Taxonomy

C. tuberculosum was originally described as Corallina tuberculosa in 1840 Alexander Postels and Franz Ruprecht. It was reclassified into the genus Calliarthron in 1940 by E. Yale Dawson.^[2]

Distribution and habitat

Calliarthron tuberculosum is found on the west coast of North America, from the Baja California Peninsula to the Alaska Panhandle.^[3][4] It is commonly found in "low intertidal tidepools in moderate to exposed habitats".^[3]

South of Monterey Bay, California, the range of C. tuberculosum overlaps with the range of C. cheilosporioides; as the two species are quite similar, molecular sequencing or detailed measurements are required to distinguish them.^[3]
