Hello, Nathan.

This is another thank you related to the present observation.

Dr. Karen Hughes is finalizing a paper on this genetically curious species (that flat out “refused” to have an easily accessible barcode). MO played an important role in gathering material for Dr. Hughes’ study. The voucher for this observation provided good data, and the collection is cited in the paper. Thank you very much.

Very best,

Dr. Hughes is wrapping up her current project.

There sill not be the possibility of more DNA sequencing based on future collections. The good thing about the lavendula group is that the three taxa that will be recognized can be segregated by spore size and shape. In other groups including taxa found by molecular methods, we have not been so lucky as to have spores provide a morphological means of separating what appear to be different taxa from a molecular point of view.

You’re very welcome.

There will probably be at least two more papers on the lavendula group in the next year or two.

Very best,


Thanks Rod!

Sorry for the slow response. Got buried in the flood. Great to hear that this was valuable. Should I let you know about any future collections I make?

Hello, Nathan. Your material was sequenced…

…courtesy of Dr. Karen Hughes and turns out to be the infraspecific hybrid taxon that she has been studying. This is the second site on Cape Cod for the hybrid.

Thank you very much for contributing this material to our project on the purple-staining citrinoid amanitas in eastern North America.

Very best,


Thanks Nathan,

This material has been received and accessioned into Rod’s herbarium, we have also scheduled it for DNA sequencing

Thank you, Nathan.

I’ll have my eye out for this package. At the moment, we are moving 30 or more samples per week out to our sequencing partners. This means that new material of citrina like taxa is getting relatively quick turn around (a few weeks if all goes well). We’ll keep you up to date on outcomes.

Very best,


Finally got it shipped yesterday!

Let me know what you learn about it. Also let me know if you put it under another id number so I can keep track of it.

Yes, the Herbarium Rooseveltensis Amanitarum…

will be pleased to watch the P. O. Box for your shipment.

Thanks, Nathan.

Very best,


Hi Rod

Yes, I have the specimen right here. Should I send it to the PO Box I have for Herbarium Amanitarum Rooseveltensis, or do you want it sent somewhere else?

Do you still have the herbarium specimen for this collection?

If you find this again in 2013, it would be great if you could dry it and post on MO about it.

This year there is a project to obtain “citrina-like” specimens from as much of North America as possible, for DNA analsysis.

Very best,

Rod Tulloss

Thanks Rod!

I’ve manage to get out occasionally, but not much. Looking at the other observations on MO, I see what you mean about the lavender/purple coloring. Thanks!

You probably nailed it Nathan, but that’s not the typical lavender/purple coloring…

that’s the gray-pink mixture typical of the volval material. (I hasten to add that I’m reporting what I see with these old eyes.) If you have been collecting in Falmouth, then you must be able to get out and about. I hope you didn’t experience too much damage from the storm.
