The very first book about mushrooms that I bought was Fischer and Bessette’s Edible Wild Mushrooms of North America: A Field-to-Kitchen Guide, at the Mammoth Cave National Park Visitor Center. Since then, I have bought, and given away and bought again, four copies. The book has three sections: Edibles, Poisonous look-alikes, Recipes.
For the edibles, they present a large picture and bullet points, or criteria, that must be met for correct identification. They then contrast with the bad look-alikes.
I love this book for its simplicity and the fact that the 20 or so edibles cover all seasons of the year. One can always be hunting for something in the book, not just in spring and fall.
