Allen Strain (AS) Allen strain is (believed) to be an offshoot of the famous 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. 

Allen shrooms are named after “Mushroom” John Allen, an ethnomycologist credited with discovering some of some of the most popular strains in the world including Ban Hua Thanon, Burma, Cambodian, Corumba, Hanoi, Kathmandu, Malaysian, Thai and many others.

Mushroom John discovered and collected various 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, but John Allen would simply name the samples after the regions he collected them.

Today the continuation of stock John Allen collected persists on the market. 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.
