This is a good example, albeit a bit sad, of how far detached much of modern society is from our roots. In communities where foraging is common, you learn about these topics as a child and the knowledge is passed down from generation to generation. Many mushrooms are edible, some specifically prepared, some raw, and some are even considered superfoods (!). Mushrooms are very much the trickster though, many of them interchangeably similar in appearance, and for the uninitiated it can be easy to mix up safe ones with dangerous ones.
