Lepiota aspera / L. acutesquamosa might be a good candidate name for this.
Look at the spores and the cells on the lamella edge – they should be relatively slender and balloon-shaped, resp.

but appears to be one of those species trying to become a truffle. With a white spore print (surprise!), Amanita is always a front-runner. However, the gills seem to be crowded and growing together, or fusing. There is an extensive covering of some of the gills (part of the annulus? or is it something else?). I don’t know enough about the hypogeous (usually) relatives of Amanita and Macrolepiota to be sure of what this is. But it is interesting!
