Hello Erica.

The only species that is currently supported in the pileus is sclerocistidios Parasola auricoma . In your picture looks perfectly cistidios the pileus. Your examples are P. auricoma. To study the Parasola, no attention to the insertion of the gills, but yes in spore form and dimension spored. All the classification is based on this character.

Now that I’m starting to get into these different Coprinoid mushrooms a bit, I’d like to call this one Parasola leiocephala. The gills are pretty clearly free, which according to mykoweb.com, distinguishes it from P. auricoma. P. leiocephala also appears to be more common in the SF Bay Area.
