Plant id/spot the blenny

But mainly plant id... It's been growing with seemingly increasing speed over the past few months and Internet searching isn't finding me an answer. Any ideas?
Kinda looks like a type of caulipara. Probably misspelled that. A macro algae that some people use in refugiums.
It's kinda unique because it's brown, so it's not a caupluara (sp?) but I'm not sure what it might be. You can check out and see if they are selling something that looks similar to it.
