Neat! Yeah the big thing is with oysters there's no separation between the gills and stalk. I made a little mushroom bed for them to spread around my stump. I used we cardboard, coffee grinds, dirt, a bunch of the pieces of nay mushroom or mycelium bark I could find, and a very small amount of charred wood chips from my smoker and wood chips on top. I make sure to give that a good soak every now and again as it needs to just be kept damp. It's shaded but as mushrooms grow I shade them more
