Meltzer’s negative

My Meltzer’s is ~20 years old, if makes any difference.

I am uncertain of the apparent patch because…

it is delineated by cracks that, in places, clearly descend into the pileus flesh. Also it has rings of wart remnants in broken concentric circles on it. Hence, it might be the cap’s skin rather than a patch. Debbie’s suggestion certainly made me take a long look at it.

The clearest limb (on the far right of the top picture) seems to be a big recurved scale that split away from the lower stipe and the upper part of the bulb. To me that actually is convincing evidence that there wasn’t a membranous volval limb present.

Nevertheless, it is better to examine the material microscopically.

Since most of the volva is lost from the cap and the cap seems to have slightly dried in situ, I wouldn’t expect that the appendiculate material would have necessarily survived.

Good questions, Debbie.

I am not entirely convinced that this is a lepidella…

I don’t see an appendiculate margin. Unclear what type of volva is present at the base, but there does appear to be some sort of cup, along with a sl. pointed bulbous base. If you carefully examine the cap of one fruit body, you see a patch of UV remnant.

Your description and photo of Amanita sp AZ13 does not list Pondersosa pine as a symbiont.

Got Meltzer’s Bob? A spore check would at least help get this interesting critter to section.

gotta love…

monsoon season in the SW!

You have no idea how much I wish I was there!

Keep on finding and posting those marvelous and unique SW amanitas, Bob. Great work, as usual.

All yours

Rod — Any Amanitas I find I will gladly send your way.

Similarities to sp-AZ13 include…

The robust fruiting body (with a stem like something out of Stonehenge) and the radicating base of the bulb.

I think this is very close to Amanitasp-AZ13.”

The species is very reminiscent of A. polypyramis, but (at least at present) seems to me to be a distinct taxon.

Bob, do you have a photo showing the area of the stem where it meets…

the top of the bulb?

I would also like to impose on you for part of this material.

Very best,

Rod
