What is this?

[Reeferman]

I found this black stuff growing on one of my frag plugs. What is this? How bad is it? And how do I get rid of it before it spreads?

Black sponge. I hear it stings. I have some & brush it off where I don't want it to grow.

Thanks for the help. I definitely don't want it to swallow any more of my corals.
