is not preserved. She says she will have an eye out for these beautiful red caps when she is surveying in the preserve.


these look similar to some of the Mexican/South American flavoconia sp…

Assuming that these are on their way to you, it will be interesting to see what your future DNA analysis shows.

Thank you for contacting me off-line, Sibylla.

I hope to see you preserve some day. An oak savanna would be fascinating for someone interested in the Amanitaceae. In the past have you noticed that you have both nonmycorrhizal amanitas in grassy areas as well as mycorrhizal amanitas with the oaks? Do you have Cottonwood or Aspen in the preserve as well as oak?

I drove across the plains states four or five years ago during a period of summer rains. I saw a number of undescribed specis of sect. Vaginatae associated with oak and A. populiphila associated with Cottonwood. There were not a large number of mushrooms seen on the trip, but the ones that I saw were not the familiar species of the eastern forests and the Atlantic Coastal Plain.

Very best,

Hello, Sibylla.

This picture is very interesting to me. We occasionally see a specimen of flavoconia with a red cap; however, I have never seen this intense a red. I am quite curious about this material. I have generated an alphanumeric “code name” (Amanita sp-MD01) for red material sent to me from Maryland, but I have no photographic image of that collection.

In eastern Asia, there is a species with a number of similarities to flavoconia (called A. flavipes). I understand from correspondence that genetic studies seem to able to separate this “species” into a number of species and that newly discovered “hidden” species can be told apart by the naked eye and microscopy once they were discovered from DNA.

There are multiple entities of the flavoconia “group” that have been distinguished since back in the days of Charles H. Peck; however, there may be still more to be found. Your images suggest that you have something that might be different from flavoconia in the strict sense.

I would like to add my request for part of this material to my request of a few moments ago for part of your material of A. amerirubescens (a provisional name).

Very best,
