The California Lichen Society seeks to promote the appreciation, conservation, and study of the lichens. The focus of the Society is on California, but its interests include the entire western part of the continent.

The Bulletin of the California Lichen Society, which is published twice a year, welcomes manuscripts on technical topics in lichenology relating to western North America and on conservation of lichens, as well as news of lichenologists and their activities. Technical articles are peer-reviewed. Back issues are on line.
