Looks like something I've seen before on my own gelding. His hoof did something similar and just had to grow out, but his wall never had that crack in it. Have you tried cleaning it with a soft wire brush or toothbrush to see just how deep the crack goes?
My thinking is that it's just the periople and a little of the outside wall peeling off because it got nicked and that as the hoof grows out that will disappear relatively fast.
