I’ll see what I can find about these varietal names. Off the top of my head, the odor of this collection being very slight seems to lead away from “var. fragrans.”

I’ll take down the original proposal and replace it with “H. pudorinus group.”

the stipe surface yellow. This also occurred on the cap surface. In fact, KOH/yellow on the cap was more prominent than on the stipe.

Gills were pale pinkish, as seen in the photos. That was what led me in the direction of pudorinus in the first place.

Habitat: under a large White Pine growing on a lawn.

KOH Yellow Staining

Was this just the granules or the stipe cuticle itself? If it was the cuticle then I would say you have something else, maybe an undescribed species. The stature reminds me of H. chrysodon and there is a form with white granules but the gill color is described as white or cream. These are pinkish on my monitor.
What was the habitat?
