It doesn’t look like other Callophyllis on this app, but scroll down to the very bottom of this page and look at the second to last species: https://www.centralcoastbiodiversity.org/red-seaweeds.html
Anyone have any other ideas?
Also looks like it may be reproductive? (See my second photo)
More of a coral-pink colour, though my camera couldn't capture it. Potentially UV reactive.
This seaweed clings to rocks and is called Sea Moss or Nail Brush Seaweed.
Very small - about 4" long. In ice on driftwood after storms and King Tides.
