syn. Copelandia cyanescens, Hawaiin Blue Meanie, Blue Meanie cubensis, Goliath, Pan Cyan

Panaeolus cyanescens “Blue Meanies”, also called “Goliath”, “Pan Cyan mushroom”, or the “blue Hawaiian mushrooms”, is a long stemmed subtropical magic mushroom that grows from dung in pastures and fields.

To this day there are only thirteen Panaeoli known to be psilocybin-producing, most are found in the tropics and neo-tropics of both hemispheres.

The Blue Meanie cubensis, inherits all its names from its readily bluish bruising flesh (sign of psilocybin presence), its powerful mind-altering properties and its colossal stature. The Blue Meanie mushroom potency is known to contain exceptionally high level of baeocystin, one of the psychoactive compounds present in magic mushrooms.

Indigenous to Hawaii it is also referred to as the “Hawaiian Blue Meanie” or “Natal Blue Meanie”. Its dung-loving nature is a factor that has greatly expanded its distribution.

Dung is a vessel for ultimate proliferation, it acts as a travelling substrate and has allowed the Blue Meanie cubensis to spread outside of Hawaii.

This is how Panaeolus cyanescens Blue Meanies came to make its way inside the hearts of many cultures worldwide.

The Samoans, Indonesians and Hawaiians, who all share ancient history with this magic mushroom, would refer to the Blue Meanie being the “perfect alchemist” that “transforms dung into gold, into the golden light of enlightenment”. The Blue meanies mushroom undeniably is amongst one of the most appreciated magic mushrooms out there.

The Blue Meanie mushroom effects reflect through the numerous endearing names it is given. With nick0-names such as Faleaitu (Samoan,“comedy house”), Pulouaitu (Samoan, “spirit hat”), Taepovi (Samoan, “cow patty”) and Ambur/Jamur (Indonesian, “golden mold”), it is impossible to ignore, the Hawaiian Blue Meanies potency foster euphoria.

The relationship these cultures have with Panaeolus cyanescens Blue Meanies is yet another witnessing of the special power of laughter and the respect it deserves.

After all, laughter is a legitimate therapeutical tool; it enhances our intake of oxygen, stimulates our heart, lungs, and muscles, and overall contributes to relaxing us. The Blue Meanie mushroom effects are known to tense and release _ from tension to deep release, they foster a sense of lightness, and relieve us from stress.

Because Pan Cyan has been around for so long, it left traces in literature. Reports describes colourful accidental intoxications “filtering sight through a green hue and turning walls into animated fractals”. Fortunately, none have been proven to be poisonous. The Blue Meanies mushroom effects aren’t just deeply euphoric, they are also very visual.

Even though people call the Blue Meanie mushrooms “cubensis”, they aren’t.  They are not from the Psilocybe genus, they are from the Panaeolus genus. Though the faulty comparison is understandable as the Pan cyanescens stature and resistant nature reminds that of the Psilocybe cubensis. Also, they share a common choice of substrate: dung.

Psilocybe authority Paul Stamets suspects that the quality of the substrate can affect the potency. With no doubt, the Blue Meanie mushroom potency is one that reflects its rich tropical substrate.

Found growing naturally in the USA in Hawaii, Louisiana and Florida, the Blue Meanies mushroom is also widespread in most semitropical zones such as Brazil, Mexico, Bolivia, the Philippines, eastern Australia and the Mediterranean region. The Panaeolus cyanescens Blue Meanies relatives include Panaeolus tropicalis and Pan. cambodginiensis, 

Also called the “Blue Hawaiian mushroom”, the Pan cynescens can occasionally be mistaken for Psilocybe cyanescens aka Wavy Caps with which it shares the same abbreviation.

Surely, the wavy cap of P. Cyan are distinguishable from those of the Blue Hawaiian mushrooms , along the fact that the former is a wood-loving specie whereas the ladder (Pan cyanescens) grows on dung.

