I’d guess Lactarius

even though there was no latex visible. Not all Lactarius produce milky exudate when cut or damaged. But my tentative identification is based on the stipe features. The very crowded gills, especially near the stipe, should suggest this mushroom is considering a sequestrate habitat as well. While my first impression was Russula, I don’t think the stipe is a good fit.

Cap surface?

Gosh, a photo of the top would be useful
