Scientists Uncover Evolutionary Past of Hallucinogenic 'Magic' Mushrooms

Scientists Uncover Evolutionary Past of Hallucinogenic 'Magic' Mushrooms

Catherine Griffin
First Posted: Aug 06, 2013 12:53 PM EDT

Hallucinogenic "magic" mushrooms are well known for their ability to affect those who eat them.  Yet researchers have long wondered exactly where these mushrooms fit in the fungal family tree. Now, scientists have uncovered the evolutionary past of this fungi, revealing a bit more about them and their potential use in medicinal applications.

Hallucinogenic mushrooms have been used for centuries in rituals, medicinally or just recreationally. In fact, ancient people in Central America used to actively ingest these mushrooms for the extrasensory perceptual effects it gave them in order to better assess the problems faced by their societies. That said, scientists officially discovered them in the 19th century. At that point, researchers delved into the mushrooms' taxonomy, biochemistry and historical usage. Now, scientists are learning a bit more about how they evolved.

In order to examine the mushrooms a bit more closely, the researchers employed new molecular and computational techniques. They produced the first multi-gene evaluation of the evolutionary development of Psilocybe, the genus of small mushrooms known for their hallucinogenic properties. This work is a major step when it comes to classifying and naming "magic" mushrooms.

So what did the scientists find? In the past, researchers found that the species of Psilocybe did not commonly descend from a single ancestor. Because of this, the hallucinogenic species were typically separated from their non-hallucinogenic relatives. This new study, though, places the two separate groups into different families: the Psilocybe (family Hymenogastraceae) and the Deconica (family Strophariaceae s.str).

It's likely that the mushrooms evolved independently instead of possessing a common ancestor. Another option is that they underwent several evolutionary losses, probably for ecological reasons. That said, the species of Psilocybe are united to some degree due to the fact that they possess the psychedelic compound psilocybin and other secondary metabolites, or products of metabolism.

The findings reveal a little bit more about how these mushrooms evolved and could tell scientists a little bit more about their properties. The work is important for understanding more about these mushrooms, which could aid current research concerning their medicinal uses.

The findings are published in the journal Botany.

I'm trying my best, quite occupied these past days but oh well, I'm glad you enjoy what I'm able to find and share :heart:

These warm words always give me this little push to continue :thumbup:

Much love :crazy:

So what exactly does this mean? That psilocybin is just a mutation that could potentially happen to any evolving species?

I've always theorized that psilocybes and amanitas are actually not far from each other on the evolutionary chart. My reasoning is that psilocin and amatoxins share a relatively similar indolic center. Psilocin is a 4-hydroxy-DMT, whereas amatoxins are a class of substances with a DMT or 5-hydroxy-DMT center, with a good number of other proteins and groups attached to it.

My thought is that in the psilocybes, a gene which is responsible for the binding of these other groups to a DMT-like intermediate to form the amatoxins is absent or turned off, and thus instead of the fungus forming the amatoxin, it instead forms the psilocin (and subsequently psilocybin).

In normal circumstances this may have been evolutionarily useless, but with mankind finding the usefulness in the effects of the psilocybes, they may have helped the genus to prosper. As to why this gene might have been turned off, one theory might be that since certain psilocybes (cubensis, mexicana) depend on cows to spread and prosper, if they did produce amatoxins which would likely be deadly to the cows themselves, they would be unable to prosper as well. Somewhere down the line, perhaps the mushrooms with the gene turned off were better able to prosper since they were less likely to kill their host. Psilocin/psilocybin in this case would have just been an accidental mutation, which again likely lasted thanks to mankind.

But that's all theory. :smile:

Awesome, convergent evolution of psychedelic effects.. I like this alot, though it's probably a by-product. pretty awesome

Can anyone find the actual study, as published by the journal, Botany? I searched for 'psilocybe' within that publication, but this study didn't come up.

Interesting idea. But I find it hard to believe that psilocyin did not originate as a poison to dissuade animals from eating the mushrooms.

On the other hand it's hard to explain why some mushrooms evolved deadly poisons while others went for non-deadly. If spreading spores as far as possible is the aim, then a poison that makes the animal quickly vomit or defecate (while it's still in a habitable area) would be effective but killing it would be less so.
