Is my beer infected

My IPA was in the primary for 2 weeks, I racked it and dry hopped about a week ago. I checked on it and it has tan chunky stuff floating on the top. They are about a 1/2 inch think or so. Any idea?!!!

sounds like some floating krausen. how does it smell/taste??

pictures?

Krausen or yeast clumping.

Sight is not the best way to tell if a beer has turned bad. Smell and taste are much better.
