Observation 136480: Amanita sect. Caesareae Singer

When: 2013-06-13

Collection location: Alva, Florida, USA [Click for map]

Who: Benjamin Dion (benjamindion)

Specimen available

Same species and found within 100 yards of both http://mushroomobserver.org/136334 and http://mushroomobserver.org/136478. I would also like to note that I used one of these specimens’ bulb picture for the identification purposes of http://mushroomobserver.org/136334 (so the picture of the bulbs actually belong to the specimens in this OB).

For clarity, I would suggest you say that you dried the material “as they were in situ…unsectioned and after minimal handling.”

I meant “in situ” as “as is”… as I barely handled them and they dried perfectly in the dehydrator. I have 3 or 4 specimens that have veils and bulbs in tact perfectly…

You’ll be seeing them soon!


What do you mean by “in situ drying”?

I would understand that to mean that you left the mushroom in the ground and waited for it to dry. That can lead to decay of the fruiting body and destruction of DNA from ambient humidity…so…I think maybe I am misunderstanding you.

Very best,


Dr. Tulloss

These are the same species, just a different collection, as my last 2 observations… I will send multiple perfectly dried (in situ) specimens and spore prints to you so that many people can get a sample from you (and you’ll still be able to keep some for yourself!


The center of the cap is browner than in F11, which also has a bright yellow ring…

on the stem. This is something else. We would very much like to see this and will send samples for DNA sequencing to our colleagues.
