I placed these pictures here to extend the basis for solving the problem that you mentioned earlier in my A. vaginata var. alba (?) observation. Just wanted these gray specimens to complement the visual range of our white-pallid-gray Amanitas.

some remarks…

I am always interested to see postings identified as Amanita vaginata because I don’t have a solid concept of the entity behind this name. In the last 16 years I have been using the (admittedly) arbitrary idea that the microscopic anatomy of A. vaginata should be like that of A. vaginata var. alba. The latter seems to be identifiable by many Europeans in the field (once, the possibility of a given collection’s being A. islandica or A. arctica is eliminated…both have a flocculent sheath at the top of the stipe, which is missing in A. vaginata var. alba…as well as microscopic differences). On the other hand, given the many differing illustrations in field guides and the large number of names at the ranks of variety and form within A. vaginata, I find that I cannot distill a commonly held view of what A. vaginata is. Hence, my arbitrary decision about what properties the mushroom might possess. I would be very interested to receive opinions and “operating assumptions” about what A. vaginata may be…i.e., “candidate species concepts” for this important name.

European and west Asian specimens that have been identified as A. vaginata are also of interest to me IF they are WELL-PRESERVED AND ACCOMPANIED BY PHOTOS OF THE MATERIAL IN FRESH CONDITION AND ACCOMPANIED BY DESCRIPTIONS OF A DETAILED A NATURE AS POSSIBLE (e.g., based on the “field notes” form that I have posted on

Very best,

Rod
