The decoration is just under the edge of the partial veil.

If you would like to know what DNA was extracted from this specimen (or any MO-originating specimen on the website) search for the MO number with the sitewide search function using a string composed like this:


This format is very specific to the HTML code used to link to an MO observation.

If the MO observation is included on the site, you will be provided with a link to that page. Find the MO number (in our example 143582) on the targeted page. Following the MO number will be my herbarium accession no. In this case RET 565-3. Go to the top of the page and search for the numerical part of the accession number string or go to the datafield marked “GenBank nos.”, select the column labeled “voucher”, and put the 565-3 into the box under the word “search:”. In this way you can find both what sequences were derived from the material representing an MO number and the species to which the collection was assigned using all methods available.

There are two somewhat similar Caesareae in the SW. The second is Amanita basii.

The two are related rather closely (according to the nrDNA sequences); however, they are more distant from each other than are the Mexican microspecies when they are compared in an alignment using four protein coding sequences.

Very best,


so, what did these end up being after DNA analysis?

I notice that these stipes are NOT strongly ornamented, although other purported cochiseana material is.

does that make the stipe ornamentation a variable rather than a given, or is there more than one SW caesar?

Thanks Bob,

This material has been recieved and accessioned into Rod’s herbarium. We have scheduled it for DNA sequencing.

You fix ’em like the Italians do with their caesars.

someday, I will try these for myself!

Yes, they are good

Debbie — Kind of a cucumber, slightly briney taste raw, and they are best that way in salads with a light vinaigrette. Cooked they taste rather ‘eggy’ to me. Meh.

have you eaten this species, Bob?

Just curious about the taste. Its beauty is beyond dispute.

Not a great monsoon

Just a lot of driving. July was great, but the essential August rains have been disappointing. I’m still hopeful we may see some more fruiting as we’ve had a bit of rain in the past few days.

Again, Bob, I’d like to put in a bid for part of this material.

There must be a good monsoon this month in the southwest.
