Pezizales, at least haha Ascomycetes, especially cups, terrify me. There are so many that look macroscopically identical

Pleurotus sp, aka oysters. Spore print won't really help here, most things that look like this are white-spored or near. Think of spore prints as a way to occasionally rule out something else, not mandatory for a positive ID

To your second point, no they don't. Coprinus comatus does not contain any benzocoprines, and does not interact with alcohol. Coprinopsis atramentaria is the one you are referring to. Completely different genus - and not one I'd recommend eating anyways, besides the alcohol interaction they have been found to cause testicular lesions!

Other fungi

Compare to Pleurotus, growing from buried wood. The ones to rule out here would be the worrisome Clitocybe dealbata group
