These orange and yellow mushroom brackets are growing on a dead tree in the woods at Mountain Lake Conservancy in Virginia. Also called sulphur shelf because of the color, this mushroom does not have gills. It is a polypore mushroom. As you can see from the photos, the fungus can produce very large numbers of fruiting bodies, which are edible when young (if you are not allergic to it!). So, what does it taste like? Chicken!
Look for Chicken of the Woods fruiting anytime between spring and fall. They are commonly found on oaks.
