Mushroom growing on dead redwood log.
Growing on fallen twig.
After some discussion with a mushroom group on FB I decided this must be aurantia instead of mesenterica sp because of the presence of the host fungus-Stereum hirsutum which it is known to parasitize.

Tremella is a genus of fungi in the family Tremellaceae. All Tremella species are parasites of other fungi and most produce anamorphic yeast states. Basidiocarps (fruit bodies), when produced, are gelatinous and are colloquially classed among the "jelly fungi". Over 100 species of Tremella are currently recognized worldwide. Two species, Tremella fuciformis and Tremella aurantialba, are commercially cultivated for food.
