Lichens are everywhere, yet most people fail to notice them because they are so familiar. The story in this chapter was written to help persuade teachers to acquaint their students with these unique forms of life. Many biology teachers tend to gloss over the study of lichens and many of the other simple plants, even though lichens are universally available in virtually every environment, including urban centers. The author hopes that this story will help more students appreciate and become interested in lichens. This free selection also includes the Table of Contents, Preface, Introduction, and Index.
