I looked back through my photos from 2009.

I found the photo showing this mushroom in situ, and I found the spore pic. Although the resolution is insufficient for MO zoom, when I enlarge the photo on my computer it appears some of the spores have lengths around 10 mu, maybe even slightly longer. This supports the flavorubens proposal. It’s difficult to determine if the small dark area on the stipe base is staining of the context or just a little dirt. Otherwise, there appears to be no staining on the context.

I know the spot where I collected these.

Thanks David,

as described in Phillips fits this very well… except maybe for the lack of volval remains on the cap. They may have washed off during a heavy downpour.

I think that Noah nailed it.

bright yellow cap color, slight bulb, slight reddening at base, amyloid spores all point to flavorubens.
