I would be very interested in dried material if you should find this again.

The graying volva that is taking its time to collapse is something that should be explored further.

By the way, Geoff Kibby once sent me the European species, Amanita olivaceogrisea, from a site in the U.K. and pointed out how much it looked like A. sinicoflava. We have finally been able to get DNA from olivaceogrisea, and it supports the idea that the two species are rather closely related.

Very best,

was actually a bit more greenish than the camera recorded. But as it appears here, color seems closer to rhacopus. This was a mature fb, so I would expect the volva on a rhacopus to have more thoroughly disintegrated. Of course, maybe this is something other than either sinicoflava or rhacopus.

Cap color would be very unusual for sinicoflava
