Why does black mold grow around and inside a gas cap lid? Is it a Southern thing? Did I fail Chemistry 101?

I went and researched it. The mold is commonly found around anything that uses ethanol. So, that's why your gas cans turn moldy, and your infrequently washed vehicles get black mold around the gas cap! Why this happens I don't know, but it's associated with ethanol.
In reply to Shavarsh :
Aha! Same stuff! it's named Baudoinia compniacensis and it feeds off the sugars. Thanks!
I bet it's compounded by a leaky gas cap.
