Amanita excelsa var. spissa is a variety of basidiomycete fungus of the genus Amanita .

Description

The cap is around 10 cm in diameter when fully expanded, and is various shades of brown or brown/grey, sometimes washing off to buff. Younger specimens have grey veil remnants often in quite large; flat patches, but these are usually removed later by the weather. The mature stem is usually fairly long, and has a bulbous base which is without a discernible volva, having just several flaky ring zones instead. It is marked above the ring with vertical lines. The ring is large and white, and also has lines. The gills are crowded; white, and have a slight decurrent tooth. The flesh is white; smells of radish, and turns purple when H2SO4 is applied. [1]
