Observation 141816: Amanita jacksonii Pomerleau

I found this species in this same location last September after a long, hot, dry summer. We had a huge week long rain event then, and afterwards 5 huge rings of A. jacksonii appeared.
You can find that entry under MO 111332. The photos do not do them justice.
Unfortunately I did not save a specimen then, but I picked a unique one this time and tomorrow it will be on its way to Dr. Tulloss.

Today I found two partial rings, once again associated with mature White Oaks.
The squirrels and three toed box turtles, along with beetles and their larvae just love them!!!!

Have a great day!

Without people like yourself, there would be fewer results of the work and less new knowledge to explore.

Hence, thanks to you, too.

Very best,

“sp-S10” does indeed look very similar and I see that my good friend Patrick Harvey has found a sample a few counties to my northeast.
in the technical tab of the link you provided it is mentioned that the samples where immature/old and or stressed, I am hopeful that the several mature specimens I sent you will be helpful.

thanks for the update on sp-MO01
and thank you for all of your hard work!!!

As to what the species may be, I suggest that you take a look at Amanitasp-S10” here:


The photographs of “sp-S10” seem very similar to your photographs with the present observation.

As to sp-MO01, it is amazing the coincidences we’re running into this morning. Santiago and I were just talking about it! He has some sequences, but is hoping for more to clarify the amount of genetic variation within the species and help suggest possible genetic relationships with other taxa. From my viewpoint “sp-MO01” is a distinct taxon. So far, I don’t hear a contradiction coming from molecular results.

As you observed, it is a question of patience and more material. :) :(

Very best,

The wheels of progress move slow, sometimes even slower!
I was just curious about this one as I am currently still refereeing to it as A. jacksonii as there is nothing else listed that even comes close.

Since I have you on the hook so to speak, any word on Amanita “sp-MO01” Tulloss nom. prov. MO 111182 and MO 110108?

Thank you and have a great day.

What a coincidence. I can actually tell you a precise status.

We just got a request from Santiago Sanchez to repeat our sampling of your material. We believe we will have the sample in the mail tomorrow or Saturday. Apparently something went wrong with the first attempt at extraction of DNA…sounds like an error in the lab from what Santiago said. Naomi will be in tomorrow along with another person and your collection is on the agenda.

Santiago is working with multiple gene sequences in his work on the Caesareae; so I hope he will be able to get all he wants/needs from your material.

Very best,


DNA results?

The anticipation is killing me:)

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

Not A. jacksonii??

This is very interesting, cause if it is not, then the question bears asking; what the heck is it?
It will be exciting to see what you determine.
Specimen is on its way!

And thank you for your work!

Thanks for drying the specimen.

I’m still inclined to believe that this is not jacksonii. I have sent out samples of material very like this for DNA sequencing, but I’ve not heard back on the results as of this moment.

Very best,
