Amanita excelsa for the species, and A. excelsa var. spissa as the variety.

I proposed deprecation of A. spissa in favor of A. excelsa.

Amanita excelsa and Amanita spissa

Since you have an ID from a European mycologist, I would just suggest the name Amanita excelsa as the currently accepted name for the species. I agree the species is very variable. I am aware that in southern Europe, French mycologists (as an example) have periodically recognized many varieties of A. excelsa. In the most recent treatment by Neville and Poumarat (2004. Fungi Europaei 9: beginning on page 710), they gave at least some support to 3 forms and 2 varieties of excelsa. At least one of the forms (all white or whitish) may just be based on albino specimens (for example) rather than having taxonomic value. The epithet spissa is applied at the level of variety by N&P; however, my mentor, Dr. Bas, has reported a “fairy ring” in which both the spissa fruiting body form and the excelsa fruiting body form were simultaneously present. This suggests that taxonomic segregation is not appropriate.

I think it is a very variable species that grows mostly under conifers. It was identified in a farm I own in central Portugal by a micologist.

these are beautiful amanitas…
