I have just gone through the data for the three citrinoid species that were discovered in my project with Dr. Hughes. We don’t have a collection of any of the taxa from Maine or the Canadian Provinces. It would be very good to have such material, Terri.

I will send you a range spreadsheet. Any state not included is a state from which we have no material.

Very best,

Rod

I’m terribly sorry but I just noticed that I neglected to send this sample to you as you requested. Do you still want it?

Terri

Good photo documentation, Terri and Donna.

I’d like to see this material also, Terri and Donna. It would probably save time, effort, and money to send me your citrinoid material in a bunch. At this point (Dr. Hughes has a massive teaching load this Fall), it will not slow down our process if you wait until you have your 2013 collections of citrina-like species all gathered together.

To all readers:

This is the first time that we’ve tried to show (on WAO) the process of trying to separate collections of look-a-likes. I’ve been trying to use the multiple pages that have resulted as teaching examples in postings on MO and elsewhere. If your not familiar with what’s been going on, I’m referring to the fact that we now have five pages in various states of development that were intended to describe our developing knowledge of three citrina-like taxa from eastern Norther America that were identified in genetic studies. We are pretty much convinced that two of these species already been formally described (although their names may have to be changed), and one is a “wild and crazy gal” (Amanita is feminine, remember)…an infraspecific “hybrid swarm.” Very cool stuff in my humble opinion.

The five pages are:

(1) http://www.amanitaceae.org?Amanita+sp-lavendula01

(2) http://www.amanitaceae.org?Amanita+sp-lavendula02 and
http://www.amanitaceae.org?Amanita+citrina+f.+lavendula

(3) http://www.amanitaceae.org?Amanita+sp-lavendula03 and
http://www.amanitaceae.org?Amanita+brunnescens+var.+straminea/...

I’d like to ask those who read this post to let me know if this presentation of developing knowledge on multiple pages has been interesting or confusing or some other more appropriate (to you) adjective. We think that we will be wrapping up this mode of operation for North American citrinoid material in about another year or so. Would you like to see a “Project Central” feature on the cite that keeps track of projects for which we need the assistance of citizen scientist collectors, photographers, observers, note takers, etc.?

Do you have friends west of Missouri and east of the Rockies that collect mushrooms and are not posting on MO? How do we reach these folks with announcements of “Amanita most wanted lists”? What are your ideas?

Should we take another group that is identifiable genetically as a set of distinct species and follow through the process of working that group out on WAO pages in a similar way?

Would you like to see the eastern North American rubescent Amanita taxa treated this way? How about the white destroying angels?

Please post responses here or email us via the MO email feature. Thanks in advance for your comments.

Very best,

Rod
