How to remove mould from wallpaper?

At the rear of the house, we have French doors with a window both sides - almost to the corner.
Have full length curtains, that is just a couple of inches from the floor.
Just noticed, what I can only describe as spots of black (or near black) mould on the top of the skirting board a few inches both sides of the corner. Moreover traces of it going up the wallpaper in the corner.
The right hand side looks okay, its just the left. Initially was a bit concerned it may be connected to problems with the kitchen on the other side of the wall (that was 'tanked' etc). But no, fortunately, the wall does not feel cold, think it more a case of poor air circulation.

Question is - how get the mould stains off the wallpaper??
They came off easily enough, from the skirting board.

You could try squrting it with mold spray ( e.g. Astonish brand.) Make sure floor is covered with an old towel; curtains, furnishings are kept well clear.
Do a spot test first. Allow the spray to work. It might take half an hour to see any difference.
I do this around my patio window.

Can you ventilate the area better?

Try using Fungicidal wash

Microfibre clothes can be useful on mould. You will need to be careful how much pressure you apply. I would also recommend using the minimum of water or other liquid cleaners on wallpaper.
