I could be josserandii from the discriptions of the species. But it is on the small size for the range of discriptions.

But it is right in the middle of the discriptions for spheniscispora (ref. in the comments). The clear difference would be in how eliptical the spores are, but I don’t have a microscope. But since spheniscispora is found in the bay area, and it is closer to center of the discription, I’m going with that.

Probably – looks like it alright

Looking at the descriptions of the two mushrooms, it could
be either really. But the size is in the middle of the
spheniscispora, and at the small size for the josserandii.
The one clear difference between the two would be the spore
size, the spheniscispora spores are 3-4 to 1 elliptical,
where the josserandii is 1.5-2 to 1 elliptical. So, if I
had a microscope I could tell, but oh well.

I guess since the size is in the middle of the range, and
the habitat is right, go with spheniscispora.

Thanks for the reference, hadn’t seen that.

Lepiota spheniscispora?

This looks a lot like Lepiota spheniscispora. You might have rejected that species already, but there is a description and photo here here .
