Possible contamination

Hi, about 3 weeks ago I cased one of my grain jar with vermiculite/peat moss and, so far, I haven't see any sign of grow on the surface...
How could it be? if this was a contamination wouldn't there be something visible?
Does this happen or should I throw my casing away?
Thanks

Did the grain jar smell like fresh mushrooms? If you're casing the top of the jar to fruit that way, don't go over about 1/4" casing depth. RR

After a month it started to have a strange smell so I disposed of it... I recently made two other casings, could you tell me if they look fine?
This one look fine to me :

I'm not sure about this one, the mycelium seem darker, do you think it's cobweb or i am paranoiac?
Thanks for your help

Looks like mold to me,mycelium should be white. The top looks fine so far,the bottom one looks a little off.

The bottom pic is fine. DON'T spray peroxide on it. It doesn't look anything like cobweb. RR

It was a lot prettier in the first picture. Cobweb is very whispy and grey. It's often compared to an old ladies hair. It should recover OK. If it had been cobweb, you would want to spray it with 3% peroxide right out of the bottle, and it would have melted on contact. RR
