Similar habitat as the Leratiomyces in your other posting ... another wee dark-spored grass/mulch inhabitor. It looks a bit like a Panaeolus, but there are other possibilities. If you are keen to know for sure, this is the season of mushroom shows, so you could bring your specimen to the one on October 30, 2016 in your area. 2016 Fall Mushroom Show | Oregon Mycological Society cheers, frog
