Recognized by sight: Looks like a toss up between Coprinopsis and Coprinellus to me, not really like what I understand C. lagopus to look like, but that is a difficult if not impossible group without microscopy.

At the risk of repeating myself, you’re going to need to take this option in the key for this to be Parasola.

“1. Pileus without veil, smooth or with setulae and/or setae; section Pseudocoprinus”

But since this has a veil and is not Parasola or Coprinellus sect. Setulosi, you’re going to need to take this choice.

“1. Pileus with veil, without setules or setae.”

do not deliquesce as far as I am aware, though the name i have proposed is Psathyrellaceae also includes many of the inky cap genera as Coprinopsis, Coprinellus, and Parasola. Though, there are some blurry lines between Psathyrella and inky caps, see species like Coprinopsis marcescibilis (Formally Psathyrella marcescibilis) or Parasola conopilus (Formally Psathyrella conopilea). I still think this is either Coprinopsis (Maybe something related to your original ID, but I’m not sure the veil is quite right?) or maybe a Coprinellus. Europe-coprinologist might have a better idea if he sees this observation, but there is probably little chance of getting this to a confident specific id unfortunately.

Do Psathyrella turn black and deliquesce?

Look at the gill edges. They are also pure black, not brownish black.
I should have gotten a shot under the cap … Thanks for the chart. I’ve recently read Buller’s Researches on Fungi, and P. plicatilis was closest match to those he discussed (in some detail)

No way

Is this Parasola with that veil, see this chart.

Also see the keys here to better explain my hesitance with naming this. Here is the key which contains Coprinopsis lagopus which still may be relevant to this observation? Also note that these keys while still useful for the states are intended for Europe and I think chances are we have at least a few species here which Europe doesn’t.
