Known in CA only from the Smith River and its major tributaries in DNT Co., and from a single disjunct occurrence along the Gualala River in SON Co.; needs field surveys. Populations in decline, with net loss of 12.5% of sites in three-year period. Potentially threatened by air pollution. In northern CA it is usually found on dead twigs, and has been found on Alnus rubra, Calocedrus decurrens, Pseudotsuga menziesii, Quercus garryana, and Rubus spectabilis. In SON Co. it grows on and among dangling mats of Ramalina menziesii and Usnea spp. Similar to Alectoria sarmentosa, A. vancouverensis, and R. menziesii.
