WTF are these black spots on the wrapping on my rockwool cubes that look like spores?

Two images are what the black spots look like under a microscope and the other is what they look like to the naked eye.

WHY THE FUCK DOES GRODAN WRAP THEIR GOD DAMN ROCKWOOL CUBES IN SOMETHING THAT HARBORS AND IS CONDUCIVE TO FUCKING MOLD GROWTH?!@

I took off all the wraps and put the UV-C light-based fan-pumped filter near the cubes but I really am upset that this shit is showing up in the first place. WTF kind of spore is it and should I be even more concerned about it? These cubes haven't even been in the tray for two weeks and barely watered more than once and this shit is showing up.

grodan does not put fungicide in their product don't know what gave you the impression they would

I didn't assume they put fungicide on anything, it's the presence of the paper and glue that seems to be what is so friendly to spores.

dude I didn't have any fuckign problems with that shit. .just slide off the plastic and use the squares lol. not a big deal man.. not a big deal AT ALL/.

Exactly, just remove the wrapping.
Or don't. I don't take the wrapper off, and I get that black stuff too, but it doesn't seem to have a negative effect on anything.

i've been growing that black stuff since i started using rw, they seem to be my roots gaurdians and protect them against something else that lurks.

And it looks just like what you see in my pictures? Does it always seem to show up on the paper wrapping near the bottom or in other places too? It seems pretty threatening under a microscope.
