Psilocybin mushrooms?

I am "not" a amateur grower. And "wasn't" wondering how to get started. so I was wondering, There is this hollow stump I "didn't" fill with dead tree chips, manure, and horse dung,you need anything (ex. Seed/spores) , or is it a waiting game? It is spring, so it rains periodically, then becomes warm and humid, witch makes perfect conditions. I "do not" have a identification guide, I "havnt" studied growing guides. I just wanted other users input.
