OOPS, Daniel
I hope your cultures don't have a good lawyer!
Maybe the explanation is that the media we were were using here was so 
bad that the N.crassa just HAD TO GET OUT. Or maybe the visiting worker 
didn't bring N.crassa with him, just a lot of mites.
Look forward to the beer. Come and try the stuff I brew !
