Notes:
Here I am again with the strange wetland Siberian Amanita (see observation 82957 and observaiton 82959)

We collected it in the Yuganskiy nature reserve in a transitional bog (Sphagnum, Carex, Betula, …) – yet another location along the Ob river basin, ~ halfway between the previous finds (Konda river and Novosibirsk). The specimen is in poor condition and reeks of smoke yet I’m very happy with this find: we spent a week looking specifically for this species because the place and time seemed appropriate (I joined a team of nature reserve workers who were sent to this remote spot to fight a big forest fire).

Just an idea – since genetically this species is close to A. friabilis, maybe we should look at A. hyperborea http://www.amanitaceae.org/?Amanita%20hyperborea as a possible match? Apart from the obvious morphological similarities (“the friabilis-lika A.vaginata / vaginata-like A. friabilis” with more or less subglobose spores), the location where the type specimen was collected resembles the preferred habitat of this species a lot (that’s how I found it this time).I think it would be interesting to compare these specimens with the type collection of A. hyperborea.
