It seems you’ve collected this species several times.

We have found more matching nrLSU sequences. Linas pointed out to me an “N” that should really have been called out as an “A”. A small number of errors in converting the raw data to sequences for GenBank can really contribute to uncertainties that can be set aside. So it’s good to have another mind and another pair of eyes. Really good. Thanks to Linas (in more ways than one) we’re going to have four examples of “sp-N66.”

Very best,

Rod

With a good chunk of time from Dr. Kudzma,…

I am back to “sp-N66.”

I never planned to be in systematics,..

…with a background in chemistry, math, logic, philosphy, poetry, and (later in Bell Labs) electronic engineering and international standards development.

I guess logic and methodology were always part of the story. All of the things I have studied or learned by immersion are (to my mind) branches of aesthetics…a very strictly constrained form of aesthetics perhaps.

This is all fascinating stuff.

I’m indebted to you for all the tireless teaching! It’s exciting to be doing this with an eye toward learning more and actually being able to contribute something useful for furthering the knowledge base.

I’ve said it before but I’ve been looking at and enjoying studying mushrooms since the late 80s, and one of my early guides (which rides in my Jeep with me) already has your name in it (Phillips) so it’s great to be able to make this connection.

Also as you know I have a PhD in systematics and never managed to get an appropriate employ. So it’s nice to keep doing science in my free time!

After several days of further study, I think it is more likely that this is something new…

…and not “sp-N66”. As mentioned on other observations today (280358 and 176966 are examples), further work has led me to this conclusion. Amanitasp-N66” has been limited to the original Connecticut collection; and separate new temporary codes have been assigned for each of the vouchers of observations over which I have stewing for several days. The new temporary codes are “sp-N68”, “sp-S12”, and “sp-S13”. The first puzzle is due to Garrett Taylor; and the last two, to Geoff Balme. I am grateful to both of them for their collecting and for the efforts they make to communicate their finds to me. Thanks to you both.

Very best,

Rod

N66 just doesn’t roll off the tongue.

N69 . . . now that has a nice sound to it.

Leafhopper lady who made a mess of the group I was supposed to “straighten out” for my Phd (good luck there) named a huge swath of them with random combinations of letters, rather than using latin/greek combining forms. Fun!

Data will be collected on the techtab of the following page:

It appears that this species has been collected before in Connecticut and New York. It took a little while to work this out because (going over the details of original date) there are two character positions in the nrLSU sequence that seem to be variable within the species as noted earlier.

OK, it looks like this might be in a very closely related group (even a single species)…

with “sp-N66”—-based on the nrLSU sequence.

I’m working on that.

There are three character positions with differences (from a total of 1494 character positions). One is an extra “T” in a “single-T repeat.” That can be discounted; so I’m exploring original data with regard to the other two character positions.

Very best,

Rod

We have DNA. A bit of a puzzle.

We have received the dried specimen. Thank you. It is being accessioned in Herbarium Rooseveltensis Amanitarum (RET).

There are some interesting ones popping up

I’ll get out again Sunday morning. We’ve had some good rains and heat.
Should be some fun stuff coming up.
I’ll look at A. keesii

Quite impressive.

Last night I was interacting with Stephen Russell concerning two collections of his that were somewhat similar in appearance and turned out to be very close to, or the same as, Amanita keesii. This mushroom has some of the same feel, but perhaps the umbo is more pronounced. This will be an interesting mushroom to review.

Very best,

Rod
