Also Irene, for one reason or another A. pantherina is the most abused name out there. But so far we do have one clear A. pantherina on the West Coast that tends to be the same regardless of hosts (actually to complicates things a bit – two clades with 1-2 bp difference, but consistent within) – I see collections (including mine) from conifers, oaks and eucalyptus. The A. gemmata case is complex too, so we need to be very, very disciplined about marrying the molecular data with extensive morphology. I will have to look at my herb., but I think I have material from Sweden and Bulgaria. If not, may come begging for fruitbodies…

Looks close to the european gemmata

Also, several “pantherina” from North America seem closer to gemmata than to the real pantherina when sequences are compared. There’s quite some work do do here :-)

Amanita gemmata gr.

In the Amanita gemmata group indeed – hope to give you some better names in a few months to an year, or at least something to compare against based on molecular data matched by very good macro/micro morphology. We have at least two species in this group and the general section has not been studied properly in Western NA. There is a lot of molecular data that is not connected to good field data, but at least we’ll have a better grasp on distribution.

I agree with Alan….

These appear more like A. gemmata to me. We’ll never know for sure with this tiny photo of immature specimens and lack of info.
