that in deciding which species to compare with “rhacopus,” I eliminated all of those that have a volva that is other than white before the graying or other color change occurs.

Very best,

Beautiful, but probably not “rhacopus,” Walt.

Just in the last day, I posted another species on WA) in the “rhacopus” group.

The new taxon is here:

http://www.amanitaceae.org?Amanita%20sp-N61

Another member of the “group” with a cap color somewhat similar to that in your photo is here:

http://www.amanitaceae.org?Amanita%20sp-V03

To illustrate that some of these taxa can be separated from some of the others by spore data alone, I set up (on the technical tab of the “rhacopus” page) sporographs comparing the spores of “rhacopus” with a group of the other taxa that are separated morphologically and/or molecularly from “rhacopus,” as of this morning.

The sporographs “stream” data from the database that underlies the web pages. Hence, if I change spore data for some species, all the sporographs on the site that include a graph representing that spore data are immediately updated to reflect the change. Nice feature thanks to David Tulloss.

The “rhacopus page” is here:

http://www.amanitaceae.org?Amanita%20rhacopus

Since the data sample sizes are all pretty small at the moment, there will be some changes in the graphs before they stabilize.

Very best,

Rod
