Has anyone everseen discolored yeast in a white labs vial?

Bought this yeast at the LHBS and later noticed a small brownish color in the bottom of the vial. has anyone ever seen anything of this nature? The use through date is April 16th, 2014 so it's still in date and my LBHS keeps in the fridge as I do. Just curious.

I've seen that. I assumed it was caused the way the bottles were stored. Some yeast might have dried out.

I see that fairly often, never had a problem with it. brew on!
