Algae or Lichen identification. Coastal BC, Canada
I want to propose you expand your search to a broader taxonomic scope. Specifically, I think you might be looking at a species of &quot;red&quot; green algae (family: Trentepohliaceae).

From Nelson et al. (2011):

All Trentepohliaceae have filamentous growth forms and often contain large amounts of carotenoid pigments (ß-carotene and hematochrome), causing the algae to appear yellow orange in color (Thompson and Wujek 1997, Lo´pez-Bautista et al. 2002).


The Trentepohliaceae contains five genera: (Trentepohlia, Printzina, Phycopeltis, Cephaleuros and Stomatochroon) and 70+ species worldwide.



For example, the following algae (picture from England) looks fairly similar to your specimen:
Trentepohlia aurea

If your specimen is a species in this family of algae, it is most likely in the Trentepohlia genus (or possibly Printzina genus).
Trentepohlia is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae.

Typically orange or yellow in color.
Live on tree trunks and wet rocks or symbiotically in lichens.

Here's a picture of a free-living Trentepohlia species from coastal Oregon, USA:

The source notes that the specimen was simply ID'd as &quot;Trentepohlia sp.&quot; by Tim Rodenkirk (Botanist with the Coos Bay BLM in North Bend, Oregon).
