mycelium growing out very transparent

I have some jedi mind fuck plates. 1 plate is 1 transfer from MS and the other is a ms inoculated plate. You can see black on the spore inoculate plate, this is just a tiny bit of the swab I cut off and placed in the plate.
I've never seen a plate grow out and be so transparent. All my other varieties have a clear leading edge while growing but nothing like this. Could it just be due the variety?

What species are they? If there is any mycelium, the Mold has taken over

Cubes.
Really? I dont see any mold on them just mycelium unless my eyes arent trained enough..

I've had this happen before and for me it turned out being too much nutrients in the agar batch.I dialed back the malt in the next batch by 5g and everything went back to normal, but every single plate in that batch caused transparent mycelium.
It was just a simple brain fart that caused me to put in too much on that batch.

I have other plates going that are normal growth. That's a good point though, this batch is 8 grams lme and 10 grams agar

It could be a couple different things. Could have a contam riding along, could be the nutes, could be that some extra dimensional beings sought refuge in the agar.....
They don't look good though. All one can do is take i nice small transfer to a new plate and see what happens. I certainly would NOT advise putting those to grain though.

Thanks for your input. It's very weird as I've never had plates do this and I have other varieties on the fame batch of agar.
I'm gonna throw them and start new plates with the swabs.

I'm seeing something similar (except potentially even less promising) in my MSS-to-agar plates. Pretty much every plate looks like this - is this early mycelium, straight contam, or some combination of the two?

Apologies for the poor pics, they're no-pours and the condensation makes visibility tough..
I'm mainly wondering what I should change for my next batch. I'm also stuck with MSS to agar until I get some jars growing out.

Shoot, I thought so. It's pretty much on every plate, across multiple spore syringes. What is the most likely cause in your opinion? Is it the agar recipe, or the syringes themselves?

It's the syringes. They are by nature host to contaminants and specifically bacteria. As soon as the solution hits agar that bacteria finds food and goes ham. That's why it's uber important to use the tiniest drop of spore solution going to agar from syringes. Even going so far as to moisten a swab to apply. Sometimes that's even futile unfortunately. You can use brf paste (Josex has a great tek for this because he's just a cool guy like that) to get clean myc or run some brf cakes then make prints. The brf paste/pucks are stupid simple to make (just like prepours) and will get you squared away quickly.

Thanks so much, that info is all super helpful. I'm not surprised it's the syringe, I'm getting some serious contam in my grain jars that I'm knocking up alongside my agar plates and the contam always seems to be directly where I squirted the spore solution.
With my most recent batch of agar plates, I did individually sterilize q tips and tried to do 3-4 drops of MSS on the qtip itself then rubbed the agar. Hopefully that will help.
I used Josex' no pour agar tek and loved everything about it so I'll definitely check out his BRF paste tek (which I hadn't heard of). Appreciate you sharing your knowledge.

And I don't remember if his tek specifies, but don't sweat the amount of brf in the pucks. You're just heating up brf and water until it barely is pourable, pouring it quickly, and tapping it gently to level off. As long as it's thick enough to set up pretty firm and thin enough to poooouuuur, you're gold, my friend.

I'm using 8 grams LME and I have other cultures growing out fine. Would you say 8 grams lme is too much ? I'm sure I've seen you reccomend that a few times.

8 grams to what volume of media? Percent is the needed info. 2% nutes is pretty standard.

Hmmm. That’s 1.6% so may not be the issue. Super hard media could also be at play. I know some brands such as telephone are like glass at 2%.

Lab grade agar has a higher gel strength than telephone. Telephone is under 500g/cm but most lab grade is over 1000g/cm some are like 1600g/cm
Lab grade media is usually used at more like 15% but most of us using food grade stuff go with 20%.
But agar thats hardly solid and agar that's hard as a rock all work well. Bacteriological agar comes out extremely stiff mostly to keep colonies nice and pinpoint.

I run 3-4% nutes and see this type of growth sometimes. I run heavy on the nutes and the plates seem to last a lot longer on the shelf and pin more frequently but there is definitely some weird growth patterns with higher carbo content. That's all well and good for me but weird growth to the untrained eye is often precursor for alarm so as mentioned above keeping it around 2% is ideal for "standard" Rhizo/tom cube growth.
Personally I like to hunt mutant phenos.
I have also seen more growth like this when the sugars used are more caramelized, but that's just ME and I traded mycology as a "science" for mycology as an "artform" many years ago and haven't looked back.
Personally I'd transfer some pieces to new plates and see what happens.

If I'm running 500ml 10g agar how many grams of lme would he 2% ?

I think it would be 1g to 99ml would be considered 1% for a final volume of 100ml ([1g=1ml]+99ml=100ml).

Yep. Add dry ingredients and top up to target volume with water. It helps if the vessel you’re pc’ing is graduated..

So would you say to drop my LME to 5g instead of 8g with 10g agar to 500ml water to stop this thin mycelium? I just dont know why I'm getting this all of a sudden when I've always used this recipe on other cube varieties

Were your plates fresh? I suspect older plates may have resulted in similar for me.
I did some transfer of some paneolus cyanescens to a month or maybe 6 week old agar plate that I suspect had dried out a bit. The mycelium seems to stay below the surface of the agar rather riding on top, leading to a transparent sort of look, though it definitely leeched out the dye i used.
My assumption was that the surface was dry and not hospitable but the agar lower down still had enough moisture to be colonized. I'm paused for awhile so haven't tried making some fresh plates to transfer to.

Naa these are fresh plates and have moisture on them man. I looked at a plate I transferred from and it was like a floppy like jelly and it was hydrated if you know what I mean.

I tried 8g agar, 6g LME, 5g activated carbon & 500ml water for this most recent batch of agar. Will report back on difference vs. the standard 10/10/0/500 I was trying earlier without much success.
