First Time Grower Seeking Cobweb/Mycelium Determination

First, hello all! I have lurked for a while but this is my first post, w00t!
I recently began my first grow with P. cubensis B+ from EDIT: newb mistakes, whoops [/edit] and almost immediately I saw what I thought was cobweb mold so I threw them in the PC and pulled up the shroomery while I watched by the stove.
Here are a few pictures:

All of a sudden I had some doubts as to whether that 'cotton-ball' looking stuff was really contamination or if it was mycellium! The photos are post-PC, and immediately afterwards I dumped the contents of the 5 jars.
Moot point by this time, but was I too quick to give up on my mushrooms?
Bonus question: I will be asking later in cultivation, but the inoculation point on my jar lids are protected by a wad of poly-fill covered by several strips of waterproof medical tape. The tape doesn't take well to the PC. It tends to get wet and fall off. I thought a layer of tin foil would prevent this but no dice so far. Any tips? Is the poly-fill + tape insufficient?
Thanks bunches!
EDIT: Obviously not cobweb from what I have read recently, but most likely a nasty. At least I did the right thing.

Being a fairly new mycologist myself please don't only take my opinion into account. That being said unfortunately it does look like your substrates were contaminated with some type of cobweb mold. From what I understand whenever you see that wispy unconnected stringy (that almost looks like individual threads) type of growth it typically is an indication of cobweb mold. As to your inoculation, I think your polyfill method should be sufficient in keeping contams out, more likely than not the contam came from the needle itself or the syringe that they came in because almost all of your substrates seem to be fairly contaminated. Best of luck to you on your future grows.

Cubensis mycelium, in my experience, coats the birdseed and looks very different than what I see in your picture. Are you soaking your birdseed? I've heard that endospores can survive the pressure cook if you're seed isn't prepared properly.

Yes my birdseed was soaked for 48 hours. I don't really buy the whole rational behind soaking but I did so anyway. The autoclaving conditions were set as the conditions at which endospores of a safe majority of contaminants will perish. It makes sense that the soaking would reduce endospore numbers, which is important, but only PCing at proper conditions will make the jars "sterile."
I rushed through the inoculation and I likely got contaminated there. This is the reason I so quickly assumed that the growth was a nasty instead of mycellium and dumped the batch. From now on I will try to exercise more patience.
Does anyone else have any opinions on the above photos? Like I wrote before, it doesn't matter at this point but I am curious.
