Comment: This species is very close macroscopically to Panaeolus subbalteatus except it is smaller and does not have verticle grooves runing up and down the stem and it does not stain blue. Also, Panaeolina foenisecii's cap never becomes flat and upturned in age as does Panaeolus subbalteatus. This species is common in lawns and is known throughout the globe as the "Hay Mower's" Mushroom.
