So I’ve been growing mycelium on cardboard to prepare it for some sort of happy life in a substrate. It’s just a few sheets of cardboard. I left it too long, alas, and now there are white dots in the cardboard mycelium. Does it mean it’s getting ready to fruit? And what kind of fruit will I get on three small pieces of cardboard? (Presumably not much). Would I get any sort of mushrooms at all?
Mostly, can I still throw it into my bucket of soaked cardboard, coffee grounds, and wheat bran, or would it mess it up?
Those could very well be mycelium deciding to condense and form fruiting bodies. Might have had a moment of perfect conditions to trigger it to try fruiting but the mushroom bodies themselves likely wouldn't develop very far IF they continue at all. Still totally usable for continuing to inoculate more substrate. Do you know what kind of mushroom it is, or are you just cultivating at random for breaking down wood?
