Used references: Mushrooms and other fungi of North America, Roger Phillips.
Based on microscopic features: The triangular spores seem like they should be distinctive. M. nigripes has triaular spores but the stipe is described as being much shorter. However picture #1 in the Audubon field guide shows longer stipes.

You got a spore shot! Nice! I was wondering about a spore shot for this species, that is a good thing to have for the site. This have fairly unique spores, and actually was moved to another genus. I’ll update the species listing to point to the new genus, so this can get listed next to other obs.
