My old 400x scope often fails to show presence of spore ornamentation. But the spores do otherwise look like from a Cort. Interesting species…? Spore print color unusual for a Cort (light brown).

It’s a Cortinarius …

I scoped it and the spores are finely textured in the typical Cort way.

I thought it was an Entoloma.

Zoom on spores shows some with nucleus (oil drop?) of different color, something I do not associate with Inocybe. Spores seem unifomely elongate elliptic for Inocybe. Usually I find a few bean-shaped spores for the “elliptic spore” types. Rooting in humus seems a bit odd for Inocybe. No noticable odor.

Spore print color, some macro features, and availability of other Inocybes (during a time when few other genera were represented) support the Inocybe proposal. I’ll reduce confidence on my “Agaricales” and maybe Linas Kudzma will notice the “Inocybe” post. I have the dehydrated cap.
