It does look like Cystoderma here. It doesn’t look like you have cystidia. There aren’t many Cystoderma (or more Cystodermella) that have cystidia, and they will be pretty obvious. You can see one here, from New Mexico, so similar habitat:


And there is a shot of the cystidia there. I also saw another Cystoderma there without cystidia, which you can see here:


Still not completely sure about species, I put a ref. there for further research, if you want to through that paper, and see how it compares.

No reason I can see it couldn’t be Cystoderma amianthinum without checking the average spore size and spore amyloidity. The color is more fitting.

I don’t see anything in the micrographs that looks like cystidia. Cystidia is absent in many white spored genera, and present in roughly half of the Cystoderma. The pileipellis pics agree well with Cystoderma.

may have been present. any structures I was able to find at the gill edge were very few and far between (see bottom-most photo).
