Your measurements make a sporograph…

That fits inside my sporograph for argentea. Because of the physial appearance and the ellipsoid spores, I’d suggest A. argentea for this collection.

Do you have enough dried material to spare me a piece? I’m interested to see if (and how) our spore measurements differ. Part of it is that my measurements are a composite of spores from many collections in different states of preservation and conservation. But I don’t think that that is the whole story.

Very best,

Rod

The squat stature of the mushroom in the first image reminded me of dried…

material that I borrowed in the past from European herbaria…Amanita argentea. It is still the case that this species is mistakenly identified with A. mairei in some books. They both have unusually narrow spores for European Vaginatae, but they are far from identical.

If you should find this creature again, spore measurements would be very useful in finding if you have argentea.

Very best,

Rod
