Family Polyporaceae
violet-toothed polypore

very young Violet-toothed Polypore, Ohio, July 2008
This is a polypore fungus, but it also grows teeth on the undersurface, making it look like a toothed fungus. It changes appearance quite a bit as it ages, becoming darker, then fading to white. Taxonomy unsettled, may also be listed as Trichaptum biforme, or Polyporus biformis, or Polyporus pergamenus, or Trichaptum pargamenum, or Hirschioporus pergamenus
