This is Coprinopsis acuminata, acute-acuminate pileus is characteristic of this species.

I couldn’t see your images outside of the thumbnails before, now that I can open them I think the apical papilla and veil at the cap margin is kind of interesting. C. acuminata pics I am finding seem to have these features, but the size does seem to point towards C. atramentaria. I don’t recall ever seeing it on the material here, I would show you an obs to show what you what I mean, but large number of my pics don’t seem to work now… Do you have a better image of the stem?

Maybe you could consider C. acuminata too? http://www.grzyby.pl/...

Spore size should distinguish them.
