    Mildew? Mould? Make sure the area is dry, then rub off as much of the blackness as possible with a dry cloth/rag. Then treat the area with diluted bleach (careful with your eyes, since you'll be working overhead). This should shift most of it. Try sticking a coat of paint on....if the stains bleed through, then you need a coat of stain blocker or to paint it with some oil finish to seal in the stain, then paint over it...

    I completely agree with Wertz's advice.

    As well as poor ventilation, I think black marks and flaking on a bathroom ceiling or walls can often occur if it wasn't painted using bathroom paint. So obvious as it sounds, make sure to use bathroom paint!
