Dry cracked cake on top of primary

[bjoernbernes]

Hello

APA after 16 days of primary at 15-17 degrees celcius with (W44 US West Coast yeast) we met this sight (see picture). A big dry craked cake on top of our fermenting bucket. We have brewed this APA many times before but never seen this. What is it? And how did it happen?

Your picture didn't come through. Sounds like a pellicle from the description though.

Actually that doesn't really look like a pellicle, just a bunch of yeast floating to the top.
