    Howdy Folks!

    I have been trying my luck with hypsizigus tessellatus and ulmarius and on grain the myc seems nice and vigorous. When I transfer it to beech HWFP supplemented with 10% wheat bran and chalk it grows very thin and sickly and never really seems to colonise the bag.

    Are there any perks this mushroom has, maybe a particular PH or a particular supplement I should be using please?

    Sounds like it should be the perfect substrate.

    When you say chalk, what is that exactly?

    Are the bags sterilized or pasteurized?

    chalk is just calcium carbonate.

    i got the tessellatus to colonize hwfp but i could never get it to fruit and gave up on it.

    Yes chalk is calcium carbonate. The bags are pasteurized as I do not have the means to do any better. Anyway, my method works very well with most other gourmet species so I do not see why it shouldn't work well with hypsizigus.

    These are a couple of pictures of my blocks.

    Right on. Calcium sulfate is also called chalk and is in fact, what blackboard chalk is.

    How long has it been since the bags were inoculated?

    I can't speak to ulmarius but tessellatus takes about 8 weeks before it starts to pin in vitro and you can expose the primordia.

    It might just be the angle but it also looks like there is some green in there.

    inoculated on the 9/11/16.

    No there is no green in the bag, I would have noticed it.

    If there's no contamination and all of your other parameters are fine (FAE and Temperature would be the two crucial ones), then you've got me stumped.

    I can't tell how your bag works as far as FAE goes but high co2 could slow them down also.

    Sorry to hear of your troubles

    I havent been able to get my ulmarius to fruit yet either, despite various stress methods I have thrown at them

    The mycelium has been growing nicely, but no cigar beyond that point. I am chopping up current the blocks now for mixing in to outdoor areas, and making dowels for log inoculation. Then I will start fresh from agar, and try again

    I am mostly blaming heat and dry air

    Sorry I am rereading the thread and I can see I have not been specific enough.

    The picture is of an HT bag. With HT, the growth on grain is fast and strong and the myc is very fluffy and soft looking. Once I transfer to HWFP, growth slows down and colonisation is extremely poor.

    With HU, the story is a bit different. Growth on grain is still very vigorous and strong. Once transferred to HWFP, the growth remains very strong (similar to PP but I would dare say stronger and faster!!!) and soon I will be able to tell if I will manage to fruit this one or not.

    Heres some i did a couple years ago. I don't remember doing anything special. Maybie they took a while to fruit. I dont remember.

    That looks like the infamous "psuedo-ulmarius" - it's really a Pleurotus spp.

    I think he's talking about the true Hypsizygus ulmarius, which I've read is harder to fruit.

    That makes allot of sense. Something didn't seem right. It was labeled "elm Oyster".

    Yeah. Somehow, it has been distributed under that name by even the big names in spawn production.

    I've never grown it but I know it's a great producer and a lot of folks really like it.

    Yes I am talking about the real hypsizigus. Here I am posting two pictures of two bags, the one on top with the cottony growth is the HT whereas the one on the bottom with the very strong colonisation is the HU. Fingers crossed!!!

    So one is the HT amd the other one is the _other_ HT?
    :pipe:

    My guess is that the issue with the slow grower is that it doesnt like the nutrients in the bag
    When i started growing pulmonarius and Ulmarius I had some anemic looking substrate jars before i supplemented the mixes. So try and experiment with some different things in the substrate, like shredded pepper or other types of wood

    Yes yes, it is HT and HT, can't you see the difference :)

    Sorry for that, I corrected the post!

    Living on a semi desert island does not give you much space to experiment unfortunately as wood is rare and dear! I will try adding ash, paper and fir to the mix and see how it reacts to every individual sub.

    Paper made the difference for me

    Pine saw dust was a deterrent for some of my spawn runs, but Ulmarius wasnt one of the,

    Best of luck! And please keep us posted, as I am very curious about how it goes :)

    @Nichrome Since you have actually fruited Ulmarius before, can you tell me if they look anything like this when pinning? I can't find any photos of them at that stage anywhere.

    This photo is from one of my Ulmarius blocks abandoned outside in a planter. Haven given up on them, I have stressed them so much over the past month, that it could be anything growing out of it now (I have seen straw mushrooms already)
    This particular block fell and partially broke about a week ago, and I now got these pins in it. They have been growing slowly for about 3 days now. I'd have guessed them to be this local straw mushroom, but they grow and die within a day.

    Hey @muskie, I am still trying; I have not fruited it yet. However, those pins look like coprinus comatus to me.

    Thank you

    Since last night they popped. About 10 centimenters in ~8 hours. They are very similar to coprinus comatus, and the cap vanishes in no time, but they don't look like what I am used to seeing in Europe, so no sampling for me.

    They are called straw mushroom around here because they pop out of seemingly nowhere on grass / straw cuttings

    This yellow concoction flowered in about the same 24 hour span as the mushrooms above. It's already started wilting

    This is from last night, before it wilted
