Due to translucence, it was tough to get decent pictures. It seems to form mats(it's the weird looking areas with some brownish tint- filtered items..? in the second picture) with sort of tendrils spreading over the rock. There's a couple tube/spires coming off it also. Kind of looks like a sponge-tunicate hybrid. Have not touched it yet to see if it's slimy/brittle or reacts to touch.. Seems responsive to reef-roids- spot fed the corals a few days ago and it's like whatever this thing suddenly showed up and spread.
