Notes: This type silvery-gray amanita appears in a few different areas of my lawn (at least I think they are all the same type). “Old species 17” has been suggected as a name that may apply. This one was collected in an area where I have seen only a few of these over the years. Stipe base/volval buried in the soil. With care, I was able to extract most of the fragile volva.
The one common feature among the areas where I find nthis type is the presence of Shagbark Hickory. This specimen was collected from my lawn in an area deviod of oak… not even any seedlings. Hickory, walnut, and maple are the dominant tree types in this area. Another area wgere I find this type on my property (lawn) features a few oak saplings. The most prominent tree in this area is a large Shagbark Hickory. So I’m wondering if this may be a hickory associate.
Looking through my records, I am surprised to see that I haven’t photographed spores from more of these collections. This type amanita generally first appears in June and fruits through August. Spores from this collections are broadly elliptical.
I’ll dry this one.

This material has been received and accessioned into Rod’s herbarium.
I agree with your assessment of this material. I have the same species (I am quite sure) on my lawn under a solitary Pin Oak. It is also on the grounds of the Public School in Roosevelt under Pin Oaks. The fragile volva that easily detaches in the substrate is typical of our material also. The spores also appear to be very similar. I have repeatedly found it on lawns with oaks. On the other hand, we have plentiful Hickory in the woods in town (several species); I will try to keep an eye out under the Hickories.
