The floccose material on the cap…

argues against A. polypyramis, which has plentiful pyramidal warts on the cap as the name implies.

WIth a volva on the cap that is so completely without warts, this implies that the structure of the volva itself lacks vertical ordering among its cells. This kind of internal structure to the volva would very likely lead to well-defined warts with distinct facets on them (i.e., looking like pyramids).

Disorderly universal veils are present in several groups of lepidellas that have members in eastern North America. Two examples that come quickly to mind are Bas’ stirpes (that’s the plural of stirps) Chlorinosma and Longipes. Your collection location falls into the known range of both A. chlorinosma and A. longipes.

The fact that your specimen is more “chunky” than either of these species might be due to the very high amount of rain we’re getting this year.
