Darn rhumatism.

The link works now.

Very best,

The link below doesn’t work because “punctata” is misspelled.

I would appreciate it, Lucy, if you would look at my description which is based…

entirely on your photographs. The description is posted here:

on the technical tab.

I have pretty much followed Dr. Wood’s language in reporting his description (indicated by use of quotation marks).

Very best,


I have completely rewritten the last comment here.

After re-examination of the images and examination of the dried material, my previous impression about the volva is revealed to be incorrect. The volva is saccate and white on the lower exterior surface and pale gray on that part of the interior surface that is visible. The upper part of the volva limb becomes gray and crumples downward. I previously took this to be a ring on the stem; however, that is a misinterpretation. The stem is pallid at the top and bottom. The middle third is distinctly grayer and is punctate. These dots (forming the punctation) are also gray and are distinct when the photograph of the larger fruiting body (side view, base in ground) is examined at sufficiently high magnification.

In Wood’s 1997 monograph there is one species described with a pallid gray to mouse-gray to gray-brown cap and a stem with gray tint and gray punctation.
Unfortunately, the description is very brief. However, the spores and basidia described by Wood seem very like those that I found in your dried material.

Wood placed his material in A. puncata (now called A. cheelii). I studied five collections of the original material of cheelii, and the results are reported here:

The spores reported in my type study are of the size reported by Cleland and Cheel in their original description of A. punctata (A. cheelii). While there are apparently some macroscopic similarities between cheelii and the species called punctata by Wood, the spore size in the two species differs markedly. The spore size found in your material, Lucy, is that of Wood’s material.

Hence, I think that the most conservative move for the moment is to say that this material could be called Amanita punctata sensu A. E. Wood…as a tentative ID.

Very best,

We received very good quality DNA sequences (nrITS and nrLSU) for this species. They do not conflict with placement of the species in section Vaginatae. I hope to be able so say something more soon.

Very best,
