Need a quick ID for confirmation

Got this stuff in one spot and not exactly sure what it is…

Don’t want it spreading, and of course on a base rock. It’s green, grass like and just in this spot.

Hair algae?

Hair algae?

It’s a bit more “ robust” with hair algae I’ve dealt with in the past..

Here is another pic. I’m praying it’s not Bryopsis. I don’t notice any feathery tips to it which is why I am questioning it. Also, nothing is touching this stuff. Urchin, snails, tang, Blenny, or crabs. The rest of my rock is barren except this spot.
I’m leaving for 2 months in 48 hrs and that could be devastating if it is. Debating pulling the frag and taking the financial hit. If it is Bryopsis, that could be months of pain if left unchecked for that amount of time. I’ve done this battle before, and lost. Had to reboot the system. This was also when ocean rock was still readily accessible. Not so much now…

It looks contained to the frag plug currently.

Just a comparison on how clean the rest of the rock is..
A few snail shell could get scrubbed I suppose. Second pic next to the chalice frag…
