I think that “getting it right” with the Vaginatae is something that will…

not happen in my life time. At first, it seemed to hard for anyone to attempt, and I didn’t even collect Vaginatae. Then I though I’d found some useful methods for separating taxa with microanatomy; so I began to work on the section. In the last four years, I’ve been trying to work on the__Vaginatae__ from a genetic point of view thanks to many helpful colleagues.

We constantly find new sequences implying that there are many more species than I had ever thought there might be.

One of my friends said, I should no longer express happy surprise upon finding a new species. He said that he preferred to think to himself. “Oh, another one. Big deal.”

I prefer to think that I might someday see the growth in the number of possible begin to slow down…but that may not happen in my lifetime.

There are a large number of Vaginatae out there. A very large number.

Very best,


Wrong again!

Hi Rod,

Since it seemed to match up every other way, I just assumed it was a normal variation in color. What species would you suggest it is?

One of these days I’ll surprise you and get it right!



Hello, Brian. >>EDITED

I don’t think there is enough orange in the pileus coloration for this to be fulva or amerifulva or their ilk.

ADDED: Also, there would be orange stains and spots on the exterior of the volval sac if this were the above mentioned species.

Very best,
