Amanitasp-O02” has turned out to be A. solaniolens.

the material will be scheduled for sampling for DNA sequencing.

This specimen has been received and accessioned into Rod’s herbarium.

we’re finding the genes in sp-N20 (solaniolens), sp-O02, and sp-CR18 (from Costa Rica) hardly differ at all. There’s more to be done, but there is definitely a very close cluster of slightly different anatomies associated with the anatomy of solaniolens original description. It would probably be useful to try to get shots of a dark (solaniolens) button and repeatedly photograph it as it expands to see if the dark cap turns into the more sparsely virgate cap with or without a little red staining. I guess a collection with multiple fruit-bodies in different stages of development would serve the same purpose; however, I’ve never seen a significant cluster of any of the “possibly separate” taxa in 35 years.

That last sentence is a challenge to all who read it. :)

Very best,


This looks like some of what I’ve been calling solaniolens…

especially the larger fruit bodies.

Rod, the package I mailed this morning contains two such examples.

I’m very glad the workbook is of use to you.

I’ll tell Cristina, too.

Very best,


I’ve been studying the workshop booklet you sent

and also holding my breath for the A. thiersii which came up in my yard last September so that I can save a specimen for you from Jasper county here in Missouri. Learning to take notes and be more precise with observations. My pleasure to learn Dr. T. Jon

Material received in good order, Jon.

Thank you very much.


Yes, please do include the MO observation number…

with each dried collection that you are kind enough to send to my colleagues and I in NJ.

Very best,


Got it. I am reading the workshop pdf you sent…

The code name…
By: R. E. Tulloss (ret)

is “sp-” “O” “zero” “two” The “O” is for “Ohio” from which the possible taxon was first recorded.

Very best,


Should I include the MO observation # Dr. T?

I am excited to find something new and saved this specimen.

This could be sp-O02.

Considering this possibility, I would like to include your dried material in a study of the material similar to A. solaniolens. I would like to review your dried material if possible.

Very best,

Rod Tulloss
