Based on fieldwork and research by the authors during the last 35 years, the Macrolichens of New England is the most comprehensive work of its kind. Ninety-eight genera and 461 species of macrolichens are described, with color photographs included for 308 species of them. The volume also includes, among others: introductory material on general lichen morphology and a glossary of terms for less experienced readers; advice on collecting lichens and performing chemical tests; identification keys; a review of the ecological role and uses of New England lichens; and conservation status.
