Here are a few pictures of an "Amanita alba" which turned out to be something else, apparently. It fruits steadily (for an Amanita) in several spots around Akademgorodok, i.e. I've seen it more than once in each of those particular spots. It's a very generic-looking white Amanita sect. Vaginatae with two macroscopic features that are very confusing. First of all, it's not always white. Normally the fruitbodies are white just as you'd expect from A. vaginata var. alba, but in dry weather grayer fruitbodies appear, ranging from white with grayer center to uniform warm pale gray. Secondly, the volva - it has rusty stains like A. fulva. At first I'd thought it was a particular fruitbody affected with some disease but then I saw the same orange discolorations in other specimens from other locations (all within a 3 km radius). Also, the volva appears to be rather fragile, never forming a nice cleenex-like sack - there are usually some fragments at the base of the stipe and sometimes (but not always) some stuck to the cap surface.
