The genus Coprinus has been largely torn apart in recent years and as such C. plicatilis is now known as Parasola plicatilis since it is not closely related to the type species of Coprinus (C. comatus). Many mushrooms from the old-school Coprinus genus look a lot like this and often get bundled into plicatilis. The reality is that they can be extremely hard to accurately separate without scientific study, especially in areas outside of Europe & North America where the native mycology hasn't been so carefully documented.
But we can tell some things from these photos. Firstly, they appear to be too big for P. plicatilis and all the other Parasola species I know of, but more important is the small scales on the top of the cap. These are remnants from a universal veil which would have covered the mushroom when it was young and are not present in any Parasola species. We can also be confident it is not a true (current) Coprinus species since there are only 4 or 5, all of which are too large so that leaves us with the two other genera split from the old Coprinus genus - Coprinellus or Coprinopsis. Someone more experienced maybe able to tell you which of the two it is, but I am not sure.
