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.
For those who have experience, yes – but to the inexperienced eye, there are some false morels that can definitely trick people.

We have some Gyromitra that pop up every year in one area of our backyard. They produce a molecule, gyromitrin, which is metabolized in the body into monomethylhydrazine, which is used in rocket fuel(!)… So be careful.
Apparently Gyromitra are consumed in Europe by some – but only after careful preparation… I am not brave enough to try that :/
