No specimen available

I have seen these mushrooms in my yard for several years, this happens in the fall. They grow around oak stumps and are gray with smooth caps that are dented in the middle. Very dense clusters of irregular shapes. They are first noticed as white lumpy dense bulges that look like they might be giant puff balls. The gray mushrooms come out of those lumps.
The stipes are white and the gills curve onto the top 1/4 inch of the stipe. Gills are course and dry with no latex.
If you skype me I can show you one.

Thanks, Mike

Yes, looks like a parasite

I think I can see a brown Armillaria in the second photo. It is parasitizing the grayish Entoloma making infected fruit bodies look like a shapeless white mass.

Thanks for the quick responses. I see fungus on a fungus, is the gray mushroom a parasite on the white mass?
