cap The cap of Amanita sp-N35 is 91 - 124 mm wide; it is pale cream and ovoid at first and, in age, becomes olive-cream with a brown disc and broadly campanulate with a broad umbo.  The cap is viscid when wet and otherwise tacky and dull.  The flesh is white.  The margin is striate.  No remains of the volva are usually found on the cap.
gills The gills are free, crowded, and white both in mass and in side view.  They dry an orangish pink.  Short gills of this species are truncate, of diverse lengths, plentiful, and unevenly distributed.
stem The stem of this species is 118 - 188 × 14 - 17 mm, has a white to pallid ground color with some regions pale orange fading to pale ocher, and rapidly becomes gray from handling and becomes gray from the base upward in age.  The surface is pulverulent to punctate in the upper third and fibrillose below.  The stipe decoration is at first the same color as the base/ground color.  The fibrils eventually turn gray to black.  The stem's flesh is very firm, white, unchanging when cut or bruised, and hollow.  The saccate volva is white, smooth, soft, and membranous.  The 40 - 50 × 24 - 28 mm sack.  The volva's internal limb is placed quite low on the inner surface of the sack and small or merely shelf-like.
odor/taste there is no detectable odor.
spores The spores measure (8.5-) 9.5 - 11.8 × (8.2-) 8.5 - 10.2 (-10.5) µm and are globose to subglobose to broadly ellipsoid and inamyloid.  Clamps are probably absent from bases of basidia.
discussion This provisional species is known only from Middlesex Co., Connecticut, where it was found in a small group in the fine loam of a mixed hardwoods forest that included Oak.—R. E. Tulloss
