What Are Entheogen Mushrooms? Meaning, Origin & Species

An entheogen is a psychoactive substance used in a spiritual, religious, or ceremonial context. The word was coined in 1979 by a group of scholars — Carl Ruck, Jeremy Bigwood, Danny Staples, Jonathan Ott, and R. Gordon Wasson — from the Greek éntheos (“full of the god, inspired”) and genésthai (“to come into being”), roughly meaning “generating the divine within.” Entheogen mushrooms are the fungi used this way, chiefly Psilocybe species and Amanita muscaria.

It’s a precise word for a specific idea, and it exists because the alternatives weren’t working. Here’s where it came from, how it differs from “psychedelic” and “hallucinogen,” and which mushrooms carry the label.

Where the Word Came From

By the late 1970s, researchers studying traditional ceremonial plant and fungal use had a vocabulary problem. The two available terms both carried baggage that got in the way of the work.

“Hallucinogen” implied that the experiences were simply false perceptions — hallucinations — which misrepresented how these substances were understood and used in the traditions being studied. “Psychedelic,” coined in 1956 from Greek roots meaning “mind-manifesting,” was more neutral in origin but had by then become inseparable from 1960s Western counterculture. Neither word could describe a Mazatec healing ceremony without dragging in associations that had nothing to do with it.

So in 1979, the group proposed entheogen: a term built specifically to describe substances used to occasion a sacred or spiritual experience within a ritual context. The point was framing. An entheogen isn’t defined by its chemistry — it’s defined by the setting and intention surrounding its use.

Entheogen vs. Psychedelic vs. Hallucinogen

These three words often get used interchangeably, but they aren’t synonyms. Each frames the same substances differently:

The practical upshot: the same mushroom can be described by all three words depending on what you’re emphasizing. Entheogen is the one that points at ritual use.

Which Mushrooms Are Considered Entheogens?

Two groups dominate, and they’re chemically unrelated to each other.

Psilocybe species are the largest group — more than 200 species produce psilocybin, including Psilocybe cubensis, P. mexicana, P. semilanceata (the liberty cap), and P. azurescens. These are the mushrooms most often meant by the phrase “entheogen mushrooms,” and they have the deepest documented ceremonial history in Mesoamerica. Explore the range in our guide to types of magic mushrooms.

Amanita muscaria — the red-and-white fly agaric — belongs in the category for entirely different reasons. It contains muscimol and ibotenic acid rather than psilocybin, and its ceremonial associations trace to Siberian shamanic traditions. R. Gordon Wasson, one of the scholars who coined the term, famously argued it was the mysterious Soma of the ancient Rigveda. See our Amanita muscaria guide.

The term extends well beyond fungi, too — peyote, ayahuasca, and iboga are all commonly described as entheogens within their own traditions.

Ceremonial Use and the Mazatec Tradition

The single most influential thread in how the West came to know entheogen mushrooms runs through Oaxaca, Mexico.

Psilocybe mushrooms had been used ceremonially in Mesoamerica for centuries — the Aztecs called them teonanácatl, often rendered as “flesh of the gods.” That practice survived into the twentieth century among the Mazatec people, where healers conducted all-night ceremonies called veladas.

In 1955 the Mazatec curandera María Sabina permitted Wasson to attend a velada, and his 1957 account in Life magazine introduced these traditions to a mass Western audience — with consequences for her community that were far from entirely welcome. We cover that story in depth in María Sabina and the Mazatec mushroom tradition.

That history is precisely why the word was proposed. The scholars who coined it were trying to describe what they had witnessed without flattening it into either clinical pathology or countercultural shorthand.

The Term Today

Entheogen remains most at home in academic, ethnobotanical, and religious-studies writing, where the distinction it draws still does real work. It also appears in contemporary discussions of psychedelic-assisted therapy and in the names of advocacy organizations built around ceremonial and religious use.

For researchers and collectors, it’s a useful piece of vocabulary: it signals that a mushroom is being considered through the lens of its cultural and ritual history rather than purely as a specimen. Both framings are valid — and knowing which one a source is using tells you a lot about what you’re reading.

Frequently Asked Questions

What does entheogen mean?

Entheogen means a psychoactive substance used in a spiritual, religious, or ceremonial context. It comes from Greek roots meaning roughly “generating the divine within,” and was coined in 1979 as a more respectful alternative to “hallucinogen.”

Who coined the term entheogen?

It was proposed in 1979 by a group of scholars including Carl Ruck, Jeremy Bigwood, Danny Staples, Jonathan Ott, and R. Gordon Wasson, who wanted a term that described ceremonial use without the baggage carried by existing words.

What is the difference between an entheogen and a psychedelic?

They often describe the same substances but emphasize different things. Psychedelic means mind-manifesting and is strongly associated with 1960s Western culture; entheogen specifically frames a substance by its sacred or ceremonial use.

Which mushrooms are entheogens?

Chiefly Psilocybe species — including P. cubensis, P. mexicana, P. semilanceata, and P. azurescens — along with Amanita muscaria, which belongs to the category through Siberian shamanic tradition rather than shared chemistry.

Is Amanita muscaria an entheogen?

Yes, though it works differently from psilocybin mushrooms. It contains muscimol and ibotenic acid rather than psilocybin, and its ceremonial associations come primarily from Siberian shamanic practice.

Are entheogens the same as magic mushrooms?

Not exactly. Magic mushrooms refers to psilocybin-containing fungi, while entheogen is a broader term covering any substance used ceremonially — including plants like peyote and ayahuasca, and fungi such as Amanita muscaria that contain no psilocybin at all.
