What is this on my lps?

I have picked it off and it comes back. I see these tubes on some rock but they don’t seem to get any bigger ( I purchased this live rock from the lfs 3 months ago ). This frag is by the live rock that has these tubes. It’s hard to see the tubes on the rock so it can’t be they had I wonder if they are all dead. However I know this is Alive on my corral cuz it grows back.

Btw I know this is hair algae. This is the only spot In the tank that has it. I was hoping my hermits would get to it but they have been ignoring it for about a week. I may do manual removal. The HA is growing on the Skelton of the corral part that died.

That’s what I thought it was. Thank you I will crush the base since this is the only one on a corral. I don’t see it anywhere else in tank.
