Be very cautious!
I used to study mushrooms, and grow a few
The only advice I can give is: Having a book to HELP identify is NOT enough! You can destroy your liver in two hours with the wrong kinds. If you want to make collecting mushrooms a part of your life, you need to study. You need to be able to classify and identify mushrooms, and compare similar species. Many people have become sick from eating an "edible" mushroom, but it was actually just a few gill segments away, and was a Death cap.
It can be very enjoyable and fun, but learn your stuff!!!
Get three or four books from the library, read them, go out identifying. Several times. Take mushrooms home and identify them, and scrutinize them. After enough of this you will note the differences.
Another note, on the Amanita Muscaria, or toadstool mushroom. The one with the huge red cap and little white freckles on it. It is very easy to identify, very widely known, is very psychoactive, and is also very poisonous.
