Chunky yeast in primary fermentation??

[beerman123]

I brewed a DIPA yesterday and pitched a healthy 1L starter of WYEAST 1056. Checked on it this morning and the blizzard of yeast activity that I normally see was super chunky with a lot of yeast floating at the too. The krausen looked healthy I just have never seen these chunks of yeast before. I've included pictures. Does anyone know what could be causing this? Infection?

Not yeast, break material...

Cheers!
