A prolifically fruiting Psilocybe cubensis variety collected near the Angkor Wat complex by ethnomycologist John W. Allen in the mid-1990s.
§ 01Morphology
Cambodian fruits are mid-sized, with caramel-coloured caps of 30–70 mm and a slender but firm stipe. Mycelial growth on grain substrates is markedly rhizomorphic, a trait that predicts the variety's rapid colonisation and prolific fruiting tendencies.
Flushes are dense, with numerous specimens per substrate surface area. Bruising reaction is standard blue-green and spore prints mature to a uniform deep purple-black.
§ 02Origin & Naming
The variety takes its name from the country of origin. John W. Allen — whose ethnomycological fieldwork across Southeast Asia in the 1990s contributed several lineages to contemporary cultivation — collected the original material near the Angkor Wat temple complex around 1994.
The variety has since been widely distributed through community networks. Variations distributed under labels such as Cambodian Gold or Angkor Wat are best treated as parallel selections rather than distinct genetic lines.
§ 03Cultivation Temperament
Cambodian colonises grain substrates notably faster than most P. cubensis varieties, which has made it a popular first choice for novice cultivators alongside Golden Teacher and B+. Pinning is typically early, and flushes are dense if individually moderate in specimen size.
The variety is broadly tolerant of substrate and environmental variation and fruits readily on CVG, coco-coir, and pasteurised straw preparations. Contamination resistance is typical of the species.
§ 04Safety Profile
As with all psilocybin-containing species, Cambodian carries significant contraindications. Psilocybin is a serotonergic compound and interacts with a range of medications and mental-health conditions.
⚠ Contraindications
Not suitable for individuals with personal or family history of psychotic disorders, schizophrenia, or bipolar I; those taking SSRIs, MAOIs, or lithium; pregnant or breastfeeding persons; or those with unmanaged cardiovascular conditions. Always review the full safety codex before use.
