Red algae id

[FatherDougal]

Can anyone give me an id for this hitch-hiking red macro algae?

It's about 3 inches across, growing in a clump from a piece of rock.

I'm guessing...
Mastophora or Lithoporella, with the conceptacles pretty visible.

Good calcareous alga if so.

I should have mentioned that it is flexible and rubbery as well as slightly translucent. It's definitely a macro algae and not a corraline.

Oh... well then hold on.
The light discolorations had me thinking calcareous.
I'll check some refs when I get home.




While we're at it, not all corallines are non-geniculate.
Some of them look like leafy or twiggy bushes...
like what you imagine 'macro's' to be
