I would be quite interested in seeing dried material.

If you don’t have a copy of the workbook I wrote with Cristina Rodriguez-Caycedo, I can send a PDF to you by email.

MO’s email function doesn’t have an attachment capability. If you email me, I can respond with an attachment.

Very best,

Rod Tulloss

Amanita “Sp-S10” looks like a candidate, as does Amanita "Sp-F11."

If I can procure some material – and I’m pretty confident I can – would you like some?

My best,

Hello, Logan.

In the last couple of years a long study of the species of Amanita sect. Caesareae culminated in a paper reporting genetic data for many taxa in addition to those with formal names. It is possible that your material represents one of the new taxa. Many of these have code “numbers” on the WAO (www.amanitaceae.org) website.

The list of species known to me is listed on the Caesareae “directory page”:


You can go to the list at the bottom of the page of the names beginning “sp-”. You will want to filter out the species not known from the SE U.S. “AUS” stands for Australia. “M” stands for Mexico (but “MO” is for Missouri). “CR” is Costa Rica. “Thai” is self-explaining. The species code including the name “Laferriere” is from Mexico. The other taxa are largely from the SE U.S. I think you will find at least one taxon that has a red cap center and yellow cap margin rather early in expansion of the cap (as compared to jacksonii that is all red at first).

Very best,

Rod Tulloss

Thank you, Judi …

The stars must have aligned. I’m normally awful with a camera, let alone one attached to my phone.

I’m deep enough in at this point that investing in a legitimate camera seems inevitable. Your encouragement, however, might allow me to hold off until the fall :)
