Does anyone recognise this powdery white stuff? Is this contamination?

Does anyone recognise this powdery white stuff? Anyone had that before?

And do you think the tomentose-like stuff is PO (Pleurotus Ostreatus), or contamination?

I inoculated grains (rye) with PO LC, which I cloned from my master LC. These clones have tried to start to pin in the jar already. No idea whether that is relevant, but that is why I state it.

A few days after inoculation the powdery stuff appeared. And a few days later the tomentose (?) growth.

Is the powdery stuff maybe chalk? Mini knots? Or is it a known contamination?

PS: the QC of the LC (on petridish) showed the same tomentose stuff. Not the powdery white stuff.

Powder:




Tomentosious:

Keep an eye on it but that "powdery" growth ime is usually just some bits of dirt or dust that the mycelium condenses around.

Thanks!

I'll give an update in a few weeks whether it gave fruits or fails.

If there is more info available about this 'powder', I'm very interested to know.

What I also remembered, is that on the outside of the jars, there was powdery chalk residu after sterilisation. I'm not sure anymore whether I added some acid in the pressure canner, but I think I didn't.

So far so good. The jars are transferred to straw yesterday. The jars smelled good, looked good and inoculation seems good so far. Or at least I think they smelled good and looked good. And I hope it actually is so. We'll know for sure in a few weeks.

Ive had these powdery stuff once too. It looked similar to your pictures but in my case it was cotamination and turned green after a couple of days

Thanks.

A difference with your photo is that mine had also mycelium (or at least allegedly at that time).

I have a new batch of jars going and also on those again I get some powdery stuff, though only a fraction of what I had before. And only again for the PO variety, the other doesn't have it at all. And it seems to be mostly at the spot where the LC was sprayed and got into contact with the rye and glas. Unfortunately I did not took a photo, elsewise I'd shared it. Anyways, still not sure what causes the powdery stuff. But it did not hinder anything I think. I just finished flush 1.

Maybe ist really just only dust or something and yours was eaten by your mushroom and mine by the contamination

Yeah, maybe. Dunno.

I did made a picture yesterday, but it doesn't really show the powder very good, but a bit.
