People on MO can be very generous with knowledge, time, photographs, dried material, etc. I couldn’t manage to do as much as I do if I didn’t have many supportive colleagues…including folks on MO.

Very best,


I’ve learned so much.

Thank you again, sir. I can see this is going to be a habit. I’m going to be thanking folks a lot here!

This is another taxon with name changes since Dr. Miller’s book.

And, again, we are in the midst of changes.

Amanita virosa is a Eurasian taxon, which we do not have in North America. In the last year research has shown that we need to be aware of as many as a half-dozen white members of section Phalloideae in North America that have caps that turn yellow if you put a drop of KOH on them. A couple of them have names, the rest are in the process of being discovered by genetics studies and having taxonomists search for morphological characters that can be used to separate the taxa without the aid of DNA sequencing.

The differences that we know about so far require a microscope.

We are collecting data.

Very best,
