I don’t see a bulb here.

You mentioned the discovery of a bulb on one of your collections with a more yellow cap. I had the same experience myself when I discovered a bulb on the bottom of the first collection I made of sp-S01.

Very best,

thought MO 243416 was vaginatae, but our friends noticed a bulb!

Do you see similarity to MO 3243416#

We have received the dried specimen and it is being accessioned for Rod’s herbarium. Thank you very much.

Thank you for all your teaching sir!

Yes. That’s one of the possibilities.

But that is the name of a specific European taxon. It was not a correct name in North America. It’s like the mis-use of rubescens.

Also, some people dropped the “vaginata var.” or “vaginata f.” and just used alba; however, that’s not a valid name. The first use of Amanita alba was as a name for the European species, A. ovoidea.

Very best,


I just pulled out my Collins Field Guide

and found that they call A. vaginata “a variable sp with numerous varieties and forms. F alba (deSeynes) Vesely: entirely white!” They in fact illustrate a white one! (beautiful illustrations by the way).

So that was what it would probably be here before we realized our species were significantly different from the Euro ones.

In North America there was correct applicable name.

People applied European names or didn’t use a Latin name — “white thing like vaginata”.

Very best,

these White, delicate, ringless Amanita sp. before these modern Phylogenetics techniques started splitting things up?

Thanks for collecting this. DNA is showing that there are multiple white or…

whitish species of section Vaginatae. Some have a distinct enough coloration or have the volva graying so they can be separable at sight, but I am a long way from being finished working my way through the data.

Very best,
