilocybin mushrooms have been and continue to be used in Mexican and Central American cultures in religious, divinatory, or spiritual contexts.

What Are Shrooms (Magic Mushrooms)?

Shrooms, also known as magic mushrooms, are wild or cultivated mushrooms that contain psilocybin, a naturally occurring psychoactive and hallucinogenic compound. Some research suggests this substance may help relieve symptoms of some mental health conditions. However, shrooms are illegal in most places and carry risks that people should recognize.

Psilocybin is considered one of the most well-known psychedelics, according to the Substance Abuse and Mental Health Services Administration (SAMHSA).1 Psilocybin is classified as a Schedule I drug, meaning that it has a high potential for misuse and has no currently accepted medical use in treatment in the United States.

What to Know About Mushrooms

Although certain cultures have been known to use the hallucinogenic properties of some mushrooms for centuries, psilocybin was first isolated in 1958 by Dr. Albert Hofmann, who also discovered lysergic acid diethylamide (LSD).

Magic mushrooms are often prepared by drying and are eaten by being mixed into food or drinks. Although, some people eat freshly picked psilocybe mushrooms.

Also Known As: Magic mushrooms are also known as shrooms, mushies, blue meanies, golden tops, liberty caps, philosopher’s stones, liberties, amani, and agaric.

Drug Class: Psilocybin is classified as a hallucinogen.

Common Side Effects: Shrooms are known to cause unwanted side effects such as nausea, yawning, feeling drowsy, nervousness, paranoia, panic, hallucinations, and psychosis.

How to Recognize Mushrooms

Psilocybin mushrooms look like dried ordinary mushrooms with long, slender stems that are whitish-gray and dark brown caps that are light brown or white in the center. Dried mushrooms are a rusty brown color with isolated areas of off-white.

Shrooms can be eaten, mixed with food, or brewed like tea for drinking. They can also be mixed with cannabis or tobacco and smoked. Liquid psilocybin is also available, which is the naturally occurring psychedelic drug found in liberty caps. The liquid is clear brown and comes in a small vial.
