They look like a couple of piles of molded fungus at this point. With one picture of each shown it is impossible to identify. Could they be Hens? sure. They might not be either. Bottom one looks more Hen like, top one kind of looks like a spored-out pile of Oyster mushrooms, but Hens are known to grow at the base of Oaks and the top mushroom looks like it is.
Put a gun to my head and I would say the bottom is a Hen, the top is Oysters. 0% confidence.
