I did split them to dry them

I’ll get a shot of the bulb tonight for you. I agree about the apparent striations — the cap on that one was pretty dry & the skin on top seemed to be slightly transparent.

It seems that there may be a bulb on the stipe base. It looks as though the bottom of the stem (as far as I can see) is beginning to curve outward into a subglobose bulb as it disappears behind the curtain of the volval limb. In this case we cannot ignore what is “behind the curtain.”

The short gills are truncate and there are short striations on the edge of the cap. Normally this would point toward possible assignment in section Caesareae; however, the edge of the cap is clearly drying which can produce very short striations in species that normally do not have striate caps. Truncate short gills do occur in common species of sect. Phalloideae such as A. bisporigera. (Possibly? a character retained from a common ancestor with sect Amidella, which is notorious for its containing amyloid-spored species with truncate short gills.)

Is it too late to ask you to cut the stipe longitudinally so that we can see the shape of the bulb inside the volva?

Very appreciative of your efforts,

Rod
