Lambo, welcome to Permies!
I hate to be the bearer of bad news, but I don’t have much confidence this is going to be productive in the way you want it to be. That being said I would go ahead and try to inoculate some media with it.
Going forward I would order again from a reputable supplier. Adding in fungi can do wonders for your garden.
Btw, what fungi were you trying to grow? Are you trying to grow this for mushrooms or were you hoping for
compost or other microbial interactions? The more information you can give the better information we can offer.
Sorry about your apparent rip-off,
Eric
