None of the agar growth is good mushroom mycylium that will lead to a clean transfer, I'm really sorry to inform you that is all contamination. There is nothing there. Stop stop he's already dead :(
I think the actual agar itself may be bacterial based on the look and the other jars that were shot. It has that really opaque and kinda grainy look. Is that just the pics? It may have been incorrectly sterilized or gotten bacterial during the pour or cool down. Usually agar is very "crisp" and transparent. The entire plate even the uncolonized parts look grey and sad like a russian alley or something.
No reason to be sorry, I'm here to learn. I admit, I have a lot of things in motion here and it is all brand new to me. Straight forward feedback is appreciated.
So, the grayish hue is more due to the haze on the inside of the plate resulting from being removed from the 80 deg. spot and into a room that was about 12 degrees cooler. All the plates did that pretty quickly. Here are a couple of more pictures I just took without the temperature change. You can see the actual color and clarity. My recipe was 500 ml water, 7 g agar-agar, 5 g LME (dry), and 5 g potato flakes. The starches from the potato flakes contributed to a cloudiness in the final product. I PC'd at 15 psi for 40 min and poured as soon as I was able to handle it without burning my hands. I did so in my SAB. Fresh out of the PC it wasn't crystal clear. It is still completely possible there are wholes in my technique resulting in contamination. It doesn't look systemic to me but, again, I'm still new to this. All that being said, the results started off strictly bacterial and whatever the white fuzz is didn't start until I was able to stabilize the temps 79-80F.
I'm glad I made the decision to give the BRF jars a shot. My intention was to hedge the bets and so far they are looking good. They are pint jars I've been told to watch for them to stall. They were PC'd for 90 minutes. All I need are a few fruits and I will take an entirely different direction and chuck these plates.
So you really think that mycelium is mold or something else?
