frogspawn growth?

Can anyone identify what this white portion is? Is it new skeletal growth?

Can you draw an arrow on the photo?

Are you referring to the healthy tissue that extends onto the skeleton?

Yes. I do not remember it being there the last time it retracted.

My guess would be new growth. But not down onto the old skeleton, the polyp is growing new skeleton and tissue is also growing making the "skirt" around the base of the polyp longer.
