The name of the mushroom species would most certainly be helpful. Otherwise it's a bit like saying 'I tried to keep a vertebrate as a pet one day but it did not go well'...
However, for most commonly grown mushrooms, learn how to make a liquid culture and then over-inoculate with that.
Liquid culture is the missing link between 'esoteric science' and 'anyone can do it' when it comes to mycology.
