I know that mushrooms identification is a difficult process. but I would like to ask for help in the identification of this one.
It growth over the grass in a backyard on Toronto, Canada.

$\begingroup$ If you still have access to the mushrooms, it would be helpful to know the spore color. In case you're unfamiliar with how to find this out, you can take a 'spore print.' Remove the cap from the stem, place it on a piece of paper (or preferably aluminum foil), cover it with an upside-down glass, and wait at least 8 hours. The cap will deposit spores on the paper, and you will be able to see the color. $\endgroup$– EonemaSep 8, 2022 at 3:57

$\begingroup$ Amazing picture, by the way. These are very photogenic. $\endgroup$– EonemaSep 8, 2022 at 4:00

$\begingroup$ Added the spore print. Thank you for the instructions. $\endgroup$– herachoSep 10, 2022 at 21:26

$\begingroup$ Brilliant. I would call that black from the picture, but do you see any tones in it? $\endgroup$– EonemaSep 10, 2022 at 21:46

This is most likely a member of the genus Panaeolus, based on the black spore print (distinguishing from Psilocybe and Conocybe), growth in grass (distinguishing from Psathyrella and Naematoloma), small stature and thin stem, bell-shaped cap, brown cap and gills, and lack of a ring on the stalk (David Arora, Mushrooms Demystified). The gills in the photo appear mottled to me, which is a diagnostic feature.
Unfortunately, species in this genus are especially difficult to identify. Michael Kuo writes on Mushroomexpert.com:
Beyond a few "easy" species, identification in Panaeolus requires microscopic examination, a good interlibrary loan desk, and the ability to read French and German.
Panaeolus foenisecii is a common member of this genus with macroscopic characteristics that match your specimens (see Mushroomexpert.com and MykoWeb for detailed descriptions). The cap in this species changes color when waterlogged, which would be worth noting if you see it again. However, I am unsure of this ID without microscopic observation.
