Muscadines or Scuppernongs?

So we were out in the front yard and I kept smelling something sweet and familiar. At first I couldn't place it. Then it hit me. Muscadines!
Well I dragged John around to help me locate them and we found a huge mess of them growing in the trees at the end of our drive. So of course I had to pick some. Since I was holding Heidi, John graciously helped pick them. And them stored them in his pants pockets. We gave some to Heidi to put in his pockets but she wouldn't let them go. Then squeezed them to mush. Which of course was fun too.
Anyway, then I started thinking, which is which? Are these muscadines or scuppernongs?
Well in looking up how to spell that, they are in fact muscadines.
Yum-O!
