I don't want to say yes or no as I have no idea where the bud came from. Still a little hard to tell from the pic.
I've had perfectly fine bud that looked similar, usually where a stem broke off. (If you're referring to that little white spot)
Mold is usually like a foreign thing... you can tell it's there. Like when bread or fruit gets mold, and it "Grows" over the fruit like a white cloud. It will also have a distinct musky, wet, damp smell to it.
