Created in response to requests from longtime users, this companion to the acclaimed reference to North American lichens compiles updated and expanded keys for the identification of these fascinating organisms. An ideal laboratory resource, it covers over 2,000 species of lichens indigenous to the continent. There is no comparable volume available for classroom, workshop, or private use. A glossary is illustrated with photographs by Sylvia Duran Sharnoff and Stephen Sharnoff and drawings by Susan Laurie-Bourque, all from the original book. The revised keys are an indispensable identification tool for botanists, students, scientists, and enthusiasts alike.
Considered a world authority on lichens and their biology, Irwin M. Brodo is emeritus research scientist at the Canadian Museum of Nature, Ottawa, Ontario.
"This updated and much expanded identification guide accomplishes a feat no one else has dared attempt. It is extremely useful for non-professionals and professionals alike."
– Richard Harris, New York Botanical Garden
"Brodo is responsible for the renewal of North American lichenology. In this new volume, he updates the keys to North American lichens to accommodate rapid changes in lichen systematics and taxonomy in the beginning of the 21st century. Using these new keys with Lichens of North America, individuals, study groups and classes can identify many species in any region of North America."
