Mold?

[abciximab]

I have a Pilsner fermenting and noticed this black material in the stopper, and the krausen was more green than I’m used to. There’s no other sign of infection (pellicle) and it smells generally fine. Thoughts?

Certainly don't want mold in any parts. I do believe it's best to throw away the stopper with mold and get a new one.

IMO, the green stuff in the fermenter are hops rising during fermentation.
