Here is an article from Cigar Journal. White mold is no question mold and you will see pictures of it but it's harmless.

Stalks like in the picture are efflorescence IMHO
Cigar Journal did an article on it and they reference it in the link above but you have to pay for it now unfortunately and it's that article that converted me to dissenter status.
I will buy it later this weekend because it's so topical to this hobby and the topic always comes up.
