Found on a slight hill in dirt/grass, where water was dripping down onto the sidewalk near the 2 clusters of unknown fungi. Spore print is black. While they don't deliquesce (maybe the edges a little this morning), I keyed these out to Coprinus micaceus based on the striations on the cap, the fact C. micaceus doesn't always deliquece, and the glistening particles that I see under a lens but MD says the cap would be tawny, whereas mine are green gray. There were several other possibilites I keyed out to, but am unsure.
