Collection location: Smyrna Air Base, Rutherford Co., Tennessee, USA [Click for map]
82mm cap diameter x 160mm stipe length x 12mm stipe diameter. Sticky. 13 mushroooms in various stages of maturity scattered over about a 75ft radius in a grass field next to an airport runway. No trees near them. These seem to be a bit different than the ones I found in 2010 in the same vicinity, in that they are smaller in size, and have no odor. The 2010 examples had an extremely strong and unpleasant smell, unlike anything I know of.

…since we have confirmed your determination of A. thiersii for this collection. You will find that your info has changed from olive (not confirmed) to black (confirmed) in the material examined section of the technical tab for this species—> http://www.amanitaceae.org/?Amanita%20thiersii
After measuring 20 spores, your data landed dead-center of the other A. thiersii spore data. You can compare them by adding your data in the custom layer on the sporograph page http://www.amanitaceae.org/...
The data obtained collection* is as follows:
8.0-9.0 × (7.5-) 7.8 – 8.8 (-9.8) µm
Q = 1.01-1.06 (-1.16)
*The spores of the largest pileus were measured, and were found to be amyloid (a rather lovely dark translucent blue), adaxially flattened, with a narrow cylindric apiculus. Bilateral lamella trama confirmed as well as sterile lamella edge. The latter required close examination, as the inflated cells were minimal and floating away in reagent.

Thank you very much for sending it.
I realize I can use photographs on MO without asking, but I’d prefer to ask if I might select one or more of your images to use on WAO along with the geographic information, etc.
I edited the comment, but the original one was already winging its way to you. I happen to have the herbarium database on my laptop; and, when I checked for “Smyrna,” there was no material from the airforce base in the herbarium.
Your current plan for drying sounds interesting, I’ll report on the condition of the material when it arrives. Amanita thiersii tends to suck up water fromt he atmosphere after it is dried. I will expect slightly floppy specimens and get them in the dryer as quickly as possible. If you can keep them dry and mail them on Wednesday, I will return to home base on Thursday and may be able to get the mail that day. I will certainly get the mail on Friday.
I’ll send you some of this collection, but I can’t guarantee that you’ll be pleased with the quality. Not being a researcher, I don’t have any need for real drying equipment. I rigged up a cardboard box with a pan of silica gel desicccant and a computer cooling fan (no heat). It seemed to do the job, but it took about 36 hours. I’ll send them in the mail tomorrow. Let me know what you think and if it’s worthwhile for me to even bother doing this in the future.Cheers, Brian
I noted on www.amanitaceae.org that you had reported a collection from the air force base in the previous case. If you can dry some mature material from the present explosion of fruiting bodies, I’d be very appreciative. I would then have a specific collection from Tennessee that could be listed on the web site.
