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. |
