Observation 151112: Amanita sect. Amanita
When: 2013-11-03
0 Sequences

These were collected by the Burghardts in the Speedwell section of FPP (a more exact location with ~GPS coordinates is a possibility).

> The beige caps look shiny and glutinous, and are indeed feel a bit sticky when touched.
> The volval material on the disc is grayish.
> The striations are 2-7 mm long.
> The short gills are very plentiful, variable length and squarely cut off.
> The stipes are hollow (not shown).
> The stipes have a yellow tinge to them — not sure if they were like prior to collection or changed color afterwards.
> None of the fruiting bodies had a saccate volva — it’s possible it was very friable and got lost during the extraction.
> There is a noticeable smell of raw potatoes emanating from these mushrooms.

Dimensions of the largest fruitbody:
The cap is oval-shaped, 7.8 × 6.8 cm; the specimen is 10.5 cm tall; the stipe is oval in cross-section, 1.7 × 1.2 cm.

The material is saved for RET.

working independently or cooperatively on amanitas is EVERYONE’S business! at least, everyone with both an interest and a talent.


Rod has decided I am his “enemy,” but that is not true. I also love amanitas, am fascinated by amanitas, and have been collecting, documenting, talking about, writing about, drawing and photographing amanitas for almost three decades.
I am not in competition with Rod, but in conjunction with Rod, whether he now cares to acknowledge what I have been doing all along or not. As I have said elsewhere, there are dark human forces at work to break our former friendly collaboration. I bear Rod no animosity, but nor will I hold my tongue when I see problems or have questions. NO ONE is infallible.

Jay Justice set up a conflict between Rod and I way back at the NAMA in the SE, when he asked Rod to basically do the exact some talk that I had already agreed to do, thru the toxicology committee. Jay has been a dark force for a while now. It was the company he kept. But we are who we are, no one can change our basic natures. Like attracts like.

I have tiptoed around Rod’s feelings for many years. At a NEMF event several years back, where Erin and Noah and I were all there, Gary Lincoff asked ME to do the amanita table talk. I refused, because Tulloss was there, and I didn’t want to step on his toes. Also, the NE is not my bailiwick, and I knew that Rod would do a far better job than I would, knowing the amanitas in his own backyard. But when we head west, it’s my turf. And I do know those western amanitas, and I get better at it all the time.

So, continue to do the good work that you already do, Igor, and don’t worry about handicapping your own self for the benefit of someone else. Because truly, they would not do it for you. No matter how flowery the language.

I believe these are in Rod’s hands even though Naomi’s acknowledgment is lacking. I suppose I could check my records and those of the NJMA herbarium at Rutgers to trace the actual fate of this collection.
Over the years John & Nina B. and I have been diligent about sending lots of interesting material from the Pine Barrens to Rod. We still do when the opportunity presents itself. Unfortunately, there’s been little feedback on our collections, apart from the customary and courteous accession confirmation comment on MO, which I understand is both a reflection of Rod’s research priorities and the general understanding – as you point out – that even a very experienced researcher can be overwhelmed with both the material and data of all sorts. Too much to do and too little time to get things done to one’s satisfaction…
I didn’t do microscopy on these for two reasons – I didn’t get a reticle for my scope till Dec. 2013 and Melzer’s only became available to me the following year. I have improved since then on getting “the basic stuff” done – some of my obsies have spore size data and pix. I also keep small samples of some interesting amanita collections in case I decide to sequence them on my own (I do expect to run out mysterious boletes at some point in the future). :-) If this ever happens, I hope Rod wouldn’t perceive it as a competitive move on my part, as I have absolutely no intention of encroaching on his turf.
Some taxa in sect. Amanita have pulverulent/crumbly/friable volva, e.g., subsection Amanitella.

maybe it was the RAW Potatoes …

which is characteristic of the Mappae in section Validae?

Did you actually send this to Rod back in 2013? Ever hear back? anything done once it arrived? This is a very curious critter.

Did you ever scope these, or use Melzers? It doesn’t really have a bulb, either.

Yeah, Validae shouldn’t have striations and should have a PV. But you know, there are always those weird exceptions to the rule. A friable UV is of course a character of the Validae, too.

This is why I really think that we should be doing some of this basic stuff as collectors, rather than sending everything to a single rather overwhelmed location. Do you still have any of this collection, Igor?

How could this be sect. Validae if one considers the presence of marginal striations and lack of PV?

Looking forward to these, Igor.

I’m wondering if…

these may be examples A. crenulata, or something else from section Amanita. Sticky caps, narrowly adnate gills, short-striate caps, and color of caps and UV deposits support this idea. Also, the ring on crenulata is fleeting. In the bottom photo it looks like the large mushroom may have a bit of material clinging to the stipe. Lack of basal bulb supports the Vaginatae proposal.
