The way things are going it looks like we will eventually merge the two pages cited above into a single page under the new name Amanita americitrina.

Very best,

It’s very nice to see that the citrina=like taxa are showing in Michigan.

As you may know, there is a project going on this year to collect samples of citrina-like taxa in North America.

Since Michigan was the state in which one of the citrina-like taxa was originally collected, I am very interested in collections from Michigan in the remainder of the mushrooming season of 2013.

The citrina-like mushroom originally collected in Michigan was placed in the wrong species when it was named: Amanita brunnescens var. starminea.

What we know about this mushroom is that it is a good species on its own; it looks like field guide illustrations labeled Amanita citrina; and it probably ranges at least from southern Canada to Florida. In the present project, we don’t have any material from Michigan that is recent enough to easily yield DNA. I hope you and other Michigan mushroomers can help us with our project.

We would like to obtain dried material that is backed up by good photos on mushroomobserver of material that is a citrina-look-alike from several different sites (different counties if possible) in Michigan.

If you would like to help, we need material documented on MO to be thoroughly dried and mailed (at regular postal rates, nothing fancy, in a sturdy container) to

Herbarium Amanitarum Rooseveltensis
P. O. Box 57
Roosevelt, NJ 08555-0057

If you can help us, I thank you in advance.

Very best,

Rod Tulloss
