We have received this material and accessioned it to Rod’s herbarium, It has been scheduled for DNA sequencing.

Updated smell.

It definitely smells fishy now.

I have seen the BAMS velosa page before, but I didn’t notice the two with indistinct volva, thanks for pointing them out. And it is easy to leave the volva in the ground when digging them up (If that is what you meant?), so I usually spend a few to several minutes digging Amanitas out carefully with a knife. This one came out relatively cleanly and easily.

And either way, I am drying & saving the specimen so it can be viewed under a scope later. I recently made the plunge and ordered one online, so it shouldn’t be too long.

yes, a “normal” velosa specimen has a membranous volva…

but I have left those in the ground before when digging them up; check out the BAMS velosa page, where I show two examples of a velosa with an indistinct volva, one in the group basket photo, and the other with its volva riding far up the stipe (and leaving a crumbly, non-membranous covered base):


all conjecture at this point, other than it being a vaginate amanita.

The base smells possibly faintly fishy, too soon to tell quite yet though. I left it out to see if I can enhance the smell and will update later. And wouldn’t a white A. velosa have a cup-like volva like the non-white ones in observation 64890? http://mushroomobserver.org/64890?q=3zH1
Rather then an indistinct volva as this Amanita has? (I’m certain I dug it out in one piece)

could be a white velosa.

does it smell at all fishy?

It was white.

I checked this morning when taking a picture of the cross section to see if the striations were consistent. Which they are consistently faint and it was simply white under the veil. As for staining, it doesn’t appear to be doing so, neither red or yellow.

what was the cap color under that veil?

Gray? If so, this could be a protecta, with that crumbling volva at the stipe base. Has it yellowed or reddened since you collected it?
