oop, might have to take back (partially?) my glowing praise for the Penguin, cause there's some mushroom misinformation in it.
at least they're using a real mushroom, Hydnellum peckii, the bleeding tooth... and the way it looks is somewhat accurate (except that it doesn't have a stem, and cannot be cultivated so far as i know). but the red guttation on the cap is a) not psychoactive and b) is not the basidiospore (those are ejected where the "teeth" are, very similarly to gills.
