Algae got ne stumped

[Cryptocaryon]

Hey fellow reefers, thanks for looking.

I've been up and down the internet trying to identify this algae. I wonder if any of you guys have come across somthing like this before? It has a very firm hold of the rock and pops like bubble algae when crushed.

did you come across codium?

Not codium. I have codium in one of my tanks and does not look like that. This picture shows what codium looks like. Calcium based type of macro algae.

Cheers,
Alex
