representing section Validae are amyloid; section Amanita, not amyloid.

I’d say “I’d call it that” (flavorubens) for the yellow one that’s laid out in the first two pics. The orange one is kinda provocative… although, I just checked http://www.amanitaceae.org/?Amanita+flavorubens and RET mentions “dark orange brown” within the range of cap color for flavorubens. So, I’m upgrading my vote.

Nice observation, Chris. Indeed, sometimes an ambiguity observed in an amanita I bring home motivates me to sacrifice a drop of Meltzer’s. In this case, I had originally considered potential confusion with muscaria.

What are you referring to regarding Melzer’s with respect to Section Validae vs Amanita? Are the spores of one section amyloid whereas those in the other section aren’t? Wouldn’t the rubescent discolorations be enough to determine section Validae?

Probably all A. flavorubens.

I try to keep some Melzer’s on hand for potential Validae vs. Amanita situations like this (easier said than done, in the past I’ve gone without).

The orange cap color is provocative.
