From Amanita of North America (fb group) this morning.

(Remember the joke about South Dakota having one sheep that is black on top?)

Sometime ago we got back a number of reads from the voucher material for mushroomobserver #279300.

At first the data were hard to interpret and I set it aside for the moment. The moment got kind of long.

We couldn’t get an nrITS sequence; but, with very careful editing by Linas Kudzma, we were able to clarify the reads for assembly of the nrLSU gene. This morning, I was quite startled to find that Amanita penetratrix occurs in North Carolina.

The voucher of this observation is our first evidence of the presence of this species south of Pennsylvania. It is still only being found in the Atlantic coastal states.

And…we have the second image of a largely white specimen of the species. It comes in the same “package” from Geoff Balme.

I was up late making our family’s seven+ generation old sugar cake dough so that the youngest grandkids can cut out cookies later today. THEN…

…an enjoyable morning for a DNA-shuffling amanitologist. :)

Very best,

The images seem pale for sp-GSM02.

unfortunately partially decayed before I got it to the dryer. HOpefully there’s still material to work with.

It was about 6" tall and quite robust with a cream/yellowish disk that darkened toward the center.
