Those white ones look like peppery lactarius aka Lactarius piperatus. And guess what they are edible and easy to figure out. Just take a tiny taste test and if it burns the heck out of your tongue its a piperatus. Or if you want to take a step before the nibble test just cut the gills and if milk comes out its at least in the lactarius family and not deadly poisonous. I usually dry these and use the powder as a spice, it tastes just like black pepper.
