UPDATE - 15 Days after drop to agar:
Have a look at he OP for more details.
11 Samples in total 5 are showing clear growth 2 are showing probable new growth 4 are not showing any clearly identifiable sign of growth yet.
Conclusion so far: this seems to work better than dropping them straight to LC, "PanCam I" showed growth after 10 days in LC broth during the previous test but still doesn't show anything here yet. It would be necessary to drop more than just a couple of kernels onto the plates to get a more average result as some kernels might not be viable or take longer to reactivate.
PanCam "B"
after 5, 9 and 15 days on agar

PanCam "C"
after 5, 9 and 15 days on agar

GymPur
after 5, 9 and 15 days on agar

Papuana
after 15 days on agar

Poplar
bacterial growth showed after 2 days. Mycelium has started to grow as well after 8 days but it's still to thin to get a good shot of it. The visibility of the plates are poor but you can see some of the hyphae relecting light on the second image. Well its bacterial and not too happy.

Updated OP with the following:
Revival Test Part 4
This will be the last test trying to revive dehydrated grain spawn. This time I will try to revive the grain that hasn't shown any grows in the previous two tests. What I'm doing different this time is putting 10+ grains on each dish to get a better chance of having viable kernels on the plates. I still got some more dried cultures that I haven't tested yet but will leave that for sometime later. I might repeat this from scratch and try a more controlled drying method in a chamber with a salt that will buffer the humidity in the chamber to a certain level so all grains will dry under the same conditions....maybe but I am keen on trying some other things as well and there is only so much time so we'll see.
Grains dropped to agar on August 11th:
 *Added a second Sub culture, LME and BRF indicating the LC nutrient use for the culture.
You find the updated table in the first post.

Update Revival Test #4: 18 days after drop to agar
Sub BRF
3 out of ~50 kernels of the Subaeruginosa spawn made with BRF LC are showing new growth after 7 days on agar. Second image of fully colonized plate after 18 days.

Same, cool stuff.
I take long breaks from the hobby, and I'm interested better storage. I recently attempted to start back up and realized the culture slants long forgotten in the back of my cabinet were dried up. I had no luck reviving.

Last up date:
The cube spawn that was in dry storage for 1 year 7 month pinned.
I'm very glad this clone came back to life as I lost my other cultures of it.

For final conclusion see OP.
TL;DR: wished it worked better but that is probably due to process flaws, a more refined dehydration method of the grain spawn will probably yield better results.
Moving on to other long term storage methods now......when I find the time....

So let me clarify, those are completely dry grains? Or dry to the point of forcing the myc into a hibernation like state? Which seems more likely.

Some of the grains I took out after 2-3 weeks and some I forgot about and left them in there for a couple of month. I actually have no idea how dry the individual batches of grain were that, my fridge can dry small mushrooms fairly quickly to the point where they are cracker dry. So I guess some where totally dry and some might have had still some moisture in them.
If I would do it again I would, as said before, do it in a chamber with controlled humidity at ~10% or even less, but I don't have the time to figure that one out, sounds more like a retirement project 
In theory the mycelium should survive even when completely dried out as some of the papers suggest that I read, its just a matter of doing it the right way. In one article I read that they had the myc grow over sterilized paper tissue that was placed on a petri dish and dried the paper for long term storage, that I might try with a couple of species, already sterilized some paper.

Interesting, this makes me ponder if someone could biopsy Enigma or clones for example. That's dried completely. As this could make it much more convenient to obtain. But The biggest difference is most dehydrators are far beyond 109F. Which is when spores\myc start to die. At least so I've read. You know how that goes on here, with a grain of salt lol. So for said experiment to even be done. Someone with a culture and a means to dehydrate at low temps would be needed. A fridge I suppose. It would be pretty epic if possible. But from what I've seen, people using traditionally dried fruit have issues with contams. It would definitely be a challenge but hey never know might be the next breakthrough right.
Good luck to anyone who attempts this, I'll be crossing my fingers

Yeah the challenge is to dry the samples while keeping them sterile as the mycelium will take a while to come back to life. Freeze drying might be a good way to do if you have such a machine at hand but you still will have to have the samples inside of a filtered container/jar, no idea how well this might work.
Gotta keep it sterile and no heat.....wished I had more time.

Hello baba yaga, is it possible to know the composition of LC please? is it water and honey only? or is there something else? thank you

Light malt extract is all I use for LC, concentration for these tests was 1%.

what do you mean by 1%? 10 g/l malt extract? do you use distilled water or will tap water do? thanks

Yes, I used 10g/l for the tests, TBH after I did these tests I thought that I could have dropped the nutrient concentration down to what I usually use for LC which is 0.1% so 1g/l.
Using distilled or at least bottled water cause it makes a clearer broth than my tap.

Thank you for your answers :le sourire:, one last question :sourire:: does the quality of the mushroom play a role in the culture of the mycelium? make a culture on agar plate or LC with a mushroom resulting from a 1st generation and another of a n generation will have the same result? (growth speed, color...) ?

Sorry, I don't think that I really understand your question? That's probably because I don't know where you are coming from and where you are planning to go with this.
It would help to explain what the bigger picture is, like how are making your cultures and how are you planning to use the dehydrated cultures.
You read that the experiments gave me mixed results and about half the cultures wouldn't come back to life?

I also had trouble reviving things
Was dehydrated tiny (3 x 3mm approx) chips of wood from some woodlover stuff I'm doing
Dehydrated in a filtered little mycobox like what the kits come in, I left it about five months at ambient conditions to dry out and then put to malt yeast agar plates for revival. I poured those a bit hot so there would be some added condensation to wet the chip once it was transferred in
Azure revived but cyan would not, even though you can see mycelial white on the chips, it just won't jump off. Been about six weeks and plates are otherwise spotless. I am keeping them around to see if anything happens but it looks like a fail on revival for me also... Well 50% success rate anyway
I think the method itself has some promise and potential, but there must be a knack to the dehydration that allows revival, something I'm not fully understanding, to make it work right 
I look forward to seeing what you can figure out in the future Baba
