ID on a bubble coral

[Costareefer]

hello friends. I have this bubble coral that I can’t decide if it’s physogyra Lichtensteini or plerogya sinuosa. The “bubble” on this coral is irregular suggesting physogyra but the shape and size of the “bubbles” indicate plerogyra. Here a couple pics

Pleogyra or "classic bubble" corals have bubbles ~1 cm in diameter, physogyra or "pearl bubble" have much smaller bubbles, judging on its apparent size comparedto those clove polyps leads me to believe you have a pleogyra .

Can we see it closed up? Plerogyra is flabello-meandroid while Physogyra is meandroid.
