Caps of southern clam shell polypore mushrooms ...

The image shows two large caps of Southern Clam Shell Polypores mushrooms growing on the side of a log. The caps have a flat top and are slightly curved downwards at the edges. They are covered with thick, grayish-brown scales or scurfs that resemble old clam shells. The surface of the cap is also covered in cracks.

The mushroom caps appear to be overlapping each other, as if they are growing on top of one another.

The background of the image is a blurry view of the log's bark and possibly some moss or lichen growing on it. The overall atmosphere suggests that the mushrooms have been growing for some time, likely in a moist and humid environment such as a forest or woodland area. – AI vision
