Origin

Named in honor of Terence McKenna. Its origin is uncertain: accounts suggest either a spore print from McKenna’s collection after his death or development by a Dutch cultivator. An expert cited by DoubleBlind says genomic sequencing supports the Dutch-origin account.

Lineage

Reported to be genetically almost identical to Golden Teacher; one expert suggests the name may be a marketing name for a Golden Teacher-like variety. Its genetic stability is uncertain.

Appearance

Described as medium to large, with light-to-dark brown caps, thick stems, and dark, nearly purplish spores.

Cultivation

Sources differ: Sirius calls it slightly more difficult, while DoubleBlind sources describe it as intermediate or relatively easy to grow, with good yields. Zamnesia advertises multiple flushes and reports from customers vary.

Reported effects

Retailer descriptions emphasize strong visuals and an intense, philosophical experience. DoubleBlind’s cited experts note that reported effects may be similar to other cubensis varieties, including positive mood and mild visuals; accounts of strength vary.

Good to know

The strain’s association with Terence McKenna is clear, but the story of how it originated is disputed.
