ALLEN STRAIN aka PSILOCYBE SAMUIENSIS
Psilocybe samuiensis was the first bluing Psilocybe recorded from Thailand and the first species found outside of Mexico directly related to P. mexicana. It therefore belongs to the hallucinogenic fungi section Mexicanae. It also bears a striking resemblance to P. semilanceata aka Liberty Cap but hasn’t yet gained the name Thai Liberty Cap.
Found and documented in 1991 by ethnomycologist John W. Allen, it was growing in rice paddie fields near the Muslim village of Ban Hua Thanon, on the island of Koh Samui in Thailand. Today, this popular strain is often simply called Koh Samui or Thai. Perhaps because it was first found by Allen, consumers may refer to it as the Allen strain, though another specie from the Bay Area California already bears his name: Psilocybe allenii.
This strain from the province of Ranong was also found around the famous temple of Angkor Wat in Cambodia. Even though it is considered rather rare, it is said to be easily cultivated, which is a common practice amongst the villagers and farmers of its native regions. The growth of P. samuiensis is said to be similar to that of Floridian native P. tampanensis, in that it is resistant to contamination and a fast-colonizer. Connoisseurs refer to it as a “super strain”.
With considerable destruction of tropical habitats for use as agricultural or cattle farms, many species will likely disappear before being documented, cultivation somehow helps preserve the continuity of the endangered tropical mycoflora.
Psilocybe Samuensis Koh Samui today is known, consumed and cultivated worldwide and particularly amongst knowledgeable users. Its relatively strong effects doesn’t make it the ideal candidate for beginner psychonauts.
