Oysters are about the only native fungus I can easily buy spores for, I'm not sure if the oysters I can buy are the same as the ones that grow around here though. I've got a few native mushrooms on the property only two of which are edible one is not worth eating and the other is restricted to growing only on elder (I have seen it on rowan as well once) Most mushrooms are very picky about where and what they grow on, so the ones you see all the time like winecaps are an exception, they will grow on many different things, are easy to grow and taste ok.
Every time I pick chanterelles I leave all the tops and waste under my big beach tree, it already has two other native mushrooms there that grow with chanterelles so I live in hope. there was a lovely thread here on Parasol mushrooms
Establishing a garden patch of parasol mushrooms and Richards successful attempt to "transplant" them. Now I know where some grow on a roadside verge not very far from me and I have exactly the same conditions here so this year I will try and make a mushroom slurry and introduce them. But of course that means I have to find the mushrooms first it's not as easy as going online and ordering some spawn.
