I am not sure of the origin of the stain, however, it is crucial that it is removed. I realize how vicious this is. :(
Thank you for all of your suggestions and assistance!!! : )
Answers:    Brush it near a toothbrush dipped in white vinegar. Let the spot nouns dry, then brush near a sued brush.
Might need to repeat.
Wilson's-a leather jacket store surrounded by most malls- have a really apposite leather cleaner. Just follow the directions
Suede cleaners will usually have a small scrub wad to rough up the suede
Some dry cleaners can do it, but i just don't trust them
