COBWEB in rye jars?... Confirm/Deny?!
    #13033142 - 08/10/10 06:29 PM (14 years, 5 months ago)

I know cobweb mold is supposed to be very rare in jars..... but I think I have it in ALL 6 of my quart jars I recently knocked up.

I'm 90% sure it is cobweb mold... the only reason I'm hesitant to toss them is because it's been 3 days since I saw the first growth, and they haven't completely colonized the jars. I know cobweb is supposed to be really fast, like taking over in a day or two.
But it definitely LOOKS like cobweb in all of my jars.

I inoculated all of them last week... with two different MS syringes I made from the same print.
They were fine for the first 3 days, then they started to show a little wispy white growth.. right where I inoculated...
At first I thought it was just weak mycelium. But then it grew more and more... and the more it grows the more I think it is NOT mycelium... it certainly doesn't smell like it...
A quick whiff of the jars from outside the filter reveals a funky, almost sour but not quite... subdued moldy smell. Not like a sour bacteria smell, but not like a fungusy mushroomy smell either.

Here's some pics... I had to open a jar to get a good shot of it.



That's cobweb.. right? I've never seen mycelium that looks like that. It's been a while since I've grown so I have to make sure..
If so... how the hell did it infect ALL my jars.. and no mycelium grows? must have been a contam print?

Cobweb?? Confirm/Deny??

its definitely not mycelium, they're toast

im not positive its cobweb; ive never myself seen it in a jar, usually only on casings where it tends to grow very very fast, and very fuzzy, greyish in color, not quite as dense as in your photos, but again it might look more dense in the environment of a jar, coz the the second photo especially, looks quite like it may be

It's mold. Exactly 'what' mold would take DNA analysis.  Toss it.  I'd suggest pouring some petri dishes to isolate the healthy mycelium on that print away from the mold.
