have you seen this turf algae before?

Is it biopsys? It is extremely hard to pull out, the rock will almost lift up and the LR will loose a few chucks with it.. or whatever it is, it seems to trap detritus to sustain itself with a strong substrate hold.

Thanks.

go to melevs photo sheet and you will find it there, i really looks like bryopsis, bry also looks like hair algae.
