And I just want to say that I’m grateful for your website (old and new)and the Amanita Workshop as resources that make hunting Amanita so much more enjoyable. Thanks.

I believe I brought you dried specimens of this species last year at NEMF. It’s OB #51715. Probably labelled sect Amidella. The partial veil on these is fragile and the large specimen I found last year had only a fragment left. I thought it was a piece of the universal veil stuck to the stipe; and the sand stuck in the cap confused me. Same location, same month. This is the only member of sect. Caesarae I’ve been able to find.

In my neck of the woods sect. Vaginatae is easily the most common and diverse. Followed by sect. Validae and sect. Amanita respectively. Sect, Phalloideae would be rare if it weren’t for the common A. bisporigera. I find almost nothing from sect. Lepidella, but from what I can tell A. abrupta is probably the most common one. Found by me anyway. The couple members of sect. Amidella I’ve found were in sand dune areas.

Debbie, have any good sightings of Monotropa uniflora on your trip east?

In addition ot MO,…

In addition to MO (at least for amanitas), I suggest also watching the ?Site+news page on WAO…over the next week or so:

< http://www.amanitaceae.org/?Site+news >

We got a new northern distribution limit for A. longicuneus nom. prov., the first fresh material I’ve ever seen of something Walter Litten sent to me 25 years ago (temporarily at ?Amanita+sp-Litten_L-715), and two undescribed spp. of section Vaginatae that we didn’t have time to completely work up in the field…so we can’t say whether they are an old numbered taxon or will require (a) new number(s).

On the whole, we were flooded with the usual common taxa (A. borealisorora nom. prov., A. bisporigera (the sole member of the Phalloideae that came in), A. flavoconia, and A. amerifulva nom. prov.). We got nothing from sect. Amidella (unless one slipped under the radar and never made it to a table). There was one Lepidella (A. abrupta), and a total of 17 probable taxa altogether.

“Alien” material (brought from Massachusetts) included material (too old or too young to keep) of A. atkinsoniana (young) and (apparently) A. velatipes (old).

I think we were just starting to get a taste of the boreal forest Vaginatae when we had to close up shop and head for home.

Very best,

I went home too early!!! I’ll just bet that lots of great amanitas came into NEMF.
I wincingly look forward to seeing their portraits here. :(

Darn it.

Cool caesarea. Interesting that it is both pale (for the section) and primitive.

Nice find, Bob.

This species also came in at NEMF 2011…

Nice, Bob.

This is what Yves Lamoureux and RET have called A. murrilliana. It is unlike the brightly colored Caesareae that we know in (among other things) having the bottom of the SIDES of the stem connected to the volval sac as well ass the stem’s very bottom being so connected. According to unpublished DNA studies, it is among the more basal species of the section.

Very best,
