In the US, it’s explicitly psilocybin (and maybe psilocin too) that is federally banned. This is why you can still legally buy spores of the mushrooms that contain it: the compound does not exist in the spores. This is almost certainly due to an oversight when the law was written. Legality is weird. In the Netherlands, over 100 species of psilocybin-containing mushrooms were banned. But the law there bans only the fruiting bodies, it does not ban other parts of the organism. A few species form truffles—a sterile mycelia mass for energy storage, kind of like its version of a potato—that still contain psilocybin. Those can still be legally bought, probably because of a similar oversight in the law.
