Fruiting triggers for Buna shimeji / Hypsizygus tessellatus ?

Hi! I'm trying to grow some buna shimeji from an asian supermarket clone. I started cloning 5 months ago and got a clean culture on agar. The agar plate has pinned and is extremely slowly growing some thin, weird pins? Is this really what the pins should look like or have I accidentally cloned something different? I made several plates and all have the same weird pins, so they most likely are all shimeji, but I would like to hear if you know what they should look like.
 
Anyway, I put agar to oat grain and then mixed 50/50 with coir. The sub started pinning over 1 month ago. There are still more pins coming everyday.
  However I want to start fruiting soon. Does anyone know what triggers fruiting for Buna shimeji?

I wish I could offer more help, I did it a few times but was never quite able to pin down what exactly they wanted once they got to those little skinny pins...
I can tell you that they will abort very easily when they are at that stage. The best block I got was when I went on vacation and left it in our screen porch with the bag just loosely folded over the pins, no fruiting chamber or anything. It was pretty cold outside, and not very humid. When I got back I saw there were some fairly good mushrooms going, so I then threw it in the fruiting chamber, and they grew fine.

But if you try to baby those little pins and give them all sorts of moisture you'll find they abort easily. So maybe less moisture? And cold seems to be a factor. I have wondered if a casing layer might help as well, but never got to trying it... Also thinking supplementation would help as the yields were pretty crappy, but I don't know how well the blocks would resist contamination as they are extremely slow growing.
Hope this helps. Please post your continued results so I can finally be able to give people a definitive answer on this one! It comes up every now and then. Good luck!

Do you remember how cold it was? I have generally kept my substrate a bit cold. Around 10 to 15 C. Maybe I should just put it into my fridge and see if it helps. Fridge is cold and dry, so similar to the conditions you described.

my (brown) hypsizygus tesselatus are also growing right now. 10-15 C should be perfect. Very high humidity is desirable. look here https://www.shroomery.org/9402/Hypsizygus-tessulatus I still have bags where the primordia are really small. Will take a picture tomorrow.

Are you sure that's not P. eryngii in the pic?

I'm sure. buna shimeji.
The stems won't get as long as I want them to be. My co2 in the growth room is currently very low because I also have P. ostreatus and Shiitake in the same room at the same time. Not a good schedule from me. In addition, I cut the first sack too far down.

Cool! Well in that case I'll take the substrate out of the fridge again and just see where it goes :P
