I would love to be able to send you the dried material, however I’m leaving the country soon and won’t have time. I’ll keep this in mind for the future when I return to NH.

We have not found any evidence that A. ceciliae occurs in North America…

but we have found that we have several species that do not yet have formal names, and these taxa look like small versions of the European A. ceciliae. Among these taxa are several that are treated on the “Amanitaceae Studies” website.

Their ranges overlap and they are difficult to tell apart using only images.

Here are some references:

http://www.amanitaceae.org?Amanita%20rhacopus
http://www.amanitaceae.org?Amanita%20texasorora
http://www.amanitaceae.org?Amanita%20sp-V03
http://www.amanitaceae.org?Amanita%20xanthomitra
http://www.amanitaceae.org?Amanita%20sp-QUE03

These pages provide links to others. We have accumulated evidence that there are around 15 species in this group.

In New Hampshire, you are most likely to have Amanitarhacopus” or A.sp-QUE03.” Both of these probable species occur in Maine and in Quebec.

So far we no DNA from New Hampshire material. If you would like to contribute dried material to our study, we would be very happy to have it since NH is not covered by data in our study.

If you would like a workbook related to collecting, drying, and studying amanitas, you may email me via the MO email function. I’ll then know your email and can send you a pdf of the workbook.

Very best,

Rod Tulloss
