We have received the DNA sequencing data from the voucher of this observation.

As usual for the species, we have a fragment of nrITS with several ambiguities. We have a very good nrLSU. The species is Amanita audubonensis. This is a nice collection of a newly recognized species, and I am very glad that you shared it with us. It was very helpful in determining what part of nrITS are relatively stable and which regularly exhibit ambiguity.

The pictures are also helpful.

Thank you for sending the voucher material to us.

Very best,

The voucher material for this observation has been accessioned in our herbarium.

Thank you very much, Alexei, for contributing portions of your 2018 collections to the Roosevelt herbarium and our research.

Very best,

They could even be three different species because of color differences in the zonation.

On the other hand, the coloring could be variable. There are so many zonate-capped Vaginatae, that I don’t like to make decisions with further examination of the material. Working with the Vaginatae is a challenge. Working with the zonate species is a bigger challenge. It is possible that the color pattern has evolved two or more times in the history of the section.

Very best,

description of battarrae, the cap colors are shades of ash-gray (cinereus).

My impress ion is that we don’t have battarrae in North America.

The zonate cap on your material is very striking. I have never seen this paticular color combination.

Very best,

I am truly surprised by the diversity you are finding within the Vaginatae. This is another striking specimen. I don’t think I have ever seen this species before.

Can you spare part of a dried collection?

I’d love to learn more about this one.

Very best,

Rod Tulloss
