What is this red algae?

[fohadi16]

Hi all,
This has been growing on my gulf live rock for a while now and I find it very beautiful, however, I'm having a hard time figuring out what species it is. My best guess so far is that it's some sort of Gracilaria but I'm honestly not sure. Any help is appreciated (it's the big bubbly one)

Check out this index of red macros from Gulf of Mexico and you tell us what you have. If it’s fleshy & gelatinous consider Halymenia Elongata. If it’s gelatinous & slippery consider NEMASTOMA. Both are considered highly desirable.

I'd guess that it's some species of nemastoma. This is some of my halymenia:
