Panaeolus Cyanescens: The Psychedelic Blue Meanies Mushroom

Panaeolus cyanescens is a very potent hallucinogenic mushroom, and this results from it being a strong producer of psychoactive compounds – psilocybin and psilocin.  The psilocybin and psilocin levels are higher in Panaeolus cyanescens than in other ‘magic mushrooms,’ of which there may be over 100 different types. Magic mushrooms refer to a group of fungi that produce the psychoactive compound psilocybin. These mushrooms have been consumed for approximately 3000 years, originally dating back to Mexico, and are still used by natives in ceremonies, including religious ceremonies, and for healing purposes. Many that have consumed Panaeolus cyanescens have described having spiritual experiences.

For this reason, it is not unheard of for people to try to cultivate these mushrooms themselves, although with varying levels of success since Panaeolus cyanescens is sensitive to the correct levels of air, temperature, and humidity. They are particularly fond of nutrient-rich areas, especially where livestock graze, as they grow on dung. Panaeolus cyanescens has a variety of names that can be used interchangeably including Copelandia Cyanescens, Blue Meanies, and Pan Cyans.

Panaeolus Cyanescens Look-Alikes

Pholiotina rugosa looks like Panaeolus cyanescens, but it is essential that the difference is identified since it contains amatoxins that are deadly. The difference is that the spores of Pholiotina rugosa are a rusty orange to brown in comparison to the dark purple or black spores of Panaeolus cyanescens.

Tubaria furfuracea is similar to Panaeolus cyanescens, but it is not poisonous; although it is hygrophanous like Panaeolus cyanescens, it grows in woodchips and not dung; they are also more delicate and not as bendy as Panaeolus cyanescens; they also have a spore print that is light orange or brown.

Galerina marginata is another look-a-like that is deadly if eaten, it has a rusty orange spore print and will usually be found growing on decaying wood; it also bruises black rather than blue-green like Panaeolus cyanescens on its stem.

The last look-alike is Panaeolus Antillarum. They are macroscopically similar mushrooms that were once thought to be the same. Panaeolus cyanescens is hallocinogenic where P.Antillarum is not. P. Antillarum has a thicker cap and is also lighter in color.

Not a look-alike, but a strain of Psilocybe cubensis also goes by the name “Blue Meanie” and while they won’t be confused in appearance they are sometimes written about under the Blue Meanie name in literature. I personally differentiate the two in literature by referring to the Psilocybe version as Blue Meanie Cubensis.

Panaeolus Cyanescens Benefits

Panaeolus cyanescens produces serotonin and tryptophan in addition to the psychoactive compounds. Tryptophan is an essential amino acid, meaning it needs to come from dietary sources, and serotonin is a neurotransmitter produced in the brain. Some scientists consider psilocybin to produce ‘madness’ or schizophrenia-like conditions, whilst others were interested in the creative effects and alterations to cognitive behaviors and spiritual or mystical experiences this substance gave people. Psilocybin, a tryptamine derivative and the most important ‘toxic’ component of these mushrooms, enhances serotonin levels in the central nervous system (CNS) [1.]. Serotonin has a few important roles, including that of a neurotransmitter, and here it can help promote feelings of happiness and general mental well-being. Sometimes people with low levels of serotonin suffer from mood disorders such as depression or a general feeling of being down. In this regard, psilocybin found in Panaeolus cyanescens has been explored as a potential therapeutic for depression, anxiety, and mood disorders. There has been some promising data produced with one study showing that all 19 participants had reduced depressive symptoms, one week after treatment with psilocybin, and 47% met the criteria response, five weeks post-treatment [2.]. This continues to be an exciting area of research with psychoactive substances being explored for use in psychiatry.

Panaeolus Cyanescens Toxicity, Safety & Side Effects

There is a lot of controversy around whether Panaeolus cyanescens is considered toxic or not. Regardless, it will cause hallucinations. Always seek medical advice before self-administering for medicinal purposes and if pregnant or breastfeeding. Due to the number of deadly similar-looking fungi, it is advisable to seek advice from a professional mycologist.

My name is Austin Collins.

I've dedicated my life to Mushrooms.

I believe Mushrooms are the best kept secret when it comes to health and well being.

For that reason, I would like to share a company with you that in my opinion makes the best mushroom products on the market. 

The company is called Noomadic Herbals, my favorite supplement they make is called "Mushroom Total".

I take their products every day and they have helped me think better and have more energy. Give them a try.

  1. in case that someone would like to ingest these, is making tea the best option? does boiling the mushroom get rid of the beneficial compounds found in the fruit? thank you 🙂

    • Tea is much more pleasant Tom. Mushrooms tend to have a bitter farmy taste isn’t very pleasant. Diluting in water will only make the effects happen quicker.

  2. You took the typed words out of my fingers – however, as I’m typing… I have come across one curious thought..,I wonder why the mica cap (Coprinellus micace) was not included in the look alike list. When mica is young, I’ve seen it meet most of the description of Pan Cyan. One exception would be the striations that run from the margin to damn near (if not all the way) to the center of the cap. Although, when young and small mica does not necessarily feature the striations… or they’re very faint in my experience. Now, the caps of mica will turn into ink within several hours… slower to auto-digest,,,and much less ink on the mica as opposed to its sibling Coprinopsis atramentaria.

  3. I am a cancer patient who just found mushrooms again. I have alot of questions but 1 important one is… what does it mean when they say you have have to grow it outside first. HOW!? First I’m hearing this ty all so much

  4. Where can you get spores?
    Are there other “magic “ mushrooms that have the word blue in the common name? (I’m trying to remember something that was recommended to me and all I remember is the word blue)
