Toadstool or Mushroom?

For the latest iteration of Cee’s Black & White Photo Challenge – It’s All About Nature – I’ve chosen this toadstool (or is it a mushroom?) that I found growing by the side of the road near Chansigaud. In real life, it’s a creamy colour, but the monochrome brings out the texture (note especially the jagged edges) very well, I think.
