That species doesn’t have a veil nor an appendiculate cap margin from a veil and is usually whiter. Non-hygrophanous, with an appendiculate cap margin, reddish stem, and on dung strongly suggests P. papilionaceus. Microscopy would be cool though.

Panaeolus sp.

I will see if I can get some more of these mushrooms this spring for micro. However I think you might be right Blood W.

the stipe is way off.
it is too thick and far too brown-ish.
Panaeolus papilionaceus has a thinner/red stipe.
these deserve micro.
