The gills are free, crowded, and white, occasionally with a pinkish tinge; the short gills are attenuate.

The stipe is 80 x 9 - 14 mm, subcylindric or attenuate upwards, with a surface that is white; the stipe's basal bulb is 25 mm wide and abrupt to subabrupt.  The annulus is membranous, with an upper surface that is yellow to yellowish and a lower surface that is grayish to whitish.

The spores of A. citrina var. grisea measure 8.0 - 10.0 (-11.0) x 7.5 - 9.0 (-10.5) µm and are subglobose and amyloid.  Clamps are absent from bases of basidia.

Amanita citrina var. grisea was originally described from Japan.  It was recently reported also from southwestern China.
