The mycological collection at the Santa Barbara Botanic Garden comprises a small but growing set of specimens focused on representing the diversity of macrofungi from the California Channel Islands. This collection complements the lichen (53,000 specimens), bryophyte (731 specimens), and vascular plant (160,000 specimens) holdings at the Garden, which are among the world's best representations of the plant biodiversity of California's Channel Islands, as well as the broader Central Coast region.
