I’ve gotten into growing mushrooms - I first ordered some kits from a company called North Spore. Here is what I have right now, though the lion’s mane in the upper left will have to go, at least the yellowing part of it.
I also have enoki and maitake mycelium colonizing rye berries in my office closet.
I started doing this because the lion’s mane kit was $28, you get 2-3 harvests. Meanwhile my local fancy store charges $50/lb for them.
