Common Nature

_{I just think mushrooms are neat and have others I've found recently that I will eventually share.}

Recently, I discovered what I believe are puffballs in my front yard! I've never seen any alive before, so I'm relying on Google. The mystery comes from the brown one. (It is the same mushroom as the first photo, where it is obviously paler.) It didn't used to be brown, but there is a brown umber puffball.




One of the white ones is still white, so it could be a common puffball or a peeling one. Peeling would make sense, if that little bit in my hand (the only bit I found) is from the mushroom and not its own decaying corpse. The bit was near the now-brown puffball, though.

I'm really not sure, though. ¯⁠\⁠_⁠༼⁠ ⁠•́⁠ ͜⁠ʖ⁠ ⁠•̀⁠ ⁠༽⁠_⁠/⁠¯ Any aspiring mycologists have like a list of criteria to determine a species?
