Hey guys I would absolutely love to have your input on what sort of species of mushroom this is.

Habitat: Trimmed grass in a park gills: gray stem: grayish white cap: whitish gray to grayish brown bruising: not color change observed really possibly a tinge of brown but mostly nothing location: ontario spore print: currently in the making
found them in the growing in bunches of 2-4 snuggled together sometimes singular but usually at least another within a foot distance
thank you very much for reading and for any input

Looks like some very happy Panaeolus foenisecii.
Watch out for the active lookalike Panaeolus cinctulus with jet black prints.

I'm gonna say Panaeolus Retirugis on most. I have found many upon many Panaeolina Foenisecii and none of the specimens I found showed the same kind of cracking on the cap that can be seen here. I'm not positive, but I think most are Panaeolus Retirugis with one or two being a possible Panaeolina Foenisecii (hard to tell on those though).
I think Panaeolina Foenisecii will show more of a band on the margin too.

I have found Panaeolina foenisecii doing this, and I must say these look much more like them than Panaeolus papilionaceus (P.retirugis).

Panaeolus retirugus is an outdated synonum of Panaeolus papilionaceus.
Panaeolus foenisecii has a cap that cracks in dry weather due to the cellular pileipellis.
The band on the margin goes away when the mushroom cap dries out a bit.
The brown gill color strongly points in the direction of foenisecii.

Like I said, I'm not positive and I don't have any pics of my own, but here are some links of the visual differences from Roger's mushrooms:
Panaeolina foenisecii http://www.rogersmushrooms.com/gallery/DisplayBlock~bid~6558.asp
Panaeolus retirugis http://www.rogersmushrooms.com/gallery/DisplayBlock~bid~6560.asp
Just some observations of mine. I'm sure you guys are right, but just thought I would throw the possibility out there.
BTW, I have never found retirugis (papilionaceus) so this is based off of pictures from presumably outdated books. Also just googled papilionaceus and had no idea all those species were one mushroom. The mushroom world never stops changing!

Rogers Panaeolus retirugis looks like Panaeolus papilionaceus to me. The two species were synonymized by Gerhardt 1996. Perhaps Roger is not aware of it, or maybe he does not agree with the synonymy.
I don't always agree with everything on the rogersmushrooms site. It has more errors than most mushroom websites, for example it says that Gymnopilus can be deadly. When I emailed him to let him know that there are no toxic Gymnopilus species, he asked for proof. I pointed him to the 30 year NAMA case history of mushroom poisoning and he said that was not proof. I was like....I give up, I can not prove a negative.
Panaeolus retirugis grows from dung, and OP's mushroom grows from grass however.

Yeah, I try to use a lot of different sources and honestly his pics were just the best I could find to show the differences I was seeing. Also, it could have been heavily manured grass, I have seen cubensis growing in someone's front yard when I lived in Texas. I promptly stopped the car and picked that bitch! lol.
