It is unusual to see a lepidella…

with a membranous covering on the volva left on the cap, and to have to fragment(s) of the membranous volval layer left on the bulb margin. Perhaps, there would be such fragments in other specimens of the species.

Very best,

The volva is very interesting in this mushroom.

It appears to have a thin membranous external layer and to have split through an internal layer along vertical cleavages. This suggests that the inner layer has elements (hyphae and inflated cells) with strongly vertical organization. That’s probably not a known species.

Very best,

This material appears to have contracted the yellowing syndrome.

This syndrome is discussed on the WAO site with regard to its appearance in A. subsolitaria:
