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 A cultural and historical reference — not a cultivation or consumption guide.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 brown-capped Amanita pantherina studded with white warts, with a ringed white stem.
Muscimol / ibotenic

Amanita pantherina

Panther Cap · panther amanita

The panther cap — fly agaric's browner, more dangerous cousin. It carries the same muscimol chemistry at higher and more erratic doses, and is a genuinely toxic mushroom that poisons people every year. A muscimol species, not a psilocybin one.

A bolete from the highlands of Papua New Guinea, collected in the Wahgi Valley.

Boletus manicus

nonda (a name applied broadly to several boletes)

The vivid bolete at the centre of the New Guinea 'mushroom madness' — identified by Roger Heim among the Kuma of the Wahgi Valley, and famous precisely because the psychoactivity attributed to it was never confirmed.

Mystery
A dense cluster of large tawny-orange Gymnopilus junonius mushrooms at the base of a tree.
Psilocybin

Gymnopilus junonius

Laughing Gym · spectacular rustgill

The 'Laughing Gym' — a large, bitter, wood-rotting orange mushroom whose psilocybin-bearing forms are linked to one of the oldest written mushroom stories on earth: Japan's waraitake, the laughing mushroom of a thousand-year-old tale.

Mystery
A Lanmaoa asiatica bolete — a pored, gill-less mushroom whose cut flesh bruises blue.

Little-people bolete · 見手青 jiàn shǒu qīng (blue-bruising bolete, Yunnan)

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 surfaced
Slender grey-tan Panaeolus cyanescens mushrooms with thin caps, bruising blue.
Psilocybin

Panaeolus cyanescens

Psilocybin

Psilocybe cyanescens

Wavy Caps

Wavy Caps — a potent, wood-loving psilocybe that has made a home in the woodchip and mulch of parks and gardens, spreading through the landscaped edges of cities across Europe and North America.

Psilocybin

Historical
Psilocybin

Psilocybe natalensis

Natal (a cultivation name)

A southern African psilocybe described from KwaZulu-Natal — one of the region's few named psilocybin species, and a marker of how recently, and how thinly, the continent's mushroom record is being written.
