<unk>  is the collective name of a subgroup of at least nine related toxic compounds found in three genera of poisonous mushrooms (Amanita, Galerina and Lepiota) and one species (Conocybe filaris) of the genus Conocybe. From the amanita, the most notably is the death cap (Amanita phalloides).<unk> s are lethal in even small doses, as little as half a mushroom, including the immature 'egg' form which appears quite different from the fully-grown mushroom. Although laboratory analysis has found that the spores contain as little as 3% the toxin concentration of the main mushroom body, anecdotes have been repeated in field guides that claim foragers have fallen ill from spores alone after collecting but then discarding toxic Amanitas, unknowingly leaving their spore dust on the remaining harvest. Unlike many ingested poisons, they cannot be destroyed by heat without destroying the mushrooms beyond edibility first, so cooking the poisonous mushrooms does not diminish their lethality.
