Observation 137218: Amanita “sp-F11” Tulloss
When: 2013-06-21
No herbarium specimen

Notes: I already have an observation for this species, and I have already sent samples to RET, as of now it is still not identified.

I found more of these today and wanted to keep track of all the pics.
Thus the reason for making a duplicate observation of the same species.

Thanks again.

Very best,

Thanks for sending this one.

It will be scheduled for sampling in the near future.

Very best,

This specimen has been received and accessioned into Rod’s herbarium.

Boy, did I make a lot of typos in that post. How could you even read it?

Yes, I think the recent spate of species of the Caesareae with bright color on the cap (generally yellow with red in the center), and white stem with white partial veil, etc. all are one taxon. But I have not had the time to do any microscopy on the material. [I find the organizing the flow of material through my home labs is a very big job right now…and I have great people helping me.] I’m thinking that you all may have found the southern most populations of Amanita sp-AR01; however, that’s a flat out guess.

I find the Caesareae very beautiful and am glad to have been able to play a part in helping to organize the undescribed species in North and Central America and a few other places.

Dr. Moncalvo and various students have been working on the Caesareae genetics on and off for about a decade. During which time I have passed to them many collections of a large number of species for which the vouchers are deposited in my herbarium. One of the forces that moved me from purely working on morphology to taking actions supportive of work on the genetics of the Amanitaceae has been the interaction with Santiago and with other persons that I’ve mentioned on MO such as Dr. Zhuliang Yang in Kunming and Dr. Jozsef Geml (now in Leiden) and Drs. Karen Hughes and Ron Petersen in Knoxville.

Dr. Tom Bruns at Berkeley has been very supportive of our work in Roosevelt and on the WAO site. He has played a leading role in the proposal of a North American Mycoflora Project. As I have written before, I am concerned about the future of morphological studies in mycology. I am worried that the skills will die out before any methods of the future (like the smell-o-tricorder) exist. This concern is reflected in the proposal of the North American Mycoflora project (currently unfunded and only a proposal) in the following way: They intend to promote the connection of currently applied names to gene sequences…relying heavily on the contributions of volunteer “citizen scientists”…namely us, the unpaid eyes, hands, and minds of contemporary mycology in North America.

It is an awesome thought that we folks could drive science forward through getting our hands dirty (plus a lot of learning, a little intelligence, and some good sound methods).

It is an interesting and challenging time.

A slogan: Sequence the genes, and remember, study, and conserve the organisms!

Very best,

Rod

Awesome!

RET that’s simply awesome… Timethyl- great photos as usual!!!!

Are these the same species that I’ve been finding about 4 hours south of Timethyl?

cause they seem a little different…

I will tell you in more detail what is happening with regard to the Caesareae.

A colleague from Mexico (Santiago Sanchez) is studying at a well-established phylogenetic laboratory in Canada that is headed by Dr. Jean-Marc Moncalvo. The work has reached the point where a paper related to sect. Caesareae genetics has been drafted.

The research will continue after the publication of the initial paper. During the work leading to the first paper, many species of section Caesareae have been studied (when possible, multiple genes). The species are from all over the world, but the collection is especially strong for some regions (e.g., North America and Central America).

During the period of wrap up for the first publication, sequencing of new samples is continuing. I have been gathering material from as many sources as possible and shipping it to Santiago. It has been a great opportunity for me and my colleagues in Roosevelt (Cristina and Naomi) to be able to work with Santiago and Dr. Moncalvo.

MO has been a very good place to see a diversity of undescribed species of sect. Caesareae…especially in the last two years.

I expect that, within weeks or months, we will know if your material falls into one of the taxa that is becoming known through the morphological work behind the WAO Caesareae pages and the work of Santiago, his professor, and his colleagues in Canada.

Many collectors have contributed and are contributing to this developing research. The volume of data and the geographic coverage of the study would be significantly less than it is without the collaborations of the collectors.

MO is playing a valuable role bringing us all together in support of Santiago’s project and for many other studies.

If you look at the technical tabs of species of sect. Caesareae, you will see that many sequences (represented by their GenBank numbers) for material from the Caesareae have already been obtained by Santiago et al.

I trust that if DNA can be extracted from your material, your collections will appear in the lists of sequences studied in research supporting future articles and will appear as GenBank accessioned sequences on the WAO site.

The above is just the story of the genetic studies in the Caesareae. There is much else going in the study of Amanita at present. It’s a very enjoyable time to be an “old” student of the Amanitaceae. Things are hopping all over the place.

Very best,

Rod

Thank you once again

I look froward to any headway we can make with this collection.

This is not a described species.

The question that we’re trying to settle is “Is this one of the species to which we have already assigned a code number (e.g., Amanita sp-AR01) or is this something new?”

I’m quite confident that I can’t give you an already existing name in this case.

Very best,

Rod

They look like candy…too beautiful to believe.
