These are Milk Mushrooms, Genus Lactarius, I can't tell which ones from these pictures, one specimen looks quite old though. These mushrooms are not active, but are edible after a treatment. Quite tasty too. I got a whole bucket of Lactarius the other day, you have to put them in water for about 2-3 days, then drain the water out and marinate them. They are naturaly quite spicy, the water treatment helps you get rid of the strong taste. Id them first.
