We have accessioned this material to Rod’s herbarium and scheduled it to be sampled for DNA sequencing.

I look forward to seeing the material you mention.

When I have initial data providing surprises such as hidden taxa within a species concept that once seemed so simple and easily understood, I really regret the specimens of the “common species” that I did not make or did not dry or did not document. There is always some practical matter (lack of time, lack of dryer space, lack of some resource or other) that causes me to restrict what material I collect at a given time or during a given period. One can always reliably predict that the decisions will be rued in the future.

Very best,


On eastern tawny grisettes…

Hi Rod, I would not normally be too interested in keeping or posting specimens of vaginatas or tawny grisettes but I know you’re really interested in and working hard on some of them right now. This one was very pretty and a perfect specimen but to the naked eye had nothing especially remarkable about it. The color was quite a bit more pale than the richer tawny brown I often see. Nice saccate volva but not greying as in A sinicoflava. I hope the specimens collected this week come off the dryer in good shape. They were collected in 100 degree weather and I did my best to keep them cool during the long drive back home; they went immediately onto the dryer before I went to bed and thus I gave it the ol’ college try.

I don’t think that this is in the fulva-amerifulva “group,” too much olive.

The fulva-amerifulva “group,” at present, I’d suggest would include fulva, fuligineodisca, and two unnamed, eastern North American taxa that are distinguishable by gene sequencing. I am very interested in receiving documented, fulva-like material from any geographic region except the Island of Newfoundland, the Adirondack Mountains in New York, eastern Connecticut, the Czech Republic, and Central New Jersey.

Was there any sign of the volval sac turning gray?

I think this material would be valuable to our research, Britt.

Thanks for the posting.

Very best,
