Walt’s 139064 in the ITS region. I now have sequenced collections of this variety from OH, NY and NJ.

Thanks Debbie .. cute little guys aren’t they.

Yes the cystidia are in “florets” of sorts. Very hard to tell on my dried herbarium specimen, but I think they are at the lamella edge. I’m not totally sure. I find precise sectioning a dried specimen this tiny very hard. I should have done it when it was fresh.

As you see, I’m slowly uploading my many Inocybe collections. I probably need DNA work to make any sense of these.

stunning photo, Linas.

But I have no opinion as to its ID.

Were those cystidia in clusters?
