sorry my webcam has such lame resolution. the black spots look almost exactly like manure or coffee grindings, they're jet black, made of fine particulate matter.
what the heck is this stuff? is it dangerous enough that i shouldn't even try and save the jars? if the color would come out better, i'd show you guys THE nicest jar os aspirigillus you've ever seen

Looks like Black Pin Mold (either Rhizopus or Mucor), but it could be Black Mold (either Alternaria or Aspergillus), I can't quite tell from your picture alone. Did you pre-soak your grain to ensure the germination of contaminant endospores? If not try it next time as Black Pin Mold often is transmited via the grain itself.
Some strains of Black Pin Mold are quite toxic. Be careful when removing this stuff that you dump it somewhere FAR away from your work space (and obviously NOT in a compost pile), and that you don't touch it with bare skin (just in case you have any open wounds). Don't sniff it either, as some diseases caused by Black Pin are contracted via the lungs. If you reuse the jars, bleach 'em out first, then soak in soap and water overnight.

Yeah be careful with the black molds. They where talking on TV about a black mold that made a bunch of teachers and kids sick atfrom a school.
Never seen a black mold grow on substrate in the year+ i used to culitivate all i ever got was bacteria, the green stuff(bastard contam!), and one time cobweb.

It could indeed be Rhizopus or Mucor mold.
What did you use as a substrate?
If it's rice flour or any other grain-based substrate, I'd say it was Rhizopus.
I did a 3 year science project on using plant extracts to kill Rhizopus Stolonifer (black bread mold). If it was a bit too wet, that's a clear invite for Rhiz. spores; plus they're ubiquitous, so contam by that sort of mold is easy.
If Rhizopus is the case, be careful with it! If it escapes, it can ruin all manner of food in your house. Plus, if you get it in your airways, if your immune system isn't up to snuff and/or your blood sugar is high, you could get something called rhino-cranial mucormycosis. Basically, those spores hatch in your skull. It's not pretty.
I'm sorry you lost your batch. May the spirits of the shrooms shine better on you next time around!
