Mushroom species

Each species page links to the cultures that use it, and covers habitat, chemistry, ritual role, and what stays uncertain. A cultural and historical reference — not a cultivation or consumption guide.

Chemistry
Evidence
A fly agaric, Amanita muscaria, with a brilliant red cap flecked with white, growing in leaf litter.
Muscimol / ibotenic

Amanita muscaria

Fly agaric · fly amanita

The fly agaric — a genuinely toxic, muscimol-bearing mushroom (not a psilocybin species) at the centre of documented Siberian ritual use and a long train of disputed theories, from Soma to berserkers to Christmas.

Historical

A blue-bruising Asian bolete — no gills, no psilocybin, no muscimol — reported to bring vivid visions of tiny people. Communities in Yunnan, Papua New Guinea, and the northern Philippines describe the same effect independently, and no one yet knows what compound causes it.

Newly documented
Psilocybe aztecorum mushrooms photographed against a black background, caps bruising blue.
