Mica caps are a type of inky cap, Coprinellus and Coprinopsis are close relatives and both can turn to ink. They only have the sparkly particles when they’re fresh, these are starting to turn to ink so it’s not surprising they don’t have it. Coprinopsis atramenteria is usually larger and duller-colored.
I think they may be inky cap https://en.wikipedia.org/wiki/Coprinopsis_atramentaria
I’ve seen these all over Chicago, usually growing near the roots of a dead tree. I’ve been told in the past they were ink caps of some sort.
