Collection location: Pikes Creek, Pennsylvania, USA [Click for map]
Terrestrial near two Red Oaks. Yellow colored caps with pinkish-brown discs, and yellow superficial scales on caps. Context yellow under the pilepellis white below and no noticable reddining of context. (staining does not always occur according to my research). Pileus diameters were 6-7.5 cm with a height of 22-25 mm. Margins were straight to the stipe, then parallel to it. No stiations on the appendiculate cap which was dry and dull. The context was 7mm at the stipe, curved upwards then downwards and was 1mm thick at the margin.. Flesh fragile, broke easily ,but the cuticle held the pioeces together. Lamellae were white in all views, 5-6 mm broad,subcrowded, and finely attached. They curved upwards to meet the stipe. The lamellulaelooked like there were four different lenghts. The stipe seemed to bruise reddish slightly, was 65-70 mm from pileus to the bulb, and 9-14 mm at midstipe. The bulb was 30mm long and 20 mm wide, rooting , white with perhaps yellow fragments of a UV, and appeared to have minute fibrils or tiny scales on it. Stipe context white, solid with pinkish worm holes. Partial veil left a superior annulus on the stipe, but this was inadvertantly removed in handling it. Spore photos on bottom. At 400x each occular ~ 2.4-2.5 u. At 1000x each line ~1 u.

I should have read all of your notes.
Pinkish worm holes is a good indicator for flavorubens/flavorubescens (same species).
what you may be reffering to are the pinkish worm holes present in the stipe regarding my notes. Also in zoom you may see red staining on the stipe. In any event remind me not to eat it.
But the one place where your chances are best to see the rubescence is inside the stipe base. From the Amanita Studies site, " …interior of the bulb is often the place where wine-red staining first appears intensely." I have observed specimens where staining is observable only in the stipe base.
The shapes of the stipe base in this obs fit well with flavorubens.
Actually, I think I see the rubescence in the stipe base seen in the photo. Zoom appears to show a thin dark area inside the break.
the flesh of this species has less of a tendency to stain reddish, and somtimes this reaction is entirely absent.
is to break/slice a small potion of context from the stipe base. The interior of flavorubens usually shows a little reddish brown discoloring.
