With an average potency and decent fruiting capability, the Allen strain is a great option for beginner growers and experts alike. The effects are considered about “average” to what you might expect from other magic mushrooms.Dan SimmsLast Updated: August 19, 2022PrintThe Allen strain is believed to be an offshoot of the popular Thai strain that was first collected in a sample of elephant dung several decades ago. Today, this strain is revered for its rapid colonization times and bulbous caps that flatten out so fast you can almost see it — letting you know when they’re ready to harvest. In this in-depth guide, we’ll be discussing the origin of the Allen strain, the effects you can expect when taking this strain, where to buy Allen shroom spores, tips for growing these shrooms, and much more.What Are Allen Shrooms?Allen shrooms are a specific strain of psilocybin mushrooms belonging to the scientific classification of Psilocybe cubensis. These shrooms, along with all others belonging to that species, contain varying levels of psilocybin and psilocin (the active hallucinogenic compound in magic mushrooms). Allen shrooms are named after “Mushroom” John Allen, who is an ethnomycologist credited with discovering some of the most popular shroom strains in the world — including Ban Hua Thanon, Burma, Cambodian, Corumba, Hanoi, Kathmandu, Malaysian, Thai, and numerous others. Mushroom John discovered and collected these samples in the 90s during an excursion through Southeast Asia (primarily Thailand) in search of magical mushrooms. At the time, the concept of individual “strains” of magic mushrooms wasn’t a thing, so John Allen would simply name the samples after the regions he collected them — and the names stuck. Today the continuation of stock John Allen collected persists on the market today. Vendors buy spores from other sources, cultivate them, and continue the cycle of spore distribution to keep these lineages going indefinitely.The sample was allegedly collected from a paddy field near Ban Hua Thanon near the Gulf of Thailand. It now remains one of the more popular shrooms strains available.Most users find that the experience of taking Allen shrooms is highly creative. This is a popular strain for microdosing for the purposes of tapping into new creative avenues.

This strain was initially found by Mushroom John, who is an ethnomycologist known for discovering several species of psilocybin mushrooms. Mushroom John took an excursion through parts of Southeast Asia, during which he discovered several shroom strains.The Allen strain was discovered in a paddy field near Ban Hua Thanon in Thailand. It was one of the first shroom strains discovered in Thailand, making it a significant discovery. It’s believed to be closely related to several strains that originated in Mexico.There is some debate as to which shroom strain is the Allen strain, as Mushroom John Allen discovered several unique strains throughout his research. Most people attribute the name to the strain discovered in Thailand, but some argue that his famous California-origin strain or the strain he discovered in Cambodia should be named after him.The Allen shroom — from Thailand — is one that is popular among growers for its rapid colonization time. It has an average potency but tends to elicit a somewhat powerful experience, which is likely one of the reasons this strain has remained as popular as it has.Allen Strain Potency & Psilocybin ContentMost users and growers want to know the potency of a strain — which is to say, the psilocybin content by weight — before they begin to grow it or use it to trip. Unfortunately, the concentration of psilocybin in a specific strain can vary wildly between samples. The growing conditions will affect the levels of psilocybin, often more than the specific strain, so you could find that some Allen shrooms have half the potency of others of the same strain. The John Allen Strain also commonly called the John W Allen magic mushroom, the Allen Psilocybe cubensis or the John Allen cubensis, is a famous magic mushroom from Thailand named after ethno-mycologist John W. Allen. Well renown, “Mushroom John” found this hallucinogenic specie in 1991 growing in rice paddy fields near the Muslim village of Ban Hua Thanon, on the island of Koh Samui.The John Allen mushroom strain was the first bluing Psilocybe recorded from Thailand and the first cubensis species found outside of Mexico directly related to P. mexicana. All these features make the Allen Psilocybe cubensis an epic Thai strain.Bearing a striking resemblance to P. semilanceata aka Liberty Cap, the John Allen magic mushroom hasn’t yet gained the name Thai Liberty Cap yet it is often referred to as the Thailand magic mushroom.With no doubt, the Allen magic mushroom strain is as popular and well established in Thailand as P. semilanceata is in Europe. Called Koh Samui, Thai Ban Hua Thai mushroom, or simply the John W Allen magic mushroom, there is a bit of ambiguity around which mushroom is actually the John Allen mushroom.A specie from the Bay Area California already bares Allen’s name, Psilocybe allenii mushroom, while another, Panaeolus cambodginiensis (also found by Allen), originates from the famous Angkor Wat temple in Cambodia.Probably because Psilocybe Samuensis is the species indigenous to Thailand found by Allen, it is most likely to be the specie consumers refer to it as the Allen Strain.Psilocybe samuiensis, which was originally found in Kho Samui, in the village of Ban Hua Thanon, is now also known to grow in the province of Ranong in Thailand, and around the Angkor Wat temple in Siem Rap, where Panaeolus cambodginiensis grows.The Kho Samui mushroom potency is known to be rather like that of its neighbouring relative Panaeolus cambodginiensis.Consumers report an energetic, physical, euphoric voyage with an actively visual twist.

It’s unclear why this relatively popular cultivar wasn’t entered into the competition.Allen Strain Variations & Genetic RelativesIn some cases, shroom strains are compared to and grouped with genetic relatives either because their effects or growing habits are similar to one another. In the case of Allen shrooms, the most similar strains come from Thailand.
