If i plant a magic mushroom in the ground will it grow more

someone asked me..

It's not impossible, but it's highly improbable. It would have to be young enough, intact enough, and robust enough to produce viable spores, which would only produce more if very exacting conditions (temperature, growing medium, moisture) were met. It's unlikely you'd find one that met those conditions, and be able to provide what it required.
