What contam is this?

[thatgreenthumb]

I did an agar transfer from a clean agar plate into 3 sterile WBS/Hpoo/coffee (90/8/2%) jars. This isolate should hopefully drop spores unlike my previous one.

However, a contamination showed its face a few days after inoculation with the agar wedges. This contaminate is fungal but looks to me like an oyster clone i worked with recently. I have no idea how it would have gotten in but here are some pics.





As you can see from the pics. the circled region is growth from the cubensis agar transfer. Whereas the dominant white mycelium outside the circle is a super fast growing contam. It looks amazingly like oyster mycelium.

what do yall think?

Your right that does look like oyster myc. Very agressive.
I once sterilized a jar of rye grain with a filtered lid and placed it in a FC that once housed oyter logs. I was waiting for some other spores. In a few days i was to see a fast growing myc in the jar. It had the tell tale look of oyster. I opened the jar and smelled. If you have ever smelled oyster myc you know it right away.[very pleasant fruity banana odor] I ofcourse used it to spawn some straw which fruited. How the spores got in the jar i dont know.

looks like oyster myc to me too. Wait a few days. If it does not change color you may want to try spawning. But, do it away from your regular grow chamber just in case it turns out to be something different.

thanks for the support
i thought i might be crazy for thinking oyster. but im going to spawn it to newspaper, me thinks to try to get some fruits. im going to wait about a week after full colinization to see if morphology changes at all.

i think its interesting cuz i saw another thread with oysters on poo/coir. unusual substrate but appears to do fine.

So i checked the jar this morning and all the grain is overgrown.
its growing up the glass by more than an inch.
the small circle of intentional growth (cube agar transfer)
is almost entirely grown over by the contam.

If it turns out to be oyster, then im left scratching my head.
Sterilzied grain 15psi 1.5 hr
clean agar plate was used of cubie isolate
transfer was done open air
in a bleach bombed bathroom with bleached and alcoholed tools.
Two jars have contams that look fungal.
the one above and the other may just be cobweb.

the growth just looks too fast to be from spores that got in
the only thing i can think of
would be tissue still in the jar from a previous grow
but i sterelized the crap out those jars.

Im baffled
newspaper will be my selective media to figure this out.
