It sounds like making marijuana/CBD oil. You have to keep the temps below 200 for hours. It’s like an all day thing.
I have some dried shitake mushrooms that we got out of Greensboro NC. I checked and our local grower does have Lions Mane. I don’t know why they sell Turkey Tail. It is everywhere around here
Could be related to that whole "killed by eating a poisonous mushroom" thing.
We cultivate turkey tail, (Trametes versicolor) but they’re small and it takes a pile of them to make an ounce of powder. I have a new strain of T. versicolor I’m working with now that makes taco shell sized fruit bodies instead of half dollar sized. Hopefully, that will help.
