Am I able to grow button mushrooms in my garden?

Hello I am very new to gardening, I am going to start my garden in a week or so in my backyard. I heard that you can grow white button mushrooms in just soil

So my question is, if I just take a spore print from white button mushrooms and put them in the soil, will the mushrooms just grow? Do they need something else? Also will the mycelium just take over the entire garden?

Thank you for any advice.  

I fail at mushrooms, but my understanding is they would grow on the mulch, not the soil. Please correct me if i am .wrong

Morels grow in the soil . Spawn mixes into soil, then bury kitchen scraps to feed it.

If I remember correctly button mushrooms are secondary composers.
So they would grow on your finished compost and or aged animal manure.

Right now I have started a button mushroom kit that looks like gray cobwebs on straw and black compost that needs some added water and gets put on top.
The mycelium has grown through the compost and looks white against the black. I expect pins in about a week.

When the kit is finished I will mix it with finished compost in the garden.

A friends dad got a permanent button mushroom colony established near his compost heap in this way.

No, it will not take over the whole garden as there are other interested parties that will make sure it will stay in it's ideal niche if at all - there is constant war going on out there and your role is to play faith for trillions of organisms.

I've just had 5 flushes of field mushrooms (Agaricus campestris) come up from the bottom of my compost bin after spreading some mycelium slurries around.
Field mushrooms are the same genus and almost identical to button mushrooms (Agaricus bisporus).

Commercial button mushrooms have probably been bred for various properties, including hardiness.
I have heard of individuals growing them in railway tunnels and in boxes of compost either under dirt or a lean-to.

You can do it. But it’s very complicated. Why not buy a mushroomkit to start and learn? What else do you want to grow in your garden?
I dump button mushroom spores every year in my garden. A few popped up. Mushroom spores are everywhere. Every breath you take you breath in millions. The wild species are much better adapted to overtake a substrate than the ones adapted to suit our taste buds. It’s hard to make the ones win we want to see.
I’ve cut a log in the forest that had loads of oyster mushrooms on them and transplanted it dug it in so it kept moist. It flushed when i was on holiday.

I am new to growing mushrooms at home and indoors, I am trying my hand at White Button mushrooms and have read a lot of different How To Instructions but I was wondering if anybody knows Why my mycellium is grown downwards in substrate and not upwards to the top? Is this a normal process and i just need to be more patient?  Any help would be greatly appreciated.
