If you're sitting on your porch having a refreshment and you look across your lawn, you won't see this mushroom. You won't be missing much, but don't let that stop you from looking for it. It's the "pursuit of happiness," not the attainment of it, that motivates us, right? So get up, and walk into your lawn. Unlike some city mushrooms like Panaeolus foenisecii, you won't have to get down on your hands and knees to find A. praecox. Just walk around and look down. Once you find and identify it, you can throw it in the compost heap and return to the porch—and take another sip or two of your refreshment.
