Chicken-type fungus, home

This has not been, so far, a notable autumn for mushrooms, and you can blame that paucity on the drought. Fungi, of course, delight in rain, but some manage to find moisture in other places. This one, a kind of Polypore, or, perhaps as it's better known, a Shelf Mushroom, gets its liquid diet, nutrients included, by tapping the circulatory system of an oak tree. As I'm commonly lamenting, I need to get better at ID'ing fungi, so all I can say for certain is that I doubt it's what I thought it was at first glance: a Chicken of the Woods mushroom... and one of the best eating varieties. Instead, my suspicions and my Audubon Field Guide are pointing me in the direction of a Black-staining Polypore. It's also edible—I'm told it tastes like beef liver, which I enjoy—so when it gets light again, I'm going to have to see if the flesh bruises black.
