I don't know exactly but look at this post
CdC accidentally froze Pholiota nameko mycellium and it survived.

If it was partially dehydrated first, possibly, but water tends to form sharp crystals which, when frozen, lyses cells and destroys everything. But there are certain sugars that can keep water from making these sharp crystals, same way frogs can survive deep freezes. I have no idea what's in the water of mycelium. The middle may have not frozen all the way, give it a try. If the middle could survive your best bet IMO would be casing or mix it with another jar and do bulk. Good Luck

yup, those crystal formations are what's worrying me. i am now doing a slow defrezing, by moving the jar from freezer to fridge, perhaps if the process is slowed down i may be able to save more of it. thanks for the imkput, i'll let you know

Yah, the only reason I mentioned that whole frog thing was that there must be some kinds of mycelium that survive deep freezes. There are plenty of mushrooms that grow in Alaska and Canada and I doubt if they all start from scratch, I mean spores having to recolonize every year. There must be some that are like perrenials - for lack of a better word. Just not sure if cubies would have ever needed this characteristic and more than likely not since they do start from spores almost every time, jumping from one shit to the next. But it will be interesting to see. Good Luck.

I've frozen azure mycelium for a similar length of time in an attempt to kill a bug infestation, it didn't work, but they still fruited eventually.

you mean the freezing didn't work as a pesticide but the myc survived anyway? both the freezing and the bugs and it fruited? congrats

I just got here but why are you freezing things. Is it some super duper cold shocking tek that has been recently discovered.

Comario: Yes, it fruited, albeit a weak fruiting. But I credit that more to the shitty conditions for azure cultivation in eastern washington (cold temps and extremely dry/low humidity) than freezing it or the bug troubles early on. After being put outside, the fungus gnats seemed to leave it and it grew fine vegetatively. Pics of one of the tiny fruits I got are on Sporeworks' site.

Browho4d: If you'd read my post above you would see I froze it in an attempt to kill fungus gnats that invaded the spawn I used.

hey dethhed, good to know, i have my hopes up again btw, i am very familiar with your '99 experiment, you have been one of my guides in my (yet unsuccesful ) quest for growing azures

Are there any tricks to reviving dried and freezer stored agar mycelium? I made some new agar dishes and scratched some pieces of mycelium into the new dishes, but none of the new dishes show any life.
I kind of assumed that freezing would not hurt dried mycelium...

It depends on species. Oyster, P cyanescens, and shiitake can all be frozen and recover. I'm sure there's others as well, but those can for sure, as can reishi and most polypores. RR

I had a Reishi culture shipped to me about a month ago that arrived frozen solid. I thawed it out in the fridge and plated it the next day. It took a little while longer to kick off but is robust as hell now.

Reishi can definitely freeze. Since the OP edited, I see he's talking about P cyanescens, a species which can survive freezing. RR

I tryed to start a DEX-LC from some P.mexicana sclerotia, that were frozen. And one of the two glasses shows growth of mycelium out of the little sclerotiapieces.

I've had Oysters recover just fine from freezing, as stated. My cubes did not recover, however. As stated, it's definitely species-dependent.
