is the name considered “nom. inval.” rather than “nom. prov.”?
clancy,
The graying upper part of the volval sack is not a character associated with A. vaginata.
In Scotland, I have personally collected a species that has a rather deep brown cap and a graying upper portion of the volval sack. This material has been incorrectly referred to Amanita submembranacea in the past.
After a review of the type collection of Amanita submembranacea var. bispora D. A. Reid (published in Mycotaxon in 1994), I concluded that the entity was an undescribed species. An invalid name was proposed for the species by Dr. M. Contu — A. castaneogrisea. The name has not been validated, but it is in use:

The picture at the site is a bit too dark, and the fruiting bodies are older than the ones in your pic; however, your pix and mine (from the Highlands and Islands Region) seem very similar to me.
Very best,
Rod
P.S. The range of “castaneogrisea” extends to Norway at least.
Contu (who doesn’t know the taxon so far as I know), simply proposed a name on the grounds that I had said it was a new taxon. Apparently, he was a bit hasty and didn’t fulfill the requirements of the Intl. Bot. Code of Nomenclature. Actually, I planned to use a different name; but Contu’s name is (occasionally) in use. I don’t want to change it just for my bruised ego. :) I will eventually validate Contu’s name.
