We have received this material and it has been accessioned to Rod’s herbarium. We have scheduled it for DNA sequencing.

Thank you Garrett.

I certainly would be interested.

We are building up a library of DNA on, among other things, white-capped species of the Vaginatae.

Your material will make a very interesting addition to our data.

I suspect that your cap width is based on measuring across the bottom of the cap when it was “bell-shaped.” Send me an email via MO so that I can see your email address and send you a sheet of paper rulers (cm scale) that you can use to measure along the surface of the cap even when the cap has not expanded fully. When you do this, also measure the lengths of the striations on the cap edge (a range of lengths may be seen for the striations). This will allow us to compute a range for the ratio of striation length to cap radius…a useful macroscopic character.

Very best,


Red tint: I think it was an artifact

I will grab this one tomorrow. I will send it to you if you are interested, Rod.

Is the pinkish tint on the stem something that you saw with the naked eye or is it an

artifact of the camera. Since it seems to move about from picture to picture, I think it is probably in the camera.

This is very interesting looking.

The posting shows there is no herbarium specimen. Is that correct?

Very best,

Rod Tulloss
