Well, it’s certainly a Lepidella

The remnants of the partial veil (ring, annulus) seem to be between felted and floccose. A dense floccose layer covers the top of the stem. This can’t be A. cokeri which has a persistent, membranous, skirt-like annulus which sometimes is formed of two distinct layers joined (or not) at a margin thickened by part of the uninversl aveil (volva). The volval remnants on the cap of A. cokeri are pyramidal and rather EASILY LOST. The rings of recurved scales on the bulb in cokeri can also appear in other taxa of section Lepidella (onusta is one example). It looks to me as though the bulb of this species extended into an elongated “radical” or “root.” Was that the case?

I’m thinking of “A. magniradix nom. prov.” and A. rhopalopus as possibilities, but I don’t have much of a sense of confidence about these names.

It could also be a new species….maybe.
