I'm somehow skeptical of the history. I would love to see a copy of the book before believing it truly.

It seems really crazy to me to just pick a book online and go away picking and eating mushrooms happily without apparently any previous knowledge. Specially those that are not the most commonly known as safe to eat.

Even if the book was not inaccurate and Ai generated. It seemed like a recipe for a very bad time. From a book picture to the real thing there can always be doubts and some experience and contrasted sources for investigation are must. Including you know.. just searching online, seems like a basic thing to do while foraging things that could kill you if you identified it wrong.
