Just re-watched the 1980 Ken Russell film Altered States, and there was my old friend Amanita muscaria. Supposedly being gathered in the desert of Mexico and used in indigenous rituals, then made into some sort of liquid that the doctor transports back with him and continues taking, with insanely psychedelic effects.
Wrong climate and growing conditions, wrong preparation, wrong effects and wrong cultural usage. Typical for Amanita portrayals but still always a little disappointing. Interesting, though, how this mushroom keeps being selected as the classic trippy fungus, despite many other more suitable candidates.
