Is there a wrong time or place to use mushrooms?

I'm just starting to learn about mushrooms and all the amazingness that is them.
I want to buy/gather an assortment, blend them all up and spread them around my yard.

If it works, I'll have an assortment of mushrooms growing around my yard in whatever locations they prefer.

Is there any reason this might be a bad idea?

If somebody has bad allergies, that might be a problem.

I would start with mushrooms that are well adapted to your particular climate.

Ditto on the allergies! I made the mistake of going "all in" one year growing oyster mushrooms indoors. I nearly died... no joking. I found out I am allergic to the spores in a confined area. I was really, really sick for several weeks and couldn't put my finger on it. All of my mushroom adventures are outdoors now with a face mask and protective gear. I can eat them but not breath them....
