Is it attached to the log under the duff or is it growing from the ground? It looks like it could be a weird morphology of a lobster mushroom (Hypomyces lactifluorum), but I’ve never seen a white lobster mushroom(I’ve been told they do exist though). The Russula Bevipes that becomes the lobster mushroom is white colored. Where was this found?

I would say that’s a Tyromyces (genus)
