Is this a white truffle? What mushroom is it?
Your pictures do look like a truffle from the outside. If it is a truffle, it would have a truffle strong smell. It would be solid. When cut open, the fruiting body would have a network of spore producing channels, looking somewhat like a maze.
I would not recommend eating until you have someone else look at it in person, and determine the characteristics I have listed.
