Notes: It’s not the first time that I notice that these mushrooms doesn’t bruise red, on cap, gills or stem. They have already pink tones on ring, stem and eventually on cap (not in these particular ones). There’s something in these cap colors that makes me doubt of the ID.

Thank you for keeping me in loop.
This collection has been sequenced by Dr. Karen S. Hughes. We have obtained nrITS (“barcode gene”) and a nrLSU sequence from the material. These sequences support the identification of this specimen as the same european A. rubescens group as your previous observation http://mushroomobserver.org/136333

The packaging was super.
Thank you for your support of our research.
I have been told that recent sequencing suggests we may have more than one species passing under the name of novinupta. This was a surprise. To tell you the truth, perhaps one of them was brought to the U.S. from Europe and the others are native here. I simply don’t know. Coker’s rubescens var. alba is quite distinct from the European material I have seen in Norway and in illustrations. It is much more like the typical eastern North American rubescent entity, which is frequently posted on MO.
Also let me make a correction. I have relied a great deal on the eyes, hands, and minds of many European authors (especially the late Dr. Bas who was my mentor). Perhaps I have learned a little; I need to spend much more time collecting in southern Europe. I think my “job” when I am interacting on MO is more to participate in sharing knowledge and to help people think things out for themselves rather than to be an expert in all species.
:MO provides an opportunity for a two-way exchange of information.
Thank you, Elsa for your positive response. There is a little pamphlet that I can send you in the form of a PDF, which may prove of some use to you.
I can’t attach it to email sent through MO. If would be so kind as to email me via MO, I can respond directly to you with the PDF.
But I quite often find A. rubescens with very little to almost no clear reddening especially when it is hot and dry.
That was the reason why there has been described a taxon Amanita pseudorubescens which proved synonymous though.
As long as there is but a faint reddish or pinkish stain somewhere in the fruitbody I would still go for rubescens.
Cap resembles Amanita franchetii but this taxon clearly is all in all purely white-fleshed and has a bit different gestalt.
I have these two. If I’ll be succeded in drying, I’ll send them to you. I saw the red bruising only when I cutted the stem in half to dry, and only a bit in the most swollen part of the stem.
I read your comments on obs. http://mushroomobserver.org/50842 and I think I saw something like A. novinupta here. It was in 2009, at that time I didn’t know it was an american sp, so I classified the photo with that name. I’ll upload the photos in a new obs. , but I don’t see that cap color frequently.
If you dry one of the questionable collections, I would be very interested to see it. I am part of a group that is comparing species called “Amanita rubescens” on the two sides of the Atlantic Ocean. The group is using both morphological and phylogenetic methods.
