Lichens are a unique form of plant life, the product of a symbiotic association between an alga and a fungus. The beauty and importance of lichens have long been overlooked, despite their abundance and diversity in most parts of North America and elsewhere in the world. This stunning book--the first accessible and authoritative guidebook to lichens of the North American continent--fills the gap, presenting superb color photographs, descriptions, distribution maps, and keys for identifying the most common, conspicuous, or ecologically significant species. The book focuses on 805 foliose, fruticose, and crustose lichens (the latter rarely included in popular guidebooks) and presents information on another 700 species in the keys or notes; special attention is given to species endemic to North America. A comprehensive introduction discusses the biology, structure, uses, and ecological significance of lichens and is illustrated with 90 additional color photos and many line drawings. English names are provided for most species, and the book also includes a glossary that explains technical terms. This visually rich and informative book will open the eyes of nature lovers everywhere to the fascinating world of lichens.

Based on the acclaimed reference Lichens of North America, this resource for the classroom, field, and laboratory presents updated and expanded keys for the identification of over 2,000 species of lichens indigenous to the continent, twice the number covered by previous keys. The book includes a glossary 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.--COVER.

A practical field guide to the common lichens found in the northeastern megalopolis, including New York City, Toronto, Boston/New Haven, Philadelphia, Baltimore/Washington, D.C., and as far west as Chicago Lichens are dynamic, symbiotic organisms formed by close cooperation between fungi and algae. There are over 20,000 identified species performing essential ecosystem services worldwide. Extremely sensitive to air pollution, they have returned to cities from which they were absent for decades until the air became cleaner. This guide is the first to introduce urban naturalists to over 60 of the common lichens now found in cities and urban areas throughout northeastern North America--in parks and schoolyards, on streets, and in open spaces. Divided into three sections -- lichen basics, including their biology, chemistry, morphology, and role in human history; species accounts and descriptions; and an illustrated glossary, index, and references for further reading -- the book aims to connect city dwellers and visitors with the natural world around them. The descriptions, exquisite photographs, and line drawings will enable users to enter the hidden world of lichens.
