If you’re interested in exploring the subject and finding edible species, the best way to learn is in the field with an expert. This is very important because if you eat the wrong ones, you may get very sick. and perhaps even die.

If you believe a mushroom made you sick, call the Rocky Mountain Poison Center at 800-332-3073. Remember that proper treatment of mushroom poisoning depends largely on rapid identification of the type of poison at hand. Always save a sample of any mushrooms you collect and eat.

There are several excellent guidebooks that allow do-it-yourselfers to identify at least a few basic species accurately. The Audubon Society Field Guide to North American Mushrooms (Chanticleer Press, 1981) has an extensive listing of species that grow in Colorado and the rest of the continent. The Audubon guide works best when used in conjunction with a new, state-specific guidebook by Vera Stucky Evenson, curator at the herbarium of fungi at the Denver Botanic Garden.

Evenson’s book, Mushrooms of Colorado and the Southern Rocky Mountains (Westcliffe Publishers, Inc., 1997), describes varieties that are commonly found in our state, including edible and poisonous species. Using more than one guidebook allows hunters to cross-reference descriptions and photos for more accurate identification.

It’s crucial to actually read the text in the books, and follow the steps to identification exactly. Don’t just try to match specimens in the field to the pictures. — B.B.
