thanks very much for the knowledge tulloss! though the cap was mostly a beige color while fresh, not red. if anything, a muted white.

The cap of your mushroom looks red between the warts?

Is that the way you saw it fresh?

“(Fr.) Bertill.” is an author citation

It means that Fries created the original binomial (scientific) name. It happens to have been “Agaricus gemmatus.” Then a certain fellow named Bertillion wrote an article for a French encyclopedia of medicine in which he “recombined” the name in the genus Amanita.

You are quite right that this gives a very specific meaning to Amanita gemmata. It links it with an illustration in an old book, which is the name’s definition at the present time.

If you want to say something different, MO has some flexibility and you can say things like:

“Amanita gemmata sensu PNW authors” (meaning “Amanita gemmata in the sense of PNW authors”)

Or you can say

Amanita gemmata group

which is fairly vague since there are several species around the world to which the name has been applied by one author or another.

From what we know at present, the true gemmata doesn’t exist in the Western Hemisphere. Even in the PNW alone, there is genetic evidence for more than one species in the “gemmata group.”

So you have every reason to want to avoid too much precision.

Very best,

Rod Tulloss

every time i select a scientific name the database selects something more specific that i am unfamiliar with…is this normal? i don’t know what (Fr.) Bertill. means.
