Earlier quoted context omitted.
I know, right? What's the upside? Possibly interesting flavor. What's the downside. AGONY AND DEATH. Why is this even a question?
There's no risk of agony and death from foraging many edible species. If I'm foraging big orange pored shelf mushrooms, for example, my risk of death is zero. This is like saying "what's the upside of drugs when some of them kill you?!"
But above that, the risk is that you have misestimated your level of "knowing what you're doing".
So, the sensible thing to do is make the cutoff at the point where the risk of that error is lowest. And that point is "is it a wild mushroom?"
Or you can just assume your knowledge is good enough and risk becoming a Dunning-Kruger statistic.
