Black Spots on Egg Membrane

[americanchicks]

Hi all and Happy Easter!
Today I boiled the eggs for the deviled eggs Im making for tomorrow. I saw something I have never seen before, black speckling on the membrane lining the egg. The whites of the eggs seem unaffected and the eggs tasted fine. These eggs I have been saving and are almost 2 weeks old. I haven't noticed it on any of the eggs we have been eating recently, but then again havent been looking. Everyone is on a fried egg kick.Has anyone ever seen this?
Thanks

It looks like mold. When you peel off the membrane it comes right off with it.

Saw something about this in the last few months.....
