I had something like this happen to a batch of whiskey once. Was always under the impression that white mould isn't particularly dangerous, so I just scraped off the stuff on top and then dumped another batch of yeast on top. It seemed to fire up and fermentation completed. Once I ran it I ditched the contents of the fermenter, but at least it wasn't a total waste, and the taste of the booze never suffered. Weirdest thing was that I had made 2 washes exactly the same way and at the same time - one had this white mould infection but the other was fine.
