“Blue Meanies” are a common name for Panaeolus Cyanescens mushrooms. They are a different species from the more common magic mushroom species Psilocybe Cubensis.
Panaeolus Cyanescens are much, MUCH more potent than Cubensis strains containing upwards of 2x the amount of psilocybin and psilocin.
You should take half your normal dose of Cubensis to establish potency and effects.
Several pictures for help in identification can be found here.
As always you should use extreme caution when eating wild picked mushrooms. Certain species of mushrooms are toxic and fatal if eaten. Be safe.
Everyone’s physiology and metabolism are different, and individual brain chemistry and body size play a significant role in how each individual might respond to psilocybin, as will your surroundings and emotional state, so if it is your first time or you are significantly upping your dosage, select a safe, comfortable, and if possible, familiar place, and consider asking a sober trip sitter to be your companion for the coming ride.
Effects begin between 10 to 40 minutes after ingestion and can last between 3 and 6 hours, depending on the dose and the individual. Like all tryptamines, psilocybes often cause what has been called “the mushroom yawns” which increase markedly as one begins to peak, however, the feeling in the rest of the body is energetic, not tired. Users can expect a wide variety of possible effects and sensations, from the mystical, euphoric and revelatory to the hyperspatial and mind-altering observational. At doses over 2 grams, some users report experiencing warping of the visual field, and Dali-esque melting objects, and other possible effects include time distortion, hallucinations both when eyes are closed or open and synesthesia (i.e. “seeing” sounds and “feeling” colors), particularly with the Transkei variety of cubensis, which also tends to have a heavier body load. Remember to stay hydrated, especially if you’re outdoors or doing activities like dancing, and try sipping some honey ginger tea to counteract any possible nausea during the come-up. Do not use if pregnant and do not mix with other drugs, especially alcohol.
