Favid with weird white spot

[Kidnotorius]

Not sure what type of Favid I have, but its defiantly my highlight frag, but today i noticed a small white object growing on it I took three pictures to show it, does anyone know what it is?

It's hard to tell by the pictures but could it be a bit of exposed skeleton?
