Sometimes I notice a spot like that on the odd cigar...mostly it seems just below the surface. That particular stick was recently puchased from a well known internet company and was delivered to me in FLorida. I am quite sure the cigar is fine and it won't affect the taste at all. I would like to tell you more about the cigar to re-assure you, but I would hate to give you an unfair advantage
Seriously though, I am sure it is fine and anyways it would be a waste to throw out a $15 cigar ooops! Did I say $15 sorry, I can be such a liar sometimes, but not always...only if I am telling the truth while lying about it.
