We have received DNA (both nrITS and nrLSU) for this material that definitively identifies this as Amanita rhacopus.
This material has been received and accessioned to Rod’s herbarium. We have also scheduled it for DNA sequencing.
was found along the same trail as this present obs (177311)… not very far apart, as I recall.
These two collections (177310 and 177311) illustrate the complexity of the rhacopus-like taxa. To my eyes there is a real difference between the cap colors in the two taxa. Maybe there is a difference in the way volval fragments are left on the lower stipe. 177310 has a cap color like that shown in my original photographs of Amanita “sp-V03.” There is more yellow or tan in the brown of the cap than in the images of the present observation.
We need to find out if the apparent color difference is CONSISTENTLY matched to genetic differences. There is a lot of work to be done.
I am very grateful, David, that you are continuing to post these taxa and drying the specimens. Eventually, these efforts will support an improved understanding of the rhacopus-like group of taxa.
