[TheUWfarm] Mushrooms and mushroom accessories

Hey everybody-
The Fungi on the Farm committee is looking to get started growing some tasty mushrooms on the farm, but before we go ahead and order inoculants from a catalog, we thought we'd ask around and see if any of you on the listserve have any edible mushroom-growing supplies that you aren't using, or if you know anyone who might, or if you have general ideas or pointers for us. We'd love to do this with as low a start-up cost as possible. Things we are looking for include:
-Edible mushroom cultures or spores. Our plan is to begin by growing oyster mushrooms (Pleurotus) because they are good and easy to grow. BUT, we're not picky. We're on the lookout for any kind of edible mushroom we could feasibly grow on the farm.
-Sawdust.
-Logs. A mushroom-growing log should be at least 4 in. in diameter, freshly cut, and hardwood. Who knows, maybe you have a whole stack of these in your garage.
Any supplies or ideas you'd be willing to pass our way would be greatly appreciated. Thanks!!
Happy farming,
Dan
