I don't think any of the above so far.
I have a purple stylophora and a spongodes. Attached for reference.
This one only is encrusting, no branching at all, no plating.
Here is another shot of this also, zoomed out. The first pic was through the mesoscope, very up-close.
It is green with brown polyps, but not nearly as green/brown as the spongodes.
To me it looks in the neighborhood of a porites but the polyps are different so I don't think so. Has different polyps than crusting monti I have (also in attached pic).
The coral is really neat, def want to ID it and see if any other colors out there. It grows relatively well.
