MO 169768 is accessioned as RET 643-4. The sample has been submitted for sequencing. If DNA could be extracted from 643-4, then the reads from that DNA will come into Roosevelt about 100 samples from now.

Very best,

Rod

Hi Rod. Nice work!

I just went through my MO Vaginatae observations, and I think this one, obs 169768, may represent the same species (as 74501). 169768 was found in the same area (south-facing oak-dominated ridge) as 74501.

If you can find more and have the time to measure them with the paper…

rulers, I’d very much like to know the dimensions of the specimens you find.

If you don’t have a set of paper rulers (that follow the curve of the cap, for example), let me know. I’ll send a PDF that you can print out.

Thanks very much for your continuing support.

Very best,

Rod

I checked my photo records…

and this was found in Ricketts Glen State Park. I edited the observation as per this detail.

Actually, I remember the area where these were found… accurate to maybe 10 acres or so. It’s a spot I visit often. Oak dominated mixed woods, some hickory possibly mixed in and maybe a stray hemlock here and there. South-facing ridge with some level shelves. The past few years I’ve been looking there for more of these with no luck.

These were fairly large for grisettes, as I recall.

Increase observable spore dimensions by ~17%. (This appears to translate as follows: 7<L<11.2, 6<W<11, 1<Q<1.2.)

We got some DNA data today including some raw data from this collection.

This species is another one in the provisional series Penetratrices. It differs only slightly from one collection in the TENN herbarium for which Dr. Hughes has a “proposed barcode gene” (nrITS) sequence. The difference involves a four character indel. Since we only have two samples to compare, we really can’t make an additional statement, although I will write to Dr. Hughes about her findings that I way not have seen.

You pictures are especially valuable.

I had a note that this observation might fall under Amanita sp-GSM07; however, we can now be sure that this is not the case.

At the moment, we don’t have a page for the present species on WAO.

Very best,

Rod

Thanks Dave,
