You beat me to it, but I'd have a word with Judy first I think you need talking through it first, I had an enquiry about this last year and although I didn't do it you may want to get some real 'pro' advice before you apply and go.

Hi Eric
Mold/mould on leather causes a particular set of problems that needs to be addressed.  'Cleaning' a mold problem (just with a leather cleaner) will only clean off what you see on the surface and wil lnot kill the mold to prevent it from returning.  To do this you need to use an enzyme cleaner or a mold killer.  As far as we are aware the only products that have been tested on leather (over a number of years) and will not damage the finish are Em Clean and Mold Killer.
You do not state what you have used to clean the leather so I do not know how successful it will have been at removing all the surface residues.  Mold that has been left on leather for any period of time can also cause damage to the finish which is maybe what you can now see (this is often like a pitting effect).  If this is the case the only remedy would be to recolour the area once the mold has been eradicated.
Mold Killer as mentioned above is a stronger product than Em Clean for really stubborn cases.  It is slightly more complicated to use and on finished leather (which I am assuming this is) we have had more success (and easier results) with Em Clean
