Known in CA only from Jedediah Smith Redwoods SP. Historically threatened by logging. Possibly threatened by alteration of fire regimes. Host conifers could include Abies grandis, Pseudotsuga menziesii, Sequoia sempervirens, and Thuja plicata. Similar to C. lenticulare; however, C. adspersum is the only species of Calicium currently known from the Pacific Coast with a yellow pruina. See Bulletin of the California Lichen Society 13(2):51-54 (2006) for CALS Conservation Committee sponsorship.
