Recognized by sight: In my draft article on Amanita sect. Caesareae (Amanita Studies web site), this species would be long in the group I called Stirps “Pachysperma.” By the cap color, I’d say A. virginiana or A. subvirginiana. From what is known of the two species, A. virginiana (which is usually darker brown over the disc) is found in the northeastern US and A. subvirginiana is known only from Florida. The cap color here is a best match to subvirginiana. John, if you find more, please send several dried specimens. As far as I know, all three species mentioned occur only with oak. I’ve never seen a report of nearby trees that didn’t specify oak. Solitary oaks in cemeteries and arboreta seems to be good places to look for members of the group. They’re hunkered down low enough so that a lawn mower can miss them!

It grows in the cemetery right next to where I work. I will collect it if I see it again. It has not been up for a few years but I know the exact tree it was under and its been dry here for a few years. Hopefully I will see it again next year. I could also use some more photos.

It would be very interesting to see more pictures of the three taxa recognized in this group of very small (usually) species probably related to jacksonii. I hope MushroomObservers find more and post their pictures. Dried material would be very welcome. I published type studies on all the members of this group back in the mid-nineties. The species pages for virginiana and pachysperma are in pretty good shape on the Amanita Studies site.

Very best,
