small slender specimens of A. bisporigera. Stature seems to vary considerably with this type.

Here’s a nice example (not my collection).

I think these were only a few inches high, 3 maybe?

shows a limbate volval sac with long limb appressed to the stipe. For the time being, I think there is no better available species name for this mushroom.

As you can see on last picture, “The volva is membranous, white, sometimes taking on a pinkish tint at maturity, arising from the upper surface of the bulb, limbate, and usually collapsing against the stem base” right?

Need better shot of the base/volva

How tall were they? Look like A. bisporagera, but can’t see if they have a really large cup.
