Can one corals death cause a chain reaction?

Are they getting stung from the mushrooms?

That sounds like a more likely culprit. I've had mushrooms take out multiple colonies in hours.

I've had mushrooms sting colonies, they die where they were stung, but I've never had a colony die because of that. Can that happen?

I dunno, this looks too much like a proximity thing from the images, the dead coral in the middle, and the bleaching spreading out from a central point centred on the dead coral. Is it possible that this was the end result of a very aggressive case of allelopathic warfare?

Some of my sps colonies are bordered by mushrooms and/or ricordia and none of the sps are stressed either. The surface of the coral dies where the shrooms meets, but then the sps will start to grow around and over the shrooms. It creates a nice natural border. My vote is for another stressor!
