It’s been a very interesting day going through about 20 of your collections with many

left to go.

Of course, I can’t really do IDs at such speed; but I am giving a little extra time to specimens for which the on-line image suggests a different name or is hard to “read.”

I’m very glad to know that you are interested to continue with the project for a bit longer. I think I will be able to send you a list of taxa that need not be collected further (unless it means getting a new “county of record” for the species). I will try to get such a “stop list” to you as soon as I can. You can probably guess at what it might contain.

One thing of which I thought there might be more was material similar to “citrina.” 2013 is the year to assemble as broad a range of citrinoid material as possible from North America because we have Dr. Hughes’ project related to the hybrid citrina to support with as much geographically diverse material as possible. You’ve probably seen my notes about this in MO postings.

When you begin to see “citrina”-like taxa this year, I would be very glad to get them to Dr. Hughes at U. Tenn., Knoxville, as soon as we can manage.

With regard to preservation, etc., the attempts at extracting DNA will tell the tale. If the material has been exposed to too much humidity after drying, we may not get good (or any) sequence data. In such a cases, one of the heat-sealing/vacuum-pack tools designed for home kitchen use may be valuable to us. I have no idea of the cost, but they might be worth getting.

More later, I’m sure.

Very best,


Glad you have the time to start looking at them Rod….

Last year was really my first year getting into Amanitas outside of the field guide species. You have helped me learn so much, so this year should only be better with a trained eye. There are so many species of Amanita in Southern Indiana hardwoods, and so many “rare” species occur with frequency once I know what to look for.

Please let me know how the drying/packaging was, and I will work to improve my storage methods this year as well. My focus will be on Amanita and Lepiota, so expect much more if you have the time.

How about…

multisquamosa for this one?

Thank you very, very much for the treasure trove of 2012 collections that you sent us several months ago. We are beginning to accession the material in the herbarium here in Roosevelt.

When I took this specimen out of its bag, I noticed the rolled sock type of universal veil on the top of the stem’s bulb. I then checked the spores; and they are inamyloid and ellipsoid.

The specimen belongs in Amanita section Amanita and may be close to “Amanita sp-S01.”

I’ll be posting many more comments on the many observations for which you have sent us voucher specimens.

Much more to come.

Very best,
