You’re right, Ron (per email).

I should assign a temporary code number to this species. It will be Amanitasp-T47.”

Very best,

Rod

You’re welcome, Ron.

Maybe I’ll get lucky and find another one or two this year.

There was only one relatively close match for the nrITS.

The closest sequence was one of the sequences that are close to __A. __"__pseudocrocea__".

Very best,

It does look fairly unique.

We were able to obtain most of the sequence for the “proposed fungal barcode”…

from your collection of this material. As you might expect, the sequence was unique. I will report further when it’s not so late at night.

very best,

Rod

We have accessioned this material and scheduled it for DNA sequencing.

The dried material has arrived in Roosevelt. Thank you very much.

Very best,

Rod

Thanks, Ron.

Yup. I have the same reservations and the same possible positives. Well, we can see what we can do with a comparison when the time comes for that to happen.

Very best,

Rod, Amanita sp-T05 could be

a possibility. The dried fb does have darker shades of brown on the cap versus the fresh specimen.
My spore measurements are always approximations especially with Amanitas with roundish, nonamyloid spores. I seldom go the 20 measurement route, 16 in this case, so I have to put in the qualifier.
However, I see that the Q values are close and the actual numbers are pretty much in range, but on the low side.

The proportionately short volval sack…

is consistent with what little we know about sp-T01.

R

What do you think abou this?
By: R. E. Tulloss (ret)
2014-07-01 16:40:28 CEST (+0200)

Could this be a fresh collection of sp-T05? The spores could be small for that species. But a see a tilde in front of the spore size range. I assume that that means the range is an approximation in some sense?

If this isn’t sp-T05, I don’t think that we have this creature in the Texas checklist.

The job manages to stay challenging…

Very best,

Rod

Thank you, Ron.

Not sure if I know this one….so I’d like to examine part of the collection if possible. EDITED

No surprise in that…anymore.

The colors of the cap slightly suggest something in the crocea group; however, I understand that group as much by the layering of the wall of the volva sac and the shortish marginal striations on the cap as by cap color. Consequently a comment about cap color may or may not hold up in terms of determinations.

Right now I collect data like crazy on the theory that when I have a big pile of it, then maybe there will be a “pony in here somewhere.” :)

I just got four mailing packets from you today; so here’s a big “THANK YOU” for them.

Very best,

Rod
