Description: Original observation #568775 (iNaturalist)
Occurrence Remarks: Around 3:00 pm i saw a huge white thing that i had mistaken as a ball. However when i got closer i realized it is what appears to be a mushroom. This mushroom is about 15 cm in height and about 20 cm in width. The smaller mushroom next to it is around 5 cm in height and 7 cm in width. The weather was fairly nice, 24 degrees celsius. I noticed that similar mushrooms that are much smaller are also in this neighbor's lawn.
