Observation 13790: Amanita submembranacea (Bon) Gröger
When: 2005-08-15
Collection location: Lapland, Sweden [Click for map]
No herbarium specimen

Notes: Didn’t get a good shot of the cap, unfortunately. It’s somewhat zonate, darker brownish grey in the middle and has also a slightly darker zone where the furrows end, the rest is paler, yellowish grey, except for the paler margin. It was growing with birch and Salix. I have never seen it at a young stage.

Used references: Fits the description in Nordic Macromycetes, with the very grey inside of the volva, and the pinkish stem… A rather large species too, often reported from the northern part of Sweden.

They can explain why mine is paler than some of the ones I see when I google for pictures of it.

thoughts…

Irene,
Your photo and data point strongly to A. submembranacea. If the cap were a deep warm brown color and the volval limb were graying as in A. submembranacea, a name that is not yet validated might apply: A. castaneogrisesa (this name was intended by Contu to be a nomenclatural synonym of A. submembranacea var. bispora D. A. Reid). I thought O (Oslo) had at least one specimen that might be castaneogrisea. The latter species has often been called A. submembranacea in Scotland and northern England.
