The stem is "white," and the volva at the stem's base is sack-like, white on the outer surface, and sheathing.
spores
The spores measure (10.0-) 10.5 - 14.0 × 9.0 - 12.6 µm and are subglobose to broadly ellipsoid (infrequently globose) and inamyloid. Clamps are not to be found at the bases of basidia.

discussion
Evaluation of spore volumes indicates that 2-spore basidia were present; hence,
values above are probably high for an average mature specimen.
Removing the measurements representing the three largest spores from the data
would yield [17/1/1] (10.0-) 10.5 - 12.9 (-13.3) × 9.0 - 11.5 (-11.6) µm,
(L = 11.4 µm; W = 10.2 µm; Q = (1.03-) 1.05 - 1.21 (-1.29); Q = 1.12). If another collection of this material were found with mature fruiting bodies, their spores would probably produce summary data more like those provide in this paragraph.

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer;
and explanations prepared for this site talk about specimen-observer pairs associated with each data set.
Combining more data into a single data set is non-optimal because it obscures observer differences
(which may be valuable for instructional purposes, for example) and may obscure instances in which
a single collection inadvertently contains a mixture of taxa.
