I really do get the basic fact that opinions from those who know more than me are divided on whether bicolor is multiple species, a single species with massively plastic morphology, or some kind of “cloud” that will stretch our definition of what “species” means for mushrooms. Or even some fourth option that I can’t exactly put words to.

I fall into the several species + plasticity camp but (a) my opinion has limited value, (b) it’s more of an evidence-based hunch than an actual opinion, and © the one or two I feel firmest about may simply be pallidoroseus with a shade that is true red rather than pink.

The point is that careful study will give us actual data-driven answers, and careful observations will let us convert those answers back into useful field characteristics.

From memory, young ones pores darken and old ones stain more prominently. I am not sure about the stipe shape. This location has a profusion of this species which become olivaceous and rimose areolate and barely recognizable. I sent some to Ernst Both and he was puzzled but agreed with B. bicolor.

Walt, how does this version of bicolor bruise and age?

I find several variants on the bicolor theme and I’m not sure where this one would fit because it’s so young. Do you get any bruising on the pores at this age, or in older specimens? Will that bulbous stipe age into a straight pillar or could it remain with the rounder shape? Etc.
