Amanita in section Vaginatae.
I have 1 dried specimen but unfortunately I made very awful photographs for this collection.
This collection bears macroscopic characteristics similar to observations: 172163, 171619, 171624.
Such three observations below come from the same patches.
While this observaion was growing in the middle of a wood of young Quercus cerri/Quercus ilex 410,62 m distant from the other three said observations.
It is smaller but mature than other collected specimens.
Pileus siglthly umbonate even the photographs may not show it

seven of your collections. The accession numbers of the remaining six are RET 658-5, 658-9, 658-10, 659-5, 659-10, and 660-1.
At present we are working with two labs for sequencing purposes. The above collections are in the present list of samples to be made for sequencing. While I can’t be sure of timing (because our schedule has to be flexible), your remaining material will go out in the next planned shipment.
These are very interesting news, I will look forward making more collections and better photographs. Is this the only collection from me that matches this result?
This species is not one with an identified sequence in GenBank.
However it is one with an unidentified sequence in GenBank. Apparently, a sample of the same organism was collected as part of the mycorrhiza on the root tip of an oak in Germany.
I am trying to contact the authors of a paper that came out of the root tip sampling project.
When I find more, I’ll let you know. Our sequences will be sent to GenBank shortly.
..in either the UNITE or GenBank databases. We conclude that the taxon involved is a species of section Vaginatae that has not previously been sequenced with results shared publicly. Our nrLSU sequence which is attached to 10 characters of the 3’ end of nrITS is 1483 characters long…a substantial sequence. The 5’ motif of nrLSU has the TTTGACCTCAAATCA form. So the species in question is not part of the penetratix group. More later.
This material has been received and accessioned into Rod’s herbarium. We have scheduled if for DNA sequencing.

This Vaginatae has grey, umbonate, pileus (that’s awfully not viewable in the photograph) and a stem that is white and smooth. Volva remains at the base are white, with no particular warts or colored spots which cannot be explained by the soil, and its quite adherent to the stem and if not removed with the whole mushroom, some spare parts of the volva usually remain attached to the stem while if the basement remains buried it can last for days, it’s quite resistant in other words, but fragile.
Observation 171619 is very similar and can give you a better Idea of the specimen and the striations on the cap, 171619 way a little more grey, but it was highly more hydrated as only the cap was coming out from the moss, in this observation (172299) specimen was in an harder soil with no moss and very less humidity around. As said in the description also it is a Quercus cerri/Quercus ilex wood.And I can assure with a few margin of error that in this case is Q. cerri the host plant.
since your photos are admittedly not very good, can you describe what this amanita looked like? Cap color, shape of volva at base, relative length of striations on cap?
With oak exclusively, or in a mixed forest?
