Genera Lichenum

Genera Lichenum: An Arrangement Of The North American Lichens is a book written by Edward Tuckerman in 1872. The book is a comprehensive guide to the classification and identification of lichens found in North America. Lichens are a symbiotic organism composed of a fungus and an alga or cyanobacterium. They are important indicators of environmental health and are used in a variety of fields, including medicine, ecology, and industry. The book begins with an introduction to the history and classification of lichens, followed by a detailed description of the morphology and anatomy of lichens. Tuckerman then provides a classification system for lichens based on their physical characteristics, including color, texture, and growth form. The book includes detailed descriptions of over 500 lichen species, including their distribution, habitat, and ecological significance. Genera Lichenum is considered a seminal work in the field of lichenology and is still widely referenced today. Tuckerman's classification system has been modified and expanded upon over the years, but his work remains an important foundation for the study of lichens. The book is a valuable resource for botanists, ecologists, and anyone interested in the natural world.With A Memoir Of The Author.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
