The easiest S.African species to find by searching for “pink gills” in Lepidella….

on the WAO website is A. roseolescens. However this is not illustrated as having a radicating stem base.

Is it possible to dry this specimen and send me a piece (say, a half of the mushroom split down the middle) for microscopy and DNA sequencing?

This species appears to belong (as noted) in a group on which I have worked a good deal. The group was originally defined by C. Bas (1969) and was studied with regard to genetics and biochemistry recently by B. E. Wolfe, Tulloss, and Pringle (2012). The full citations for these publications are given here:

Very best,

I didn’t see the radicating stem base when I first arrived at this page…

can be a marker for Amanita subsect. Vittadiniae. This means that this species may not be mycorrhizal (may live on dead vegetative matter). The pink gills might be a clue.

Let me see what I can find on this.

Very best,

Rod
