This volume is the first guide to identify mushroom species not commonly classified or illustrated elsewhere in current literature. The book, which will serve as a companion to other popular field guides, shows how to distinguish lesser-known mushrooms from other common fungi. Found in a variety of habitats in North America, each species has an accurate and up-to-date description, a color illustration, and detailed information on its distinctive species characteristics. The book is written for the amateur and professional mycologist alike. Anyone, however, who is interested in collecting mushrooms will find it a valuable contribution to the field.
