Need coral identification please

[Lwaynebowen1975]

Sorry if in wrong place but didn’t know what this coral is? The guy I bought it from said he couldn’t remember either. It is a very small piece so hope you can see it. Thanks so much for your help

Looks like a mushroom to me.
But the picture could just be blurry
