Haha that picture makes it look terrible but I promise it's quite healthy. We trimmed the bottom so that's why there are dead leaves in the soil. That plant was actually the runt of my 4 plants and ended up being long and stringy as a result. However it actually grew two leads and the second one looks pretty good. Here are some pics of it (kind of hard to take because it's in the back) and the rest:
Some burnt leaves there from when we had to go out of town for a week and they grew a little too high, but other than they are well taken care of and are very healthy.
A mushroom like that is doing absolutely no harm in his garden, it may turn into 30 mushrooms ud have to pull, but thats about the worst. This being said i hope he removed it.
