Peterson Field Guide To Mushrooms is a portable-sized field guide for mushroom identification—the ultimate, most comprehensive manual to mushrooms available. 

Toadstools, truffles, boletes and morels, witches’ butter, conks, corals, puffballs and earthstars: mushrooms are both mysterious and ecologically essential. They can also be either delicious or deadly. Thousands of different species of mushrooms appear across North America in the woods, backyards, and in unexpected corners. Learning to distinguish them is a rewarding challenge for a naturalist or chef. Covering most of the common edible and poisonous species readers are likely to encounter, this portable-sized field guide takes a new, simple approach to the method of mushroom identification based on key features that do not require a microscope or technical vocabulary. In addition to the watercolors from the original edition, hundreds more illustrations have been added.

For more than 85 years, Peterson Field Guides have set the standard by which other field guides are measured. Comprehensive and authoritative, they are essential additions to any naturalist's bookshelf or backpack.
