I now think I understand the “beveled” thing. It’s about the abrupt change in shape of the outer part of the cap. I had been under the impression that it had something to do with the way the cuticle meets the pore surface.

I did get the pale yellow KOH reaction on the context. That’s the main reason why I had initially favored “ferrugineus.” To make matters even more confusing, this collection lacked the sweet badiceps odor.

KOH should stain the context of B. ferrugineus pale yellow. However, the cap edge of the larger basidiocarp in the first picture is strongly beveled or chamfered. Apparently, this characteristic is unique to B. badiceps. The cap color, as noted by Noah, also suggests B. badiceps.

just about to add “badiceps” as an alternative proposal, and you beat me to it, Noah! I’m a bit confused about the “beveled” cap margin thing.
