are you sure its mold and not krausen? Now long has it been fermenting? I know with mead you would just be able to clean it up and it would be ok (although this has not happened to me yet). I read this on another forum. I read though that in the case of beer is should be ok as well. I read this in John Palmer book, I believe

defiantly not krausen, it's been sitting in secondary for about 3 weeks.

Hmm somethings going on then. Have you checked the gravity? If its high it could mean a stuck ferment. Alcohol should kill off any most once the yeast starts to eat the sugar. If there is a large yeast cake on the bottom then quite likely its done, in which case Im not really sure about the mold problem here. Also wait for other more experienced brewers chime in. Id be interested to see other comments as well

gravity was 1.020 when I transferred to secondary. and it's likely dropped a bit since.

Without pictures it's not really easy to tell. There are approximately 10 trillion threads on here where people were convinced their beer was contaminated, and it ended up being fine. If we can see it, we can help.

Yeah - it could very likely be "yeast rafts" - little tiny clumps of floating yeast that makes the surface of the beer look like a petri dish, but are totally harmless. Post a pic and maybe we can tell.

Look closely, the spots are likely clumps of very small bubbles. The bubbles are CO2 that are much more apparent in darker or black beers. Gently rock the carboy and see if the clumps break up. If so you have bubbles.

I have had several batches look like mold in the secondary and i have never had any problems with that beer, the yeast can somtimes look like mold. all you can do now is proceed with bottling or kegging and see what happens.
