Why have i got wild mushrooms growing in my garden?

Answer 1

Are they wild mushrooms ? in any case don't eat them.

or knock them around it will make the spores scatter causing more of the same.  They will eventually die off and actually enrich your soil.

Most fungi in lawns are beneficial because they decompose organic matter, thereby releasing nutrients that are then available for plant growth

This is how they get into your yard

LIFE CYCLE OF A FUNGUS

Fungal fruiting structures release tiny spores that are easily carried on air currents to new sites. When spores reach a favorable place to grow, they germinate.

Answer 2

Mushrooms are the fruiting body of a fungus growing underground.  The fungus is consuming a good hunk of organic material.  It could be dead underground roots from a nearby tree, large chunks of manure you plowed into your garden, who knows.  I doubt the fungus is attacking your garden plants unless they are dead.  Think of mushrooms and the parent fungus as Nature's recycle center, recycling dead or dying organic materials.  

Answer 3

if you didn't spread the spores then yes.
