Computer illustration of a fly agaric (Amanita muscaria) mushroom and molecule of muscimol toxin, the principal psychoactive constituent of the fly agaric. These poisonous mushrooms are the fruiting bodies of the Amanita muscaria fungus. The caps can be dried and used for their hallucinogenic compounds. This fungus is commonly found among birch trees in temperate regions, fruiting in the autumn. Atoms are represented as spheres with conventional colour-coding: hydrogen (white), carbon (grey), oxygen (red), nitrogen (blue). |
