American lager mash kit. Looks awful

[pk]

Hi,
Tried to brew this yesterday, I had to shorten the final boil from 90 mins to 60 mins. I've never made a lager before so wasn't really aware that fermentation had to be at 10 degrees.

I left the fermentation bucket out in the garage last night, today the wort looks like there is mould on top, it's like there is lumps of cotton wool floating just beneath the surface or something.

The yeast was a powdered thing from a sachet. Is this normal for lager?

If you just sprinkle dried yeast on top then they slowly re-hydrate and start working. Sometimes you can watch clumps of yeast rising and falling through the beer or wine.

Relax!

You just pitched many billions of yeast cells 

A single or 100 "infection cells" could not possible multiply that quickly. Infections can take weeks to become a problem.

As CH says: A pic is worth a thousand speculations! For this post there are 999 left
