Petrified Mushroom is one of the five plant fossil displays found on the Paleontology floor of the Varrock Museum. It’s made by adding a fossilised root, stump, branch, leaf, and mushroom to a plant display case.
When seaking with David about the display, it becomes apparent that he doesn't know anything about it (or anything else in the wing). He'll either tell you that it "appears to be thousands of years old," or that he knows a lot about the fossil, but "can't share the information right now."
