Cal Poly Humboldt Lichenarium

The CPH Lichenarium is a collection of regional lichenized fungi from the Northern California Coastal Range and Klamath Mountains bioregion numbering over 700 specimens. These specimens have been curated by Dr. Steve Sillett, the Kenneth L. Fisher Chair in Redwood Forest Ecology, along with his graduate students. This collection includes a full set of vouchers from a published study in The Bryologist on the epiphytic communities of Sequoia sempervirens completed by Dr. Sillett and Cameron B. Williams. Specimens are available for study by outside researchers and specimen loans. Digitization of the collection has begun as of 2021 with the goal of digitizing the collection entirely over the coming years.
