Based on chemical features: Based on chemical features: This collection shares a common nrITS sequence with two others from Maine and one from the Island of Newfoundland. The pinkish tint to the cap is present in some of the collections and not very strong in others. Some of the collections were mistaken for A. rasitabula in the field and others for A. homolae. This provisional taxon is erected to hold this material which is genetically distinct from both homolae and rasitabula.

Brown’s “Composition of Scientific Words” (Smithsonian Institute) is a very enjoyable book. Open to any page.

Very best,

Rod

Happy New Year, Rod.

January seems apropos for learning about the Frost Rose Ringless Amanita.

Hello, David. Happy New Year.

I think it may have a restricted range. We have one collection from Newfoundland (from Dr. Andrus Voitk) and three from Maine (three different counties and three different collectors. I know of no material south of the Atlantic boreal forest in Maine…on the other hand, the exploration of the Vaginatae is just leaping into being.

I’m snowed under with work, but am trying to get a page started here:

The “Frost Rose Ringless Amanita.”

Very best,

Rod

Nice one, Igor!

Must be a rare species. I don’t see it documented on the AS website. Photos appear to capture the subtle pink mentioned within the notes.

Thank you, Igor.

This material has been accessioned in our herbarium.

Very best,

Rod

Then there is a chance that this is homolae.

Thanks for letting me know on that point, and thanks for the plan to send the dried material.

Very best,

Rod

the gills did turn the pale salmon color upon drying! You shall have the material in a few days.

This reminds me of Amanita homolae when I first saw it in Maine…years ago.

Did the gills turn pale orange or pink when they dried?

I’d be very, very interested to see this material. I may have a chance to get some material of sect. Vaginatae sequenced. This looks like an interesting candidate for that project.

Very best,

Rod
