this contam resembles mycelium that
colonizes a jar really quickly.

it appears very 'smooth'

when birthed
the contam has a very rubbery texture
and is usually un-colonized in the middle of the cake.

after maturing the contam
forms what looks like invitro fruits
with a slightly tan appearance.

i was fooled by it a few times
thinking they were ultra fast jars.
so i started referring to it as fools mycelium

anyone know what contam this is?
thanks:)

Geez Mycobri, That's weird. I had something similar happen a year ago but it took hold after the jar put out it's 3rd flush. It had the same color and rubbery texture you describe. It was not as widespread, maybe the cake was kind of dry or was running low on nutrients. Like you said, looked like tan invitro fruits. I din't know if they were just smooshed up mutants, but as soon as I felt them, I realized that's no mushroom! Anybody else have something like this?

Dont know, I see it in a few jars every now and then.
When i go to case, i just leave that part out and save it for outside, some will fruit later out there.

It looks as if a polypore has contaminated your substrate. I've had numerous run ins with polypores lately and all of them show that rubbery mycelium prior to fruiting. I think it's deformed primordia because of the high levels of co2.

Fruit it, as i'd be willing to bet that's the problem.
