Well the spores

aren’t too different, so that doesn’t help much.
Don’t know what to say. I bet it was L. magnispora, and these look like they,
but maybe somewhere there exists evidence to the contrary? Shrug.

A memory about this particular one

I see the observational points your making, consistent with other images on MO. But I do want to add that my memory is that this particular specimen was handed to me with specific instruction that the spores had been scoped and that Lepiota spheniscispora was the correct ID. It was why I made the note at the time of posting about “microscope work may follow up…”. (it never did). After photographing this I returned it to its identifier (a person you know very well) with the impression that it was going to be taken back to Berkeley for further study.
