Many psychonauts are fond of exploring different strains because of their awareness of the varying potencies among shrooms. Among the Psilocybe cubensis species, Penis Envy stands out as a favourite among trippers for its potency. If you’re seeking potent effects in a different manner, Blue Meanies mushrooms offer an intriguing alternative worth exploring.

Key Takeaways:

  • Psilocybin and psilocin make up between 0.5 to 2.95 percent of the dry weight of this mushroom.
  • The Panaeolus cyanescens Blue Meanies are highly potent, which can be an alternative to tripping with Penis Envy.
  • Apply about 20% more when using dried mushrooms of Blue Meanies.

Why Trippers Enjoy Blue Meanies Mushrooms

Blue meanies, native to tropical and subtropical grasslands, thrive in dung-rich environments reminiscent of another well-known mushroom variety. Blue Meanies are reputed to contain a significantly higher concentration of psilocybin—approximately two to three times that found in cubensis.

Countries where Blue Meanies thrive:

  • South Africa
  • Madagascar 
  • Australia
  • the Caribbean
  • Puerto Rico 
  • Costa Rica
  • India
  • Malaysia
  • Indonesia
  • Thailand
  • Japan
  • Mexico
  • Bolivia
  • Brazil
  • Paraguay
  • Colombia
  • Venezuela
  • United States 

Identifying Blue Meanies is essential as various mushrooms are similar, which may lead to misidentification.

  • 1.5 – 4 cm across.
  • When young caps reach maturity, their light brown colour fades to off-white or light grey, occasionally exhibiting brownish or yellowish tones.
  • Starting out gray and turning black as the spores mature. 
  • Gills have a mottled appearance, and the edges are white.
  • Jet Black
  • 12 – 15 x 7 – 11 micrometer
  • Smooth, opaque, elliptical
  • 7 – 12 cm long
  • 2 to 3 mm thick
  • Equal to slightly enlarged at the base,
  • Coloured like the cap
  • Staining blue where bruised

The blue hue visible on the entire surface of these fruit bodies stems from the breakdown of psilocybin and psilocin, alongside other compounds present in the mushrooms. One theory suggests that this bluish colour might serve as a deterrent to potential predators. 

It’s necessary to distinguish between blueing and blackening. The latter, accompanied by an unpleasant odour, signals that your mushrooms may no longer be suitable for consumption.

The Name’s Origin

Panaeolus cyanescens is the species’ correct taxonomic name. “Panaeolus” originates from the Greek word for “all variegated,” which reflects the genus’ characteristic mottled or spotted texture and colouration. 

Some taxonomists still use the term “Copelandia cyanescens” to refer to the species before it acquired its current binomial name. This perpetuates confusion as it implies a shift to an entirely different genus, which is not the case.

Several theories exist regarding the origin of this name. Some suggest a connection to the “Blue Meanies” from the iconic Beatles film “The Yellow Submarine,” others propose its derivation from Australian slang used to describe magic mushrooms.


The effects of Blue Meanies can manifest swiftly due to their elevated psilocin levels compared to psilocybin. There are scant published data that corroborate assertions regarding the potency of these fungi. 

  • Erowid notes that these mushrooms contain a blend of psilocybin and psilocin ranging from 0.5 to 2.95 percent of their dry weight. 
  • In 1992, Stivje identified considerable variability in their potency, with psilocin levels ranging from 0.17 to 0.95 percent and psilocybin from 0.16 to 0.19 percent. 
  • Laussmann and Sigrid Meier-Giebing uncovered fascinating insights about the chemical composition of psilocybin and psilocin in a study involving 25 samples intercepted by German customs. These samples showcased an average psilocybin presence of 2.5% and a psilocin presence of 1.194%.

In comparison, Psilocybe cubensis possesses concentrations of psilocin between 0.14 to 0.42 percent and psilocybin between 0.37 to 1.30 percent.

Caution When Using Blue Meanies

Determining a precise dose for these mushrooms proves challenging due to the significant variation in potency between different harvests. Many sources recommend a fixed number of caps as a dosage, but this guidance has limitations. Not only do individual mushrooms vary widely in potency, but the inconsistency in cap sizes further complicates matters.

In broad terms, when using dried mushrooms, administer approximately 20% more than you would with Psilocybe cubensis. For instance, for a standard 3-gram dose equivalent of Psilocybe cubensis, around 3.6 grams of Panaeolus cyanescens would suffice.

