This is already one of the observations for which I have made sure that sampling…

for DNA is moved up in our queue. The excercise of entering all the herbarium accession numbers on MO is very good at revealing vouchers that have not gotten the priority that they should have had.

Mea culpa.

from the same exact location as the cyclops specimens seen on the Amanita Studies website. Contrast between the darkness of the disc and the lighter marginal cap surface not as pronounced as in (at least some) other cyclops collections. Strongly tuberculate-striate margin with long deep striations matches other cyclops observations.

Then the effort to sequence it will be particularly interesting.

Lots of things that are grayish with globose spores have been called vaginata in North America over the years. It will be interesting if we could make a dent in understanding something about the “group” of such taxa.

Very best,

the same species as obs 248445, which had spores subglobose to globose, and thus is unlikely to represent rooseveltensis. I’m pretty sure this and 248445 were found in the exact same location on my property, a few square yards where Amanitas representing four different sections have been collected.

This material has been scheduled for sequencing with raised priority.

Hello David,

This material has been accessioned into our herbarium.


No problem, Rod.

I’ll dry these, and the section Amanitas I just posted, and mail them together with all the other MO catalogued stuff I get this year. Like before, I’ll mail it all sometime in the fall. Then you may take your time about getting to stuff.

I think you may be on target about there being lots of stuff to keep you busy at NEMF. North central Jersey and the eastern slopes of the Poconos are coming off a real nice 3 week period of weather. On my way to Stroudsburg, I’ll stop at a spot in the Poconos and see what I can find.

Dave, I’m swamped.

I’d like to see this baby, but I can’t keep straight in my head all the great stuff that you and others post on MO. With regard to what to bring along, I’ll have to leave it in your hands. We will have boxes in which we can take specimens home (an innovation of Cristina’s). With all the recent rain, we are a bit worried about being completely overloaded during the foray.


I’ll arrive at NEMF on Friday morning.

Anything you’d like me to bring along?

Will you attend NEMF

I’ve found and posted this type in the past.

I have the material ready from those previous collections. The large specimen from this latest collection is drying. It’s a really beautiful specimen.

Waiting for some spores from the smaller cap. Left two patially buried buttons and will check tomorrow.

Very interesting.
