There are a goodly number of taxa that are look-alikes to rhacopus. So far, they are not hard to separate genetically. The group, as a whole contains many taxa that seem to have had a common ancestor, which (given the data on other species of Amanita) may have had an East Asian origin…based on methods that exist at present and using the limited number of genes that have been in use for the purpose.

Very best,

Rod

Thanks Rod.

Does molecular evidence point toward the possibility of any “split-off” species that resemble rhacopus?

DNA sequences came back this week and confirmed ID very nicely.

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

I’m very interested because of the apparently rather pallid cap color.
