Psilocybe aucklandiae is a psychedelic mushroom, which has psilocybin and psilocin as its main psychoactive compounds. It is in the section Zapotecorum of the genus Psilocybe.[1][2]


Psilocybe aucklandiae has a farinaceous smell and taste.

The cap is 1.5–5.5cm in diameter, conical to almost plane with age with the edges sometimes curling upwards and splitting. It often has a broad umbo. The colour ranges from dark chestnut brown to yellow-brown, bruising deep blue (sometimes appearing greenish or almost black) when damaged. It is hygrophanous and becomes light yellow-brown as it loses moisture.

The gills are cream to greyish fawn when young, maturing to dark violet brown, with off-white edges. They have an adnate attachment to the stipe.

The stipe is 40–100mm long and 0.5–1.5mm thick, with brown flesh that bruises blueish. It is finely pruinose, punctate at the top with whitish fibrils near the base when young or undisturbed.

Psilocybe aucklandiae spores are dark violet brown, oblong to ellipsoid, and 7 x 4 µm. [3]

Distribution and habitat[edit]

Psilocybe aucklandiae is found in native and Pinus radiata forests, often fruiting directly from clay. Its type collection was in the Waitākere Ranges near Auckland, New Zealand, though it is most commonly found in the exotic pine plantation of Riverhead forest.[4][5]
