OK -Thanks!

However, your notes (and my herbarium label) say this material had 4-spored basidia.

So this particular collection is probably not bisporirgera.

I haven’t had time to work on the sequences of Phalloideae in recent months. We are still getting some sequences back from material sampled in the past.

At the moment I’m focusing on section Vaginatae in terms of sequences…for the most part.

Very best,

Rod

If it is from eastern North America and has 2-spored basidia, we only know of

one taxon — bisporigera.

Rod, because it has 2-spored basidia…

…would we modify the name to A. bisporigera (instead of A. bisporigera group)?
Does having 2-spore basidia rule out the other possibilities in the “group”?
Also, do you have sequencing results for this collection, and if so, how did the results match up with others in the database?

This material has two-spored basidia.

The proposed determination is correct.

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