Nepal Chitwan.

What's known

Here's what's meant to be true and not.

What we actually know

• It is a plain Psilocybe cubensis: a wild geographic collection, not a hybrid and not a separate species.
• It is named for the Chitwan region of southern Nepal, in the Terai lowlands near the Himalayan foothills, where cubensis grows in a warm subtropical climate.
• By the widely repeated account it was collected on what appeared to be elephant or rhino dung, fitting cubensis as a coprophilic (dung-loving) species.
• It drops a dark purple-brown spore print, the normal normally coloured cubensis colour, with no albino or leucistic trait reducing the deposit.
• Reported spores sit around the species norm, roughly 13 x 8 um, smooth and subellipsoid with a flattened germ pore.

What the community says

• The collection is usually credited to a gatherer remembered only as "Baerbel", said to have found three specimens in the village of Sauraha near the Chitwan jungle. Treat this as a single-source origin tale rather than firmly documented history.
• The specimens were growing in otherwise dry conditions, shaded by a nearby tree, on what looked like elephant or rhino dung. A nice detail, but unverified.
• Because it carries a real-sounding place name, it is sometimes marketed as wildly potent or exotic. It behaves like any other cube, a cube is a cube.
• Some sellers blur "Nepal" and "Chitwan" into one catch-all Himalayan strain. The specific strain collectors trade is the Chitwan collection, not a generic Nepalese cube.

Where it came from

Most famous cube names are forum nicknames or vendor inventions with no real geography behind them. Nepal Chitwan is one of the more believable exceptions. It is named for the Chitwan region of southern Nepal, the warm Terai lowlands at the foot of the Himalayas, an area better known for its national park, its rhinos and its elephants than for its fungi. As a coprophilic species, Psilocybe cubensis follows large grazing animals wherever the climate is warm and wet, and the dung of Chitwan's megafauna is exactly the kind of substrate it favours.

The collection story that travels with this strain credits a gatherer remembered only as Baerbel, who is said to have found three specimens in the village of Sauraha, on the edge of the Chitwan jungle. The mushrooms were reportedly growing in otherwise dry ground, shaded by a tree, on what appeared to be either elephant or rhino dung. It is a specific anecdote, and it gets repeated almost word for word across the hobby. That's why it pays to hedge it. One consistent account is not the same as documented history.

It is one of the few cube names where the place on the label might actually mean something. The caveat is that the whole origin rests on a single collector's account.

What to expect at the scope

Whatever the truth of the Sauraha story, the genetics are not exotic. Growers on the forums are blunt about it: it is a cube like any other, with some reporting it is a touch slower to get going. There is no evidence it is unusually strong, and the "rare Himalayan superstrain" framing some shops lean on is marketing, not mycology. What you get is a characterful collection with reddish cinnamon caps and a clean dark print, and a name that, for once, points at a real spot on the map.
