The key thing is to know that you didn’t have yellow on the bottom of the partial veil.

I don’t have any immediate need for more data. I hope you got the workshop PDF.

Very best,

I did peel away the partial veil from the stem in the field, there was no yellowing. It was the same on the underside as seen in the photos. I do have more photos of the base, both before and after it was excavated. If you are interested I can post those here later tonight.

Did you happen to notice the color of the bottom of the skirt on the stem in your material?

At least one of the North American rubescent taxa is distinghuished by yellow volva material pretty much covering the bottom of the partial veil.

Very best,

Thank you very much for the links and information! I do understand it’s a European taxon and have changed the proposed name to reflect this.

If you’d like to know more about the eastern North American rubescent taxa,…

here are some pages that might help out;

http://www.amanitaceae.org?Amanita+flavorubens

http://www.amanitaceae.org?Amanita+rubescens+var.+alba [This is not a variety of the European rubescens; it’s a unique North American taxon.]

http://www.amanitaceae.org?Amanita+sp-amerirubescens01

http://www.amanitaceae.org?Amanita+sp-amerirubescens02

http://www.amanitaceae.org?Amanita+sp-amerirubescens04

The last three are taxa that have been separated by gene differences.

A page that combines the last three taxa into an (erroneous) single description is here:

http://www.amanitaceae.org?Amanita+amerirubescens

Why do we still have a mishmash page like this? Because we don’t have good written descriptions of the fresh material of the three code-numbered species. The Amanita Bear (a cousin of Smokey) says, “Only you can describe the material you photograph and dry.”

Very best,

This is probably not A. rubbescens, which is a European taxon.

This is more likely to be one of the several eastern U.S. rubescent taxa that are now being discovered with the significant help of the genetic tools developed in the last several decades.

I’m part of a group that is looking at the eastern U.S. rubescent taxa. If you are interested in participating, we would be very intereted in dried material that is accompanied by a desription of the fresh material and good images here on MO.

If you’d like to participate, I can send you a workbook that Cristina Rodriguez Caycedo and I have used in workshops/seminars on Amanita. It includes information about note taking, drying, photography in natural light without glare and with good depth of field, etc.

If you email me via MO, I will then have your email address and can send the workbook.

Very best,

Rod Tulloss
