What media do you grow your Oyster mushrooms in?
Has any one grown edible mushrooms on Horse manure and straw?
My Brother has a horse barn and lots of mixed pooh. 12 Ft high last time i was there..
Still looking for info re: can one eat mushrooms from Lagoons.
I like the fact that they can clean the water .. it would be nice to get a crop from it if it was safe to consume.
Oyster mushrooms are great generalists, and will grow in most dead woody tissues, from logs to toilet rolls to coffee grounds (although they don't like conifers: those have to be preprocessed).
Horse manure will support a different class of "secondary decomposers" (oyster mushrooms are primary decomposers). Traditionally, that's what conventional white mushrooms were grown in, but you really need to pasteurise it first. In practical terms, this means composting the pile. You can find instructions online, but I've never had access to enough horse manure to try it.
Lagoons are a complicated one. You can use fungi to clean runoff (Paul Stamets' books contain instructions and I expect Peter McCoy's does as well), and in theory you could eat the mushrooms, but they may bioaccumulate mineral toxins, so I'd think twice about it if you aren't sure about what went into the animals that created the manure.
