LICHENS

In a 2009 survey, members of the California Lichen Society identified 81 lichen species in Claremont Canyon. Read their report in the History & Research section of this website. Most of the pictures in this album are of specimens collected during that survey. However, species names may have been updated to reflect current nomenclature. Species names used here are taken from the North American Lichen Checklist, Version 20, April 2015: http://www.ndsu.edu/pubweb/~esslinge/chcklst/chcklst7.htm. Viewers wanting more information about lichens may wish to contact the California Lichen Society (CALS): http://www.californialichens.org. Most of the specimens collected by Judith Robertson are now housed in the Herbarium at the University of California, Berkeley. In pictures where a ruler is shown for scale, the subdivisions are in millimeters.
