Perhaps Mycena…

It looks like it could be a Mycena, but getting to species takes more. Arora isn’t very good for Mycena (or most small mushrooms), which he pretty much admits in the book. We should perhaps get together and try make a better key to CA Mycena, to id the ones you can by eye, of which there might be 20 or species. These off-white to grey Mycena through, not sure you can ever id by eye…

doesn’t have a gelatinous sheath on stipe

what makes me doubt that this might not be M. rorida is the lack of a gelatinous sheath on the stipe. However conditions have not been wet for the last few days.
