YELLOW SPOTS = something other than mushroom mycelium.
 
These are LC to wbs jars at about day 7. Other than WHITE MYCELIUM, the only other coloration remaining, is from the seed color. Which, will become WHITE, in a day or 2.
Again, Myc Piss is an excretion of some excess metabolite. Usually, from manure, or excess nitrogen.
Whatever is YELLOW in your jars, is not Myc Piss.
Aspergillus flavus is YELLOW SADLY, that is what appears to be contaminating your jars.

At least, toss the content. The jars, you can recycle. Fill a tote with hot water, and sudsy bleach/Lysol. Hold jars underwater, unscrew the cap, allow jar to fill, screw cap tight. Later, take outside, dump content in dumpster.Run the jars through the dishwasher.
Or, if not conserned about the jars, toss them - unopened.

Of course it can spread if that's even what it is. You've been advised to toss it out, as one should do with all contaminated projects. RR

Contams spread, it's what they do.
I doubt the supposed Aspergillus flavus is going to appear and isolate itself to a couple dime spots.
Things grow, ie spread.

I've seen some pretty bright yellow myc piss. Sometimes it's yellowish-brownish. Other times it's pure yellowish.
That pic is totally fucked. That bright neon yellow is totally unnatural, so it's really hard to tell.
To me it looks fully colonized and the yellow is just on the surface of the myc where it's against the jar. No way to tell unless you examine it and describe it better for us.
I wouldn't throw it out. Examine it closely when you case and determine if it's myc, spores, or just liquid. If it's the actual myc color or spores then throw it out.
Otherwise I stand by my diagnosis of mycopissosis. Be sure to report back.

Mycelium excrete excess metabolites. Usually, excess nitrogen. Grains, and WBS do not contain that much nitrogen. At least, not so much it would be excreted. Whatever it is ? It certainly appears to be mycelium of some sort. Certainly not mushroom mycelium. Otherwise, you would see that yellow in everyones grain spawn jars.

Rye jars often get myc piss if you let them go too long or incubate at too high of a temp.
They can produce a LOT of myc piss if you let them.
> Otherwise, you would see that yellow in everyones grain spawn jars.
If you incubate too long or at too high of a temp, you will almost certainly get myc piss IME.
We'll just have to wait and see what the report is. Those jars are ready to go! Dump them carefully and examine those spots closely so we can figure out what it is. My bet is on myc piss. I think his camera just made the yellow look neon yellow.

It's most certainly a bacterial contamination if they were sitting around for three weeks before you re-inoculated them... Remember, letting uncolonizing jars sit around gives even the SMALLEST, WEAKEST spores and endospores a chance to gain ground. That said, your mycellium colonized the jar and took up the space, but the bacteria pressed up against the glass just waiting for its chance.
As far as myc piss goes: It could be a bacterial contamination with metabolites surrounding it, I've seen myc excrete metabolites to quarantine a contam before... That could add to its nice yellow hue.
Anyways, if you're comfortable getting possibly quite sick eating mushrooms, then go ahead, fruit the jar. If you value your health, then throw it away, because it's definately a crapshoot.

I'm an amateur but my loot is on contam. I've never seen piss like that. It's too bright and too acute.
But to reiterate, I could definitely be wrong here.

Could make you sick or very sick, it's your choice.... could also come out entirely fine.
just remember, if you die, it's not because of the people here telling you should eat the shrooms off a contaminated cake.
Ultimately, the decision is yours. I understand that it takes a long time to get a cake completely colonized, but I think it's worth it to get it right once in a while... If that means ditching right before it's birthed... that's what I have to do. If you don't ditch, your health is in your hands. That bacteria can get onto the mushroom, even though it fruits normallly, and it can make you sick.

> so if this cake flushes as a normal cake would....you think its gunna kill me?
No. Anything that landed in your jar and grew is something that's in the environment all around you all the time. It's possible that it's a dangerous contam, but highly, highly unlikely. Eating mushrooms from a casing made with it would be no more dangerous than eating a piece of bread that had a spot of mold on it.
For all the nay-sayers and fearmongers that like to try and scare people I've never seen any reliable reports of anyone EVER getting sick from a contaminated mushroom substrate.
It would be just like forgetting to check your bread and accidentally eating a spot of mold. Sure it's not the best thing in the world, but the chances of it making you sick are very slim.
Did you examine the spots when you cased it? Be sure to post, I'm dying to know the results since my opinion seems to be at odds with most of the other posts in this thread.

I was under the impression there cant be one without the other? The so called "piss" is simply a chemical reaction by the mycellium to foriegn bacteria and contams. This "piss" actually kills most bacteria foriegn to mycellium. Or maybe I'm simply RETARDED lol.

No, it's not specifically a bacterial response. Myc produces excess "piss" in response to metabolic stress IMO. Mainly heat, CO2, and overly long incubation.
RR says it also happens in response to bacterial contams, so I'm sure this is true, but it's not the main cause of myc piss.
> This "piss" actually kills most bacteria foriegn to mycellium.
RR claims this, I don't really find it surprising though. Most organism's metabolic wasteproducts (aka "piss") are toxic to most forms of life. They're wasteproducts because they have to be excreted so that they don't build up to toxic levels and kill the organism itself. Every organism that respires produces wasteproducts, myc is no different.