Allow an hour or so to assess the effects. If you want to elevate your experience, you can consume an additional 1–5 caps and repeat the process. 

Other Tips:

  • Start with a modest dosage. Body weight, overall health, and individual tolerance significantly influence your reaction.
  • Being in a comfortable environment can help maintain composure during intense moments.
  • Enlist the presence of a trusted companion, someone who can maintain a clear-headed demeanour. Their support can be invaluable should your journey encounter rough patches.
  • Steer clear of combining mushrooms with alcohol or other substances. 
  • Prioritize hydration both before and throughout your mushroom excursion. Adequate hydration wards off nausea and aids in managing the effects more effectively.
  • Consume a light snack before a full meal to avoid nausea and vomiting.
  • Familiarize yourself with identifying features—a spore print can confirm that you’re dealing with authentic Blue Meanies rather than a hazardous look-alike.

Microdosing Blue Meanies

Microdosing shrooms is increasingly popular among trippers as a subtle yet impactful way to engage with these fungi. While microdosing doesn’t induce hallucinations or dramatic life-altering experiences, enthusiasts find value in its effects.

In a microdose, you might experience gentle euphoria, increased energy, and heightened clarity of vision without experiencing full hallucinations or impaired inhibition.

Many individuals, including those in creative professions and those managing conditions like ADHD or anxiety, find microdosing beneficial for mood enhancement, improved focus, and fostering creative thinking.

Determining the right microdose of Blue Meanies is subjective and depends on achieving desired effects without triggering a psychedelic experience. Individuals consume between 50 to 100 milligrams of psilocybin every few days.

Penis Envy Vs. Blue Meanies: Effects

Penis Envy and Blue Meanies distinguish themselves in various aspects, such as species, physical characteristics, and potency. Despite varying potency, seasoned enthusiasts favour both types for their strength. 

Distinguishing their effects proves challenging as they vary significantly depending on dosage and individual physiology. Exercise caution when dosing Blue Meanies, as some users mistakenly equate them with Psilocybe cubensis, which leads to an overly intense experience.


Blue Meanies contain high levels of tryptamine, which offers psychonauts a fascinating avenue for their next journey. Unlike the Psilocybe cubensis variant with lower psilocybin levels, careful dosing is paramount with this strain. Its potential to induce profound spiritual experiences, even in small doses, is noteworthy. For those seeking to expand beyond the familiar realms of Penis Envy, you might want to explore this strain.

Frequently Asked Section

How potent are the Psilocybe cubensis Blue Meanies?

Some sources indicate that Blue Meanies P. cubensis contains a psilocybin content ranging from 0.75% to 1% by weight. This places them within the general range observed in other Psilocybe cubensis strains.

Is it easy to grow Blue Meanies?

Cultivating Blue Meanies can be a bit more challenging than growing Psilocybe cubensis. While they thrive well in suitable outdoor climates, indoor cultivation requires a specific setup, patience, and meticulous care. 

They exhibit a slower growth rate and require twice the time to develop pins post-exposure to fruiting conditions. This extended cultivation period heightens the susceptibility to contamination. 

What happens if you eat a large quantity of shrooms?

Negative experiences can materialize in the form of unsettling hallucinations, heightened anxiety, paranoia, panic, or overwhelming fear. Individuals embarking on their first psychedelic journey, especially if they consume high doses or already grapple with anxiety or depression, might find themselves more vulnerable to encountering such distressing episodes. Unfamiliar or chaotic surroundings can also contribute to these negative experiences.

To mitigate the associated risks, users must consume psilocybin with a trusted individual in a comfortable setting and abstain from use when feeling emotionally distressed. 

Can tripping with potent mushrooms make me sleep faster?

Psilocybin influences serotonin levels, consequently impacting sleep patterns. Among individuals, responses to psilocybin can manifest differently. Some report experiencing restful, deep sleep; others may encounter insomnia or disrupted sleep. 

The dosage of psilocybin consumed, the environment, and the individual’s prior experiences with the substance all influence these responses. Recognize that the influence of psilocybin on sleep patterns may persist beyond the duration of the psychedelic experience.

Why do I have to know what Blue Meanies look like?

It is necessary to identify what Blue Meanies or other mushrooms look like to avoid consuming their toxic counterparts. Blue Meanies look similar to Protostropharia semiglobata, Conocybe, and Deconica species.
