Based upon the small amount of info I’ve seen…

I believe that C. sistrata and C. seminuda are synonyms. Arora calls this type Lepiota seminuda. I haven’t seen any info on cystidia for this type.

Round cells

The round cells were found on the stipe and the pileus and I think (?) they may be a feature common to some or all or at least a few Cystolepiota that account for the “dusty” appearance of the cap and stem. I am not familiar with C. sistrata I will look into it Thanks Dave!

Edit: more info, I did not find Cystidia when looking at the gills on this specimen. Globose cells are mentioned in the description for Cystolepiota seminuda as well.

I have never collected a Cystolepiota,

but this obs seems like a bullseye to me. The round cells – presumably taken from the cap cuticle – are mentioned by Miller as a defining character for C. sistrata. MO has an obs of C. sistrata found at last year’s NAMA foray in PA. So this mushroom is known from eastern NA.
