there's 30,000 types of mold... for anybody to tell you what it is would be guessing. 
they'd also be guessing if they told you where you went wrong. it could be:
1. improper preperation/sterilization of the jars in the first place. 2. contaminates you introduced through inoculation 3. contaminated syringe (probably least likely if you got it from a vendor, they do prepare syringes with pro grade equipment for a living after all, and you've said you're new to growing.)
next time around, leave one jar un-inoculated. pretend like you're inoculating it, do everything but stick a syringe in it - treat it like the others. sterilize it, cover it the same way you cover the others, incubate it. that will help you figure out if your problem was #1 or #2. if it contams even though you didn't inoculate, your problem is #1. if others contam, but your control jar doesn't, well then you need to look at #2. trying to figure it out now without a control like that would just be guessing... unless you made an obvious screw-up you're not telling us about. 
the only way to know about #3 for certain, would perhaps be to view the solution under a good microscope with an experienced and knowledgable eye (which probably is out of the question here), or barring that, inoculating agar plates that have been prepared in a proper sterile environment (glove box or flowhood) with the syringe, and again using a control plate or two to be sure you didn't screw up steriliztaion... which again is probably beyond your means at this point in the game... so you'll have to trust me when i say its probably not #3.

I would suggest you review this for a POSSIBLE mold ID. http://www.shroomery.org/index.php/par/23418
