Very best,


The genetic data from your material is likely to be used in a forthcoming

paper on the Caesareae and their evolution taking account of glacial refugia and the passage of taxa in and out of such refugia. The first author will be Santiago Sanchez-Ramirez, their are many other authors on the paper (including me and many active Mexican mycologists).

Very best,


Thanks RET!

I noticed the location info wasn’t updated yet, but I’m looking forward to sharing this with my professors at FGCU!

Glad I contributed. Cheers.

We received word on sequence data from your material.

Amanitasp-F11” is still only known from Florida. Your data is starting to be included here:


Thanks again for you material, your photographs, and your data.

Very best,


Absolutely. Plentiful information.

Thank you for all the information. You really “went the second mile.” I appreciate the effort that I know it took for you to gather all that together.

Very best,

The “identifying numbers on the packet” are actually the DSC numbers from my camera and computer… so “665” was actually “DSC_665” on my Nikon, which became “DSC_1732” once uploaded onto my computer.

I utilize this numbering system when drying/spore printing scores of specimens at the same time (mostly with multiple dehydrators)… keeps it easy and very organized, especially since I’m out of the door for work or school as soon as I turn the dehydrators on… and then I move dried specimens into the desiccant chamber and seal spore prints in my still air box as soon as I get home from work or school. Then I label, put in order by number in my fridge, and get to bed! It’s very efficient considering the little time that I have to spend on this hobby.

Use this OB number (136334), as well as the other “Amanita sect. Caesareae” OB numbers, for the official numbering of each bag you get from me. Every bag I’ve sent you (or will send you) are vacuum-sealed and have their individual MO OB #s on them. This is probably the best way to keep them organized.

As far as my collection location goes, I’ll give you some background information first:

All of my OBs from “Alva, FL” were found underneath old growth Live Oak (Quercus virginiana) hammocks, and by “old growth”, I mean that these areas are the largest areas containing this many old live oak trees in Southwest Florida. This particular area has been private property and in the same family for at least 100 years, and they did not log much of the oak and NONE of the slash pine.

Historically speaking, Alva (and very few other parts of SWFL) used to be connected to Northern Florida via “corridors” of higher elevated areas, such as oak/hardwood hammocks. These pockets or strips of land are the most “stable” ecosystems which would also explain why my only Chanterelle, Pisolithus arhizus, Armillaria tabescens, etc. finds have been from these areas.

Another favorite hunting spot of mine is about 30 miles south of this location, and it features 200+ year old Live Oak trees…

In between these two locations are cypress domes, desert scrub, and “evergladesish swampy areas”, which contain slash pine, saw palmetto, and very small scrubby oaks and such. These areas frequently change (every few hundred/thousand years), and if you dug a foot or two deep in many of these coastal “desert scrub” habitats (10 miles from the beach), you’d find sea shells…

In my opinion, I believe that many species I find are actually genetically different from the same species found in north Florida and other southern states for those reasons… these “oak hammock islands” (if you please) have been separated from the other “islands” for thousands, possibly tens of thousands of years… the rest of the ecosystems I named above frequently change and could explain why most of the species I find in them are species that thrive in disturbed habitats.

Almost all forested areas in Southwest Florida were logged up until the late 1970s, so unless you’re in a conservation area or on private property, 99/100 times you’ll never be around a tree older than 30 years old…

Ok… so rant over… Here’s what you need to know about the specific collection
location for this observation:

Found under huge, old Live Oaks (Quercus virginiana), old Slash Pines (Pinus elliottii), and pretty old (but not as old) bald and pond cypress (Taxodium distichum and Taxodium ascendens). Sabal palms (Sabal palmetto) and saw palmettos (Serenoa repens) are also present, although if fires don’t take them out (until humans came into the picture wildfires occurred every 4-10 years), they generally don’t live too long due to Ganoderma zonatum rotting their trunks out… so the ones here aren’t too old (maybe 15-20 years at the oldest).

The property also contains invasive exotic species, mulberries, citrus, etc., but those don’t matter.

I sent you an e-mail too… but I hope this is more than enough info for you.



The oak…

is apparently “live oak.” Is that correct? Can you provide common English names and/or Latin binomials for the trees in the collecting area?

Very best,


Thank you, Ben.

This material has arrived in good order. I noticed some additional identifying numbers on the packet … 665(1732). Is any part of the former a collection number specific to the collection? I’d like to use your collection number on the website and in my herbarium data base. If the number has some other meaning (e.g., a site or grid position), then I will indicate no collecting number other than the MO observation number.

Sampling for DNA sequencing will be scheduled.

Very best,


Thank you.

I have plenty of spore prints and perfectly dried specimens. I’m actually sending out a few species to a couple different universities on Monday morning… let me know where to send some of these and they’ll be there!

I should also mention two other links for comparison:

But probably not A. jacksonii.

Please, please, please. This is a gorgeous set of photographs. I would love to see the dried material and sample it for DNA studies that are currently on-going.

Wow. The photos a really knockouts.

I suggest comparing




Very best,
