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.
Don't forage for mushrooms unless you identify them in multiple ways, from multiple guidebooks, and ask locals what's around, first.
There are quite a few types of mushrooms that don't have any poisonous lookalikes, that is once you know what to look for.
Oyster mushrooms, golden (and winter) chanterelles, puffballs (IFF you slice them and make sure there's no 'mushroom' outline within!!!), hedgehogs, boletes.
My knowledge is restricted to the PNW (Pacific North-West) however, so also read on regional variations.
