Good name..

Wondering if this one might be close; http://mushroomobserver.org/280515
Zoning is not as distinct but overall look seems similar to me(?).
It does lack however, the remnants of a non-ring, on the stipe.

Submitted ITS and LSU to GenBank via the portal.

Should have the accession numbers over the next few hours.

Will it be posted on MO?


We did find some others

About 30 species, the most interesting was Entonaema liquescens

Thanks for the effort. I hope you found some other things.

Bad News for this one …

Ha Ha Tonka area was without rain for the last 2 weeks. We did not find any Amanita there at yesterday’s foray. Sorry about that!

The proposed provisional name is intended as a noun in apposition.

This means that it is in the nominative case. No Latin ending is needed. Since hyphens are discouraged and blanks are not possible in species epithets, the three components of the name as usually written are strung together without breaks.

The species falls in Amanita series Penetratrices, which, in turn, lies within section Vaginatae.


The fact that about 10-15% of the Penetratrices have a more or less persistent partial veil suggests that the loss of basidial clamps may have preceded the loss of a partial veil in the early history of section Vaginatae. Of course, there’s some guessing involved in suggesting such a possiblity.

The first North American species of the Penetratrices with a partial veil was identified earlier this year (an observation on MO exists for this taxon):


A partial web page for __Amanita hahatonka will appear soon.

This collection has the accession number 622-6 in the Roosevelt herbarium. It has been listed for some time in a discussion of taxa in the provisional series that appears in the "discussion " data field on the technical tab of this page:


__Amanita hahatonka will soon be listed on the same page under its new provisional name.

I have read in an old-newspaper article dating from the origin of the state Park that “Ha Ha Tonka” means “Laughing Water.”

Very best,

where does the DNA fall out?
well within the Vaginatae or elsewhere?

Could you please put up the sequence here w/the obsie, and then we can all BLAST it!

Is that a ring on the stem?

Rod just took a look at this again and wonders if he sees a membrane partially appressed to the stem.

We have received good quality nrITS (“proposed barcode”) and nrLSU sequences from a sample of the voucher material of this observation that you sent us. Considering the unique pigmentation pattern on the cap of this species, it is not surprising that our sequences from this material do not match any of those in our local data base. We’ll keep you up to date as we find out more about this species.

Very best,


Thanks Patrick,

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