The psychedelic compound typically found in mushrooms (psilocybin mushrooms). They’ve engineered bacteria to produce psilocybin in their cells and poop it out, in gram-scale concentrations that are higher than any other bioengineered organism to date. See our psilocybin spores (mushroom spores).
Psilocybin is similar to LSD in that its chemical structural backbone is the same (a substance called an “indole”). Its effects are similar to both LSD and mescaline and there appears to be some cross-tolerance among these three hallucinogens. Dried mushrooms contain approximately 0.5% psilocybin. The most effective dose seems to be about 5 mg, with higher doses causing some unpleasant effects.
mushroom, the conspicuous umbrella-shaped fruiting body (sporophore) of certain fungi, typically of the order Agaricales in the phylum Basidiomycota but also of some other groups. Popularly, the term mushroom is used to identify the edible sporophores; the term toadstool is often reserved for inedible or poisonous sporophores. There is, however, no scientific distinction between the two names, and either can be properly applied to any fleshy fungus fruiting structure. In a very restricted sense, mushroom indicates the common edible fungus of fields and meadows (Agaricus campestris). A very closely related species, A. bisporus, is the mushroom grown commercially and seen in markets.
Umbrella-shaped sporophores are found chiefly in the agaric family (Agaricaceae), members of which bear thin, bladelike gills on the undersurface of the cap from which the spores are shed. The sporophore of an agaric consists of a cap (pileus) and a stalk (stipe). The sporophore emerges from an extensive underground network of threadlike strands (mycelium). An example of an agaric is the honey mushroom (Armillaria mellea). Mushroom mycelia may live hundreds of years or die in a few months, depending on the available food supply. As long as nourishment is available and temperature and moisture are suitable, a mycelium will produce a new crop of sporophores each year during its fruiting season.
