If I can try to give you a bit of advice, I'd say that you will most likely know mold when you see it. It doesn't look right, sometimes doesn't smell right - certain types harder to see, while some look like cotton or spider webbing.
In other words, if you have come across it, don't smoke it, sell it, etc. Accept your losses, toss it in the shitter and buy more pot. Hope that helps.
