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

Thank you, Garrett.

Your dried material associated with this observation arrived today in good order.

Very best,

The available morphological information (sorted by genetic information that is still being worked up) is on the WAO website.

Here is the current list of possible rubescent taxa in eastern North America:

Amanita flavorubens – perhaps a species with a very complex set of different
nrITS sequences.
Amanita rubescens var. alba
Amanita sp-amerirubescens01
Amanita sp-amerirubescens02
Amanita sp-amerirubescens04
Amanita sp-amerirubescens05
Amanita sp-amerirubescens07
Amanita sp-MO02
Amanita sp-N47

Apparently missing numbers are due to the discovery that two items on the list were essentially identical in terms of the available genetic data.

Very best,

“amerirubescens” is actually a group with cryptic members? are there already known named species in this group?

I sincerely hope that you will publish this nom. prov. soon, Rod, so we have a basis for comparison for these various eastern blushing outliers.

I know, the finite nature of time, and all.

Thank you, Garrett.

I can’t tell which of the species this is by sight; however, it is a familar form of…

the “amerirubescens” group. It’s not A. flavorubens, and its probably not A. rubescens var. alba. That leaves the ones that are separated mostly by genetics at this point in time. We’re working on the problem….

I see that you kept some dried material, if you’re willing to share it, we could take a look to see where it falls in our current scheme.

Very best,

Rod Tulloss
