some before and after photos:

This one was taken the day after I introduced the colony to my tank. I
spent about 45 minutes doing a slow drip acclimation and the polyps
extended out within 3-4 hours of placement in the tank.

This was taken tonight. The white area first appeared yesterday morning,
so whatever this is, it's moving fast.

Those look to me like a problem with to much light. It could be that
they have been aclimated to a much lower light level than you have an
the brighter light is causing to much oxygen to be produced in the
tissues. I can't remember what the term is for this but try shading the
shrooms and see if the problem goes away.
