Check your local community college for mycology classes offered. Even if none are listed, call the biology department office and ask if there are unofficial field trips by any profs or TAs. The way to develop experience is to go out with experienced mycologists. Certainly books expand your knowledge, but in this field of study, one error in judgment "Gee, it looks exactly like the one in the book. I think it's okay to eat it" could cost you your life! You will pick up so much faster with a group, and erring on the side of caution will be imprinted on you forever. Don't want to scare you off. Just want you to have an enjoyable lifetime experience! Just because a book lists a mushroom as edible doesn't mean that it will be always edible for you. Some mushrooms fumes should not be inhaled when being cooked as the fumes are very toxic. 8O It's a fascinating world. Enjoy!
