Psilocybe allenii is one of the new species of psilocybin mushrooms. Discovered in 2012, it got its name from John W. Allen who provided the type collection.

The fruiting bodies of P. allenii vary in size and are entirely dependent on the substrate where it grows. Its caps can range from 1.5cm to 9.0cm in diameter, and range from broadly convex to flat with a slight depression in the center at times. The cap’s margin is either straight or slightly curved inward, rarely slightly wavy, and sometimes has radial grooves in moist specimens.
- Allenii’s surface is smooth but becomes sticky with moisture, and its cap has a cuticle than can be peeled off. When wet, the fruit bodies become so slippery they’re a challenge to collect. This fungus is also identifiable because of its pale, orange brown to caramel brown caps which dry to yellowish buff.
Its stem, or stipe, is cylindrical and hollow with lengths typically measuring 4 to 7 cm with a slightly thicker base connected to thick white rhizomorphs. The top of the stipe is covered with white powdery granules. The stipe’s surface is smooth and looks as if it’s made of silky, slender fibers and its color is initially white but turns yellow with age. The odor and taste of this mushroom is starchy similar to freshly ground flour.
Young species of P. allenii are covered with a white, partial veil that eventually disappears or remains as a zone on the stipe that can be colored purplish brown by spores. Spore prints of P. allenii have dark brown spore prints with shades of violet. When handled, the fruit body stains blue or purplish in the handled parts.
Tripping off Psilocybe Allenii
Psilocybe allenii are popular for their psychoactive effects, just like all the other psilocybin mushrooms. They have a potency similar to P. cyanescens which is approximately 0.85% psilocybin. If you visit the Golden Gate Park in December you will see hundreds of mushroom fans scouring the wood chip landscape for a handful of this hallucinogenic mushroom.
Shrooms such as P. allenii contain two potent chemicals, psilocybin and psilocin. These two compounds are responsible for the mushroom’s psychedelic effects. These effects are euphoria, altered thinking, cross-over of the senses, and spiritual awakening.
The rules for tripping on Psilocybe allenii is similar to tripping on any species of magic mushrooms.
Dosages play a big role on the effects P. allenii on the body. The threshold dose is 0.25g dried mushrooms. This won’t cause you to hallucinate and you will still be able to go through your day normally but you will still undergo changes in sensation including feeling cold and seeing more vibrant colors.
The light dose ranges between 0.26g to 1g. Depending on your tolerance, you will start to see mild symptoms such as seeing more saturated colors, hallucinations at your peripheral vision, and fleeting visual distortions. Walls, ceilings, and paintings will start shimmering or appear to breathe. Pupils will also become dilated and the hands will be cold and clammy. Even your thought processes will change.
The regular dose, or the common dose, ranges between 1.1 to 2.5g. This leads to more intense hallucinations including visual patterns and hallucinations that persist even if you close your eyes. Synesthesia, or the crossover of senses, is one of the most popular effects on a common dose and this is when trippers start seeing sounds and hearing colors.
And finally, a strong dose starts from 2.5g up. This amount of dried Psilocybe allenii is known to give you intense visuals and will distort your sense of time. 6 hours may have passed but you will feel you’ve been tripping for days. Users also report spiritual and personal awareness and an enhanced perspective of the world.
Just like most magic mushrooms, Psilocybe allenii kicks in after 30-60 minutes, peaks within 90 minutes to 2 hours, and lasts for 3-8 hours.
In the long-term, tripping on magic mushrooms such as P. allenii is shown to improve overall mental health, creativity, and even boost work performance.
Psilocybe Allenii Habitat

Psilocybe allenii is found in the northwestern North America extending from British Columbia south to Los Angeles, California. It is most common in areas 16 kilometers from the Pacific coast but there are cases where it was found 160 kilometers inland.
This fungus grows scattered in groups, or more rarely in clusters on woody debris, such as wood chips, often used in landscaping. P. allenii favors growing on hardwood mulches made of oak, eucalyptus, Douglas fir, and alder. Fruiting takes place during the colder seasons, generally from late September to January.
Growing Psilocybe Allenii
Psilocybe allenii cultivation is similar to growing other types of magic mushrooms. This procedure requires having a substrate made of brown rice flour, vermiculite, and water which will feed and supply water to the magic mushrooms. These are then kept in jars and sterilized in a pressure cooker, or boiling water to kill anything that can potentially contaminate the mushrooms.
Once sterilized and cooled, mushrooms spores are added to the substrate using a syringe. The spores then germinate and colonize the entire jar. It works best if the jars are kept in a dark place around 75 to 85 degrees F. The resulting cakes are removed from the jars when fully colonized an placed in a terrarium with temperatures between 75 and 80 degrees until the mushrooms start to grow from the cakes.
As soon as the mushrooms form, it’s best to transfer them to a place that gets a little bit of light with 90-95% humidity. When mature, they can be harvested, dried, and consumed. The Psilocybe allenii you produce on your own will feel more rewarding.
If you can’t go through the entire process of growing Psilocybe allenii, you can simply order a Psilocybe allenii grow kit online and experience these magic mushrooms for yourself!
What if you find them, but by the time you get back to harvest they are already starting to dry out? Can they still be harvested although less potent??
