Paul Stamets is great in that he has made mycology a little more accessible to laypeople, BUT please understand that the man is a snake oil salesman who presents his own half-baked theories as scientific truths. It’s unfortunate that there aren’t better resources out there for non-scientists to learn more about mycology, especially if you’re interested in learning about fungi that aren’t mushrooms. I hope to change that, someday, when I am not being consumed alive by grad school, but in the meantime here’s a list of decent intro to mycology books (which are relatively technical but don’t let that scare you).
