gills The gills are free, whitish or slightly sordid, and about 3.5 mm broad.  The short gills are truncate and irregularly distributed.
stem The stem is about 40 × 2 - 2.5 mm, white, minutely striate lengthwise; and has no annulus. The volva on the stem's base is white on the outer surface, sack-like, membranous, about 8 mm high, and connected to the stem just at the stem's base.
spores The spores measure (7.9-) 8.1 - 10.5 (-12.0) × (6.0-) 7.0 - 9.3 (-11.0) µm and are globose to subglobose to broadly ellipsoid (rarely ellipsoid) and inamyloid.  Clamps are not to be found at bases of basidia.
