Taxonomic Comments
Esslinger (2018) transfers Caloplaca ignea to Polycauliona ignea; these represent the same concept for the element.

Rank Reasons
Caloplaca ignea occurs in many localities from northern California to southern Baja California, Mexico, primarily in coastal situations, but also inland (Wetmore and Karnefelt 1998).
Range Extent Comments
"The distribution of Caloplaca ignea seems to be very restricted since all localities are situated in southern California and Baja California, in Mexico" (Arup 1995). C. ignea was found at 18 localities throughout its range (Arup 1995).
Threat Impact Comments
Development and recreational pressures threaten coastal areas of southern California.
Ecology & Habitat

Habitat

Caloplaca ignea occurs mostly on acidic rock. This lichen species has been found growing on volcanic rock, schist, pebble, shale, and granite. C. ignea is not a littoral species, but is better classified as a maritime species. In other words, it is found near the ocean, but not always on the seashore. In most localities this species grows in open sunny areas; however, it does grow in shaded areas. Another lichen, Caloplaca bolacina, is often found with C. ignea (Arup 1995).
