Key Identification Feature

Black spore print (distinguishes from Psilocybe which has purple-brown). Mottled gill appearance. Intensely blue on bruising. Dung or fertilized soil habitat.

⚠ Dangerous Lookalikes

Panaeolus foenisecii (no bluing; not psychoactive), Coprinoid species (deliquescent gills; no bluing), Agaricus spp. (different ecology; brown spores)

Notes

Black spore print (vs purple-brown in Psilocybe) is the key distinguishing feature. Often called 'Blue Meanies' in Australia and Caribbean where it grows prolifically on cattle dung. Not to be confused with Psilocybe cubensis variety 'Blue Meanie.'

Legal Status Warning Psilocybin-containing mushrooms are controlled substances in most jurisdictions. This guide is for educational purposes only.
