Rubber residue from previous carpet padding eventually turns black but in some rare cases, it can be mold or mildew from moisture buildup.

Water stains occasionally can also appear black after the carpet has been shampooed. Another reason for the black stuff will be dust accumulation after a long period of time. If you raise the spot and there is a rubbery texture then it’s glue residue but if there is any unsettling smell then it’s probably mold.

Your carpet padding is needed for absorbing and retaining moisture which can also provide a favorable environment for mold to germinate hence the black stuff that appears there. Carpets can also attract grease and dirt easily which is another explanation for it, fortunately, it is a common issue that can be fixed quickly.
