Thank you to those who have suggested an alternative to A.rubescens – there is indeed a lack of ‘radish’ smell, and a lack of red blushing spots, so will propose another name until I find more/better specimens to post….

Lack of red blushing = not A. rubescens

Its either A. excelsa like Rod suggested or A. pantherina. Amanita excelsa is said to smell like radishes which seems to be the differentiating feature when compared to A. pantherina.

Since there are no reddish spots…

Since I don’t see any reddish spots or stains in these images or on the images in the very recent, previous posting from England labeled “rubescens,” I wonder whether they species involved might not be A. excelsa or something similar.

Lines circling the stipe’s bulb are often shown in illustrations of A. excelsa, and there are such lines in these photographs.

As an aside, I am looking for mature, documented (at least by a photograph) specimens of A. excelsa for my herbarium and to study in order to produce better reference material for the Amanitaceae website.
