Can you grow/inoculate any species of mushroom using vegetable-tanned leather as the bulk substrate?

    Hi,
    I'm Dali, and I'm new here.

    I'm looking for a way to recycle or degrade veg-tanned leather (cured animal skins treated with plant tannins- Tannic acid, Gallic acid) and was wondering if theoretically it could be used or converted into something used as a substrate.
    The thinking was that it must not be that different from an animal decomposing in a tannin-rich forest floor and so there must be some sort of fungus that has filled this niche in the natural world.


    <as a disclaimer I do not know too much of mycology and cultivation but I figured it'd be an interesting discussion nonetheless>

    I'm not sure on its use as a fungi substrate but they are organic decomposes and it is definitely organic.

    In my bushcraft and woodcraft hobbies I've done a bit of leatherwork using veg tan, so my thoughts on it being used safely as an organic contribution to some sort of substrate mix is to what method was used to veg tan it.

    in the olden days vegetable tannings was the name of an actual process but is now the common name for the end product regardless of tanning method, so if it has been naturally tanned with all natural non toxic tannings {many natural tanning sources used for strong colour are highly toxic if consumed} for the colour then I'd be game to feel safe having a go at using some in a substrate and telling us all about it, good or bad.

    If it was tanned using modern chemicals I'd give it a go if I had nothing else to use but I'd not eat the fungi if it worked, if it was just a matter of returning the skins to nature via fungi with no care for eating the fruits then again I'd give it a go, I remember reading about Stamets using Oyster fungi to clean up oil spills and the mycelium ate the oil and made non toxic fruits

    Yeah definitely wouldn't want to eat the fungi after, purely for recycling purposes.
    Are you saying you'd be interested in trying it out? Id actually be open to compensation for materials if you shared the outcome afterwards!
    The stuff I have comes from mexico and I have no way of knowing exactly what is in the leather due to tanning recipes being so protected, but its safe to say that it has primarily been treated with tannins.
    I'm going to work on this during spring, but being new to the subject I don't think Ill make much progress til summer ahah.

    Thanks for the response, though! :)

    No mate I currently don't have space to grow, I was speaking in the third person as if I was in your position with an excess of veg tan to recycle, I'd probably make knife sheaths out of it all if it was in big enough sheets and strips

    Id give it a try with oysters. You wanna mail me some skin ? I dont need any compensation and will do it for free.
