Collection location: Big Thicket, Hardin Co., Texas, USA [Click for map]
These were found in the southern section of the Turkey Creek Unit.
Wasn’t able to get many spores to drop and only measured a few, ~ 13. They were ~ 7.0-10.0(11.0) X 6.8-8.5(9.0). Q(ave) = 1.16.
The Q number is a little lower than what Rod has on his website, apparently due to the fact that these spores are slightly rounder than the average for this species.

also occurred to me.
However, they were all growing relatively close together.
I don’t remember which specimen(s) I got the spores from but they would not have been the sp-F11 type as they apparently have even narrower spores.
I did collect another group from nearby that was also more two-colored and sturdier. I did get a better spore print of those and will check them later.
I wasn’t able to save many of my collections, not having a suitable drier, but there were some other interesting unknown species, which I will post in a few days.
in the group of taxa mentioned belong to A. jacksonii.
A group of authors from Mexico, Canada, and the U.S. are currently working on a paper that will be accompanied by DNA sequences posted in GenBank for several taxa described and undescribed in the group of colorful Caesareae — like jacksonii. This will give us molecular information to apply in trying to sort out the yellow-orange-red group of Caesareae in the SE U.S….as well as many other parts of the world.
Collecting material with unusual pigment or pigment patterns in the cap, stipe, stipe decoration (limbus internus), or gills will be very helpful in trying to sort out what is going on the Caesareae.
The two caps on the right in the first photograph suggest Amanita sp-F11 because of the bicolor caps and the lack of orange decoration on the stipe. The same could apply to the third picture. The second picture has an apparently entirely red cap at the given stage of development, but the felted material on the stipe is not red-orange.
Amanita sp-F11 has been posted on MO from the area of Gainesville, FL, several times in recent weeks. We do know that there are at least four taxa of the jacksonii-arkansana habit growing in east Texas and along the Gulf Coast…maybe more.
