Key Identification Feature

Wood chip habitat in urban Auckland gardens. Blue bruising at stem base. Autumn-winter fruiting. Similar to P. subaeruginosa but smaller and lower potency.

⚠ Dangerous Lookalikes

Psilocybe subaeruginosa (also NZ, same habitat, higher potency and larger); Stropharia species (non-psychoactive, similar size and habitat)

Notes

One of New Zealand's endemic Psilocybe species. Commonly found in Auckland urban gardens and parks that use wood chip mulch. Often collected alongside P. subaeruginosa, which is significantly more potent. Estimated psilocybin content 0.4-0.8%.

Legal Status Warning Psilocybin-containing mushrooms are controlled substances in most jurisdictions. This guide is for educational purposes only. Wild foraging for psilocybin mushrooms may be illegal in your location. Never consume wild mushrooms without positive identification from an expert mycologist — misidentification can be fatal.