It is said that the sudden appearance of the Blue Meanie mushroom within the European soil was established via imported Indonesian race-horse feces. In the early seventies, Blue Meanies were reported growing in Budapest Fairgrounds near the pavilions from Thailand and Vietnam only. Coincidence?

Meanwhile, in the early 1960s, in the South of France, several strange mushroom “intoxications” were reported. The faulty fungi were identified as the tropical species Hawaiian Blue Meanies.

Perhaps these series of strange mind-altering intoxications contributed to giving the species its common name: the Blue Meanies mushroom, the “golden mold”, the “spirited comedy hat” that readily turns blue and can bring you on a “mean” trip.

Amongst its many glories, the Blue Meanie mushrooms have been investigated as a possible therapeutic for anxiety, depression, and mood disorders. To this day research continues, and the use of psychoactive substances to help in psychiatry is being explored.

Today, the Blue Meanie is amongst the popular magic mushroom strains cultivated both indoors and outdoors. It is surely an ultimate favourite for psychonauts in seek of a good laugh or as the Samoans would say: in seek of a visit to the Faleaitu (Comedy House).



Visual Description

• Cap: 1.5-3.5 cm broad. At first hemispheric, to bell-shaped to convex in age. When young, margin has translucent striates and are is decurved soon to be opaque and decurved, often split and irregular in maturity. Cap with horizontal irregular cracks in age and in drying. Coloration light brown at first, becoming pallid grey, with disk remaining brownish. Quickly turning blue when bruised. • Gills: Mottled, graying black at maturity. Attachment adnexed, thin, close. • Stem: 85-115 mm long by 1.5-3mm thick. Equal, often thicker at base. Coloration pale yellowish, often grayish around apex and darker brown at base. No partial veil, readily bruising blue. • Spore print: black • Microscopic features: 12-14 by 7.5-11 micrometres. • Taste and odor: Farinaceous


MODERATE 0.25% - 0.75% HIGH > 0.75% - 2% 0.71% psilocybin, 0.04% psilocin, 0.01% Baeocystin. Rumors in the scientific world report that further studies by famous entheo-mycologist John Allen on a specimen found in Thailand showed that it may contain more psilocin than psilocybin (0.4-1.05% psilocin with trace amounts of psilocybin). This would explain previous analyses by Hofmann registering levels of only 0.2% psilocybin.

Habitat Origin

Found in Hawaii, Florida and Louisiana. Widespread in most semitropical zones such as Mexico, Brazil, Bolivia, Indonesia, Thailand, India, the Philippines, eastern Australia. Reported in the following regions: Europe, USA, Asia, Mexico, south and central America, Oceania, Africa, the Caribbean. Growing in small-dispersed amount to gregariously in dung in pastures and fields. Fun Fact: Psilocybe authority Stamet who reported a Pan. cyanescens when invited to identify a specie growing in a garden near Tenino, Washington, from which the yard had been fertilized with horse manure. The manure came from a local horse stable which had recently received horses form Florida. Yet another example of the expansion of fungi distribution through livestock.


Needless to say, this highly potent strain has the reputation of altering the minds of those who consume it: an accidental intoxication from a family of four who reported seeing only “in shades of greens with intense animated geometric shapes appearing from the wall”. --- Described as a quick and powerful come-up with long lasting intense visuals and an intense body trip. Very high dosages can result in loss of muscle control. In Samoa, it is said that regular use of the mushroom will produce a painful red rash around the neck. This may be due to the presence of urea (Stivje 1987, 1992). --- John Allen, famous and passionate entheo-mycologist (Psilocybe Allenii was named after him) consumed 20 Pan Cyan while on a trip in Hawaii and described the following effects: connectedness to the universe, strong visual hallucinations, vivid colours and enhanced senses. Stronger dosage can nurture a twisted sense of time and space and mind bending visuals. Said to increase creativity and energy. ---- Psilocybe authority Stamets, reported a Blue Meanie growing in a garden near Tenino, Washington. The yard had been fertilized with horse manure from a local stable which has recently welcomed horses coming from Florida. Yet another story that shows how fungi distribution expands through livestock!
