Nephroma helveticum subsp. sipeanum
Dark brown to black thallus, with some white to black underside. Reddish brown apothecia with white apothecia rims. All members of this genus contain Nostoc sp. (Star Jelly is a Nostoc sp.) as the photobiont, and some species also contain green algae. I have only seen this species on sticks from recent windfall, so I suspect they grow higher up in the trees.
On Sitka Spruce twigs that fell on the ground.

Well done. A very attractive species.
Thanks Mark for your suggestion! After getting an ID on this, I read that this genus is often mixed up with Peltigera, but I think the formation of the apothecia in this genus helps distinguish it from Peltigera as well as a few other subtle factors.

Fabulous colors. Maybe it's a young dog-lichen like Peltigera horizontalis?
