Stereum complicatum/Stereum hirsutum Group on an Abnormal Substrate

Jason and I were outside tidying up around the camper, and I heard him calling my name from beside our shipping/storage container. He found these fruiting bodies growing on a nylon rope. They were disturbed/broken a bit because he didn't realize they were there initially. There was no wood in the immediate vicinity (just soil/dirt), so we thought it was pretty interesting!
