More about the book

"Kay Hurley introduces key aspects of lichen biology, environmental roles, emerging uses, scientific history, and myth. She describes the variety of forms that lichens take, from leafy to filamentous to things reminiscent of skin diseases, with imaginative names like witch's hair. She explains the surprising ways that birds and beasts--from reindeer and moose down to tiny tardigrades--use lichens, and how lichens survive in extreme environments, from deserts to Antarctica to outer space. Hurley also introduces some of the innovators who have advanced the knowledge of lichens, from the ancient Greek philosopher Theophrastus to today's professional lichenologists."--
