Good questions: I did not save the specimen and I don’t remember it from 14 years ago. The habitat looks like Madrone and Red Alder.

Problem is that one species is active and the other is not.

Panaeolus acuminatus (Syn.=Panaeolus fimicola) is not an active species while Panaeolus olivaceus Mol. is an active species. Sten, check your spelling of the species. And caps have a wice varience in their sizes, shapes and coloration.

btw, Panaeolus olivaceus is not mentioned anywhere in Paul Stamts’ Psilocybin Mushrooms of the World

HI Sten:
Please use the Propose Another Name button to suggest a different name. That’s how MO is intended to work. It helps drive the consensus to the best name, and it enables features that aren’t enabled by merely leaving a Comment (e.g., searching for Observations where a Name is proposed).
(Of course, you’re free to also add a Comment.)

I vote it is Panaeolus olivaceceus Møl.

The cap is very light for P. fimicola (Lge.) Kühn. & Romagn, wich is not really hygrophanos and has a somewhat darker stipe and cap-margin normally bended down, not outwards.
