Notes:
Habitat: oak woodland
Substrate: duff
Cap: 5.7 cm w; convex; context 9.5mm thick; context pure white did NOT discolor with handling or cutting; cuticle white w/reddish brown discoloration, concentrated heavier toward the center; medium size chunky white warts; appendiculate; odor very mild, indistinct, i.e. I can’t really smell anything
Gills: ivory white, adnexed
Stipe: 7.5 cm h; 2.5 cm thick right above the bulbous base tapering quickly to 1.27 cm at the top; base 5 cm h x ⅗ cm at it’s widest point near the top (of the base) tapering to a point, approximating the shape of a triangle; solid; remnants of an annulus could be seen with striations at the top of the stipe; odor indistinct; white with brownish red discorations on the exterior; it didn’t have a cup like volva, but there was an edge at the top of the base, but it was barely separated from it (see detail photo).
Spores: ? Waiting for spore prints
Notes: When I found this it had probably been handled or bumped into (by a human or animal); I found it with the cap next to the stipe. All parts discolored very little with handling; the mushroom was overall white with reddish brown discoloration on the cap and brownish red discoloration on the stipe, i.e. the stipe discolorations were more red toned, and the cap discolorations were more brown toned.

The discolorations toward the bottom were noticeably more red toned than the discolorations on the cap.
Stipe very pointy at the bottom and tapered at the top
Pure white context did not discolor with cutting or handling

No red bruising or discoloration

I keyed this out, and was led to A. novinupta. It is very similar, except the descriptions I’ve read (at least 4-5) mention red bruising. I handled this extensively as well as cut the stipe and cap with a knife. There was no bruising or discoloration caused by it, nor was there any discoloration of the freshly cut surfaces with exposure to air. The gills, cap context, and stipe remained white. The only color was the color that was already present when I found it. Also, the descriptions involved of the stipe & base didn’t match the typical description. The stipe had a dramatic taper and was 1/2 as thick at the top as at the bottom just above the volva. The volva lacked any rings that are mentioned in descriptions of A. novinupta.
