Psilocybe Samuiensis is a relatively popular recreational mushroom given its rarity and restricted range. It is rarely found outside of Thailand, occasionally in Cambodia. More specifically, the species is most commonly found in the Thai province of Ranong, on the island of Koh Samui from where it gained its name. Either introduced by tourists in the 60s and 70s, or arising naturally among the local populations. After years of contentious debate on its identity, P. Samuiensis became the first of the Mexicanae group of Psilocybe species to be found outside of Mexico.
The confusion regarding its identification arose from the many similarities it shares with other members of the Psilocybe genus. Originally mistaken for P. Mexicana or P. Semilanceata, these options were eventually discounted, as neither is known to grow in Southeast Asia. P. Samuiensis grow in sandy, clay-rich soils of meadows and rice paddies. It is found fruiting in late summer alongside other Psilocybe species, making them relatively rare compared to the others. Their small size may contribute to this perception, as they are frequently overlooked for bigger or more potent species.
Though small, this species is considered to have a moderate to high potency. It contains psilocybin, high levels of psilocin and trace amounts of baeocystin. At a maximum size of only 5-7.5 centimeters. Another one you need to have in your research collection! This one is rare!
