The nrITS for this collection has been withdrawn from GenBank.

It was of minimal length and included only parts of 5.8S and ITS2 subsequences of the nrITS.

Very best,

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

Very interesting.

Onward!

as I was packaging the dried specimens of this and the 279639 — your observation that they were probably the same was made that much more evident in their dried condition. They are indistinguishable save for size.

The caps are a match.

And they all have species-specific co-evolved gut fungi!

Maybe gut fungi are the most diverse organism in the world! Yay, for gut fungi.

But what kinds of beetles? Estimates on the numbers of insect species range from anywhere from 3-30 million! Science has described 1.5 or so million species of all things to date . . . 500K of them are beetles. 1 in 3 things known to science is a beetle!

That combination seems to be the way to go.

I had a children’s book when I was very young in which the mother turkey says nothing to the little turkeys except, “Eat beetles, eat beetles, eat beetles.”

Now the equivalent voice says, “Get data, get data, get data.”

Very best,

It was NOT FAR FROM obs 279639

Same hillside of beech/oak/tulip poplar and perhaps a dozen yards distant. The big difference here is size. This specimen is much more robust.

I don’t know, I’m hoping all these pics and specimens help! But without a good handle on variation we kinda gotta take everything as different until otherwise proven. I’m assuming our evidence for shoe-horning them together will be good molecular comparison (phylogenetic analyses) concatenated with our morphological observations.

The coloring (indoor shots) are reminiscent of MO 279639.

I still feel uncomfortable with the tremendous variety of Vaginatae with the differences in umbo, depth of stipe insertion in substrate, colors, and pigment patterning on the cap. I knew there were a lot of these critters out there, but I don’t think I really appreciated the diversity and all the subtle cues that may (or may not) work to segregate the apparent species.

Very best,

Rod
