We had some difficulty with sequencing, but we were able to derive an nrITS…

…sequence. It differs fro the sequences we have for Amanita albemarlensis in only one character of 672—-0.15% genetic distance. Although your material is older and colors have changed, I think we should call this Amanita albemarlensis.

We have had difficulty with sequencing albemarlensis in the past. So this is not new in dealing with the species.

A very interesting find. This is a first record for Kentucky.

Nice photos, too.

Very best,


Can’t wait !

Thanks for the link. I’ll send it out asap.

I would like to look at the available specimen or part of it.

This species is very similar to Amanita jakeslandingensis nom. prov.

There are other zonate-capped Vaginatae in the eastern U.S. also.

I’d like to see what DNA can tell us about this specimen.

Very best,
