White sac under a chalice?

[MauiGatorFan]

I have this white sac under a chalice and I’m not sure what it is. I think It’s too big for a pineapple sponge and looks ominous. And it’s joined by a couple of smaller ones.
Any help? Apologies for the blue pics but it’s pale white. Thanks!

Hard to tell with blue light. White light would be so much better. It looks like a sponge. It's not a pineapple

Ok. Try these.
Thanks!
