Lichen Field Guide for Oklahoma and Surrounding States provides descriptions of over 120 lichen species, using characteristics that are easy to learn and observe in the field. It suggests additional chemical tests that can be used to differentiate between similar species. It is hoped that this field guide will promote the study of lichens for academics, government officials, and amateurs.
