Notes: Found in the Turkey Creek Unit of the Big Thicket National Preserve.
Cap 6.6 cm across, sl tacky with striations 12mm long.
Spore print white and spores not amyloid.
Spores ~ 10.0-14.1 X 7.1-10.0 microns, mostly ellipsoid.
Q(range) = 1.27-1.52. Q(ave) = 1.37. n=21
A rather drab specimen but with large spores.

This material has been received and accessioned to Rod’s herbarium. We have scheduled it for DNA sequencing.
I’d say that half the stem was underground.
Yes, I’d like to see this material.
and in the sandy and rooty soils of most of the Big Thicket, I find most of the Amanitas are buried fairly deeply and difficult to extract cleanly. Can’t recall exactly how deep this one was.
May I assume that this one is interesting enough to include in my next care package?
While we don’t have enough data on the likelihood of Texas Vaginatae having half the of the stipe below the surface of the soil (my guess is that the probability is pretty high), we do know that “sp-S01” will do that.
It could be the volval sack is playing games with my eyes; however, the base of the stem looks as though there might be a bulb there. Of the species in our list for Texas and the Gulf Coast sp-T44 has spores of appropriate length; the the spores are subglobose rather than ellipsoid (which you report). So, if it’s in the Vaginatae, we haven’t recorded it previously.
The deeply buried stipe and the apparent bulb, suggested to me that it might be pale material of A. “sp-S01” (sect. Amanita); however, I would have expected slightly higher Q for that species.
So I’m puzzled in either case. I’m very curious to know if there were a bulb.
