Acknowledgments

The checklist and content of this website are based on John W. Thomson's The Lichens of Wisconsin. His work as well as the work of his students has contributed tremendously to the knowledge of lichens in Wisconsin and to lichenology in general. We are grateful to Dr. Thomson and fortunate to be able to make lichens more accessible through this website.

We thank the Botanical Club of Wisconsin and the Herbarium of the University of Wisconsin - Madison for supporting the development of this website. We acknowledge the Department of Botany and the Herbarium of the University of Wisconsin - Madison for providing the computer facilities and ongoing support necessary to carry out this project.

Without the computer expertise and creativity of Merel Black and Glen Berry, this website would not have been possible. We would like to thank Paul Berry and Lois Brako for logistical support, comments, and suggestions. For helpful suggestions we also wish to thank James P. Bennett (Biological Resources Division, U.S. Geological Survey and Institute for Environmental Studies, University of Wisconsin - Madison), Martha Makholm (Wisconsin Department of Natural Resources), and Susan Will-Wolf (University of Wisconsin - Madison).
