Observation 168062: Amanita “sp-T01”
When: 2014-06-16

Notes: Found in the northern part of the Turkey Creek Unit of the Big Thicket National Preserve.
Caps up to 5.0 cm across with striations up to 4 mm long.
Spores were ~ 9.0-12.5 X 8.2-12.1 microns, globose to subglobose.
Q(range) = 1.00-1.10. Q(ave) = 1.04.
I’m tentatively using Rod Tulloss’ Amanita sp-T01 as an ID, but ready to yield to any more informed guess.

I checked the status of sequencing on this collection. It’s in a very large batch that is being sequenced presently; so maybe I’ll have some news earlyish in the new year.

Very best,


Thanks Ron,

This material has been received and accessioned to Rod’s herbarium. We have scheduled it for DNA sequencing.

It will be fun to see if I’ve learned enough to put a name on this one “at sight.”

Frankly, I don’t feel very confidant.

Very best,


Will do Rod.

At first, I was concerned because there was no gray or black ring on the lower stem.

Then I saw what appear to be gray fragments of volva sticking out from the undersides of the two stems. If it’s not “sp-T01,” it seems it might be very “close.” I would like to see a portion of this material if that is possible.

Very best,
