what is this worm? Parasite?

If you've ever fragged mushrooms, you'll see that these are just shroom guts. The fact that the shroom is extruding them makes me think that the underside of the shroom was abraded. Have you recently pressed on the shroom? maybe when you moved it?

I recently got them from noirsphynx (lovely tanks, and their clownfish are breeding) so they got moved around when I placed them into the tank, and probably slid around in the transport bag a bit. Not to mention a 4hr trip home...
How good are the chances of them surviving? I did move them into the shade and they seem much happier already, opening the cap instead of it being all shriveled. The one that was in shade from the beginning is already splitting.
