From the images, I’d say you didn’t dig down 6 inches or so.

You’d have to dig down five inches or so two show the top of the volva of the Maine material.

I’m pretty sure you have something different.

Very best,


Were the upper parts of the limbs of the volva originally exposed…

about as shown in the second photo?

Amanitasp-N63” has the base of the stem about 150 mm below ground. None of the volval sac would be showing in that case.

Very best,

was not visible at first; I dug it out for the lower photograph.

If you see something like this again and can dry it for later examination,…

I would be very interested in seeing some of the dried material.

I can see some differences with regard to “sp-N63”: The marginal strations of the cap are much longer in proportion to the cap radius than in the Maine species. Also, The ME species has a great deal of the stipe buried below ground. In your case the top of the volval sac is visible at ground level. I think this could be a significant difference. I would not propose “sp-N63” as a name for this collection.

Very best,


I haven’t been able to get an illustration on-line yet and am stilling working on text.

This looks a lot like Amanita “sp-N63” of which the original collection was recorded on mushroomobserver in observation #25246.
