Context: after eating a death cap (Amanita phalloides), you’d notice a few of the symptoms at first, but these usually resolve after a day or two. After this, you’ll enter a latent phase where you feel fine, but your liver and kidneys slowly start to fail. By the time you notice, it’s usually already too late.
If all mushrooms are edible but some are only edible once, the latency makes the death cap one of the few mushrooms that’s edible a few times.
