The white-capped species of sect. Vaginatae are very interesting and diverse.

At the 2014 Northeast Mycological Federation’s Sam Ristich Foray (just ended), a single specimen was collected of a species of the Vaginatae with a white cap. The stipe, gills, and interior surface of the volval sac were various shades of pale orangish white. The volval sac was proportionately robust (with the sac walls over 2 mm thick at mid-height. A fascinating collection.

When we have obtained DNA from white-capped Vaginatae from eastern North America, we have found a very large number of quite distinct sequences of DNA for the genes being examined. There is a very big puzzle here.

Very best,

Rod Tulloss

Thank you for your offer.

It is very much appreciated.

We are currently working on many species groups. Rubescent taxa do form a very interesting group about which we want to know more. The species of sect. Vaginatae in boreal and near boreal forests are very diverse. Indeed the diversity is so extensive that there has not really been a concentrated effort to deal with the section to any breadth or depth.

Very best,

I don’t mind grabbing samples of what I find out in NS. There has been a lot of elongata and rubescent pale ones. I’ll remember to save you some stuff. I have no dry amanita collections presently

Did you happen to dry and retain this material?
