Amanita Porphyria?

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Amanita Porphyria?

I saw this specimen on acid soil near Oak and Birch, between 5 and 7 cms across and my best guess was Amanita Porphria and wondered if this indeed might be the case. I have lightened the photo slightly from the original if by chance it aids ID.

In my limited experience of porphyria it has a much darker cap (with purple-violaceous tones: hence the name).
Could it be excelsa? Is the stipe above the ring grooved?
What was the volva like? Amanita (like Agaricus) can be very tricky and there are a lot more species than there used to be! Examination and description of all parts of the fruit-body is generally required along with shape and size of spores.

I agree with Roy on that the cap colour is to grey for A. porphyrea. Moreover, the ring of A. porphyrea is always coloured (at least underside) and very weak in structure so that it is soon completely adhearing to the stipe - such a stable white ring is typical for A. excelsa bvut would not appear in neither A. porphyrea nor A. pantherina usually.

best regards,
