Yellow knots - ‘dry bubble’ / Lecanicillium fungicola /vert ?

Hi guys,
I posted this picture also in another thread, but I think this somehow got lost as I did not receive answers. Thus, sorry about the double post.
I spawned this shoebox 11 days ago and since 2 days I get those yellow knots forming. Is this something to worry /do about? Or should I just relax and wait?

Edit: some commenters remarked that it may be Lecanicillium fungicola or otherwise known as ‘dry bubble disease’.
Here are two updated pictures:

Seen similar growths in my buddy's stalled out tub. Not too sure if it's bacteria in the myc, or a seperate contam entirely like a fungus. My guess is the latter, unfortumately.

Oh that’s really bad. Should I toss it directly?

If you have other grows I would seperate it from those just to be safe. I could be completely wrong it might just be a variety of mushroom I'm unfamiliar with etc..
Regardless, your surface conditions look pretty damn good, I'd keep experimenting with it. IF it is a contam it likely started very early with your spawn.

Thanks for your reply.
I am pretty new to this and it was a GT MSS. No agar, so it is pretty likely that it was contaminated from the start. I will wait a little with this tub before throwing it out.

ahh id keep them going man, looks just like primordia may of got a little dry. yellowing oranging is usually just myco pee. i suspect keep up FAE and moisture levels may need to lower temps if is a bit hot?? you will get fruits i promise when myc dies and strange colors or smells seem to overtake the myc then u need to start worrying.
myco pee will often form little bubbles that seem to float on myc kinda what it looks like on some parts in your pic.
remember to take advice from non trusted cultivators with a grain of salt. lots of bad advice, not saying buddies wrong but just a general rule.
cheers

You’re ‘the man’.
Got some pins today. :-) seems like the yellowing is not getting worse. I think it might have been stressed because it was a bit on the dry side in the beginning and then I might have shocked it with too much misting at once.
Anyway, now that fruits are appearing I can crank up the FAE a bit more, right?
Thanks again for your replies guys!

It LOOKS like Dry Bubble Disease, used to be called verticillium fungicola now called Lecanicillium fungicola.
It is a myco-parasite and can infect all of your prints and pull your pants down and spank your bare ass for months and months and months.
Could also be wet bubble disease aka mycogone. If there is an extensive amount of brown/amber micro-droplets on the blobs it's likely mycogone.

I had the same thing I believe in a tub a few weeks ago. It left the first flush stunted and funny looking and I kept the tub off by itself and didn’t mist it. The second flush came in looking normal and then I think I tossed it.

2nd flush. And I remember now that trich had taken hold in a few places during the 2nd.

Oh no. That doesn’t sound so good. I guess it is best to separate this tub / put it outside. Anything else I can do?
Unfortunately, I already listed the tub and got a few more tubs really close by. Roomy mistake i guess, it is my first grow.
Maybe some more people can chime in on that. I could not find all too many pictures of mycelium infected by Lecanicillium fungicola. Here is an updated on how the tub looks right now.

That indeed pretty much looks the same. I also got these very tiny brown spots on the yellow knots. (I uploaded some updated pictures in my previous post) But at least the fruits seem to look okay. Unfortunately, I left it really close to my other tubs and also misted I think.
How did it go for you? Did it infect any other tubs/future grows?

No I haven’t seen it again since then, though it’s only been a month or two. I don’t know much about the stuff but I’m going to read about it because I’ve heard the names mentioned here often enough.

That gives me hope. I put the tub in question on the balcony. Pretty quickly drying out there but I figure it is better to separate this.
I also recognized some free in/blueing in the tub. Is this just the mycelium bruising from stress or some mold? Here is a picture:

These contaminations can lead to mold, particularly if it is wet bubble. It just overall weakens it. Bad weight, slow colonization, everything is made worse.
Looks like maybe blueing but if you look really close in the center area there may be some blue/green mold showing. Better closer shot of center?

This is the closest I can get a shot. My guess is bruising, but would be great if anybody more experienced could chime in. Also, would you guys eat those fruits with all that stuff going on in that tub?

I consigned all the fruits from that tub of mine to the chaff pile for tea or extract. Idk if there’s any possible dangers at all (I really doubt it as long as they’re dried) but I have a ton of clean cubes and I didn’t wanna be thinking about that weird tub while tripping lol.
