I’m sorry to say that we are backlogged.

Your material has not yet been accessioned into our herbarium. My guess is that we are backlogged several dozens if not a hundred or more collections from a very busy season. We are working hard to catch up; however, Naomi can work at most two part days per week during the school year. We will get to it. Naomi usually posts on MO when she has completed the accessioning stage for a collection.

We are hoping to start moving through the sequencing of our collections of section Vaginata within the month. This will take a long time, I think; however, our hope is to provide the best set of data genetic data for Amanita sset. Vaginatae that is preently available…even though it will (inevitably) be incomplete.

Very best,


Any updates Rod?

I think it’s all shale underneath the soil in this area.

Thank you, AJ.

If it does turn out to be williamsiae, then it will be the first specimen that I have personally seen fresh or dried from outside of a sandy, Atlantic coastal plain habitat. Is the area from which you report this mushroom sandy below the organic layer of the soil?

Very best,


Overall Height is ~ 170 mm

Hello Rod,

I thought you might find this one interesting; I certainly did! I believe the bottom of the stem is complete, because I popped it out of the ground from underneath rather than plucking it from above. I’d be happy to send this specimen to you for further study. This was collected streamside in an area dominated by beech and hemlock, though there may have been other trees present as well.


Hello, AJ.

This looks very nicely collected. Can you estimate the overall height of the fruiting body?

If the bottom of the stem is complete (looks like it), then this is either A. williamsiae or a new one on me.


I’d very much like to see the dried material if you can spare it or a part of it.

Very best,
