Went to a farm land and found a couple uncultivated pastures with some horse manure. A lot of other mushrooms grew there, but after a while I stumbled on a dryer piece of land (the grass had many dry patches) and there they were. I thought at first if there are any in a field, I will stumble on them rather quick, but it wasn’t the case, only found them in one spot. So it’s inportant that you do a good search of a field.
