Description
- Cap: 4 – 11 cm wide, hemispheric at first, then convex to plano-convex, deep brown to hazel-brown to pale ochraceous brown, densely distributed warts that are pure white to sordid cream, minutely verruculose, floccose, easily removable. Viscid when wet, with a short striate margin. The flesh is white, unchanging when injured.
- Gills: free, close to crowded, white becoming greyish, truncate.
- Spores: white in deposit, broadly ellipsoid to ellipsoid to elongate, infrequently globose. 8 — 12 × 5.5 — 8 µm.
- Stipe: 5 – 14 cm long × .6 – 2 cm wide, subcyclindric, somewhat narrowing upward, white, becoming slightly tannish in age, stuffed then hollow, finely floccose becoming smooth above the ring, and with small appressed squamules or creamy floccose material below. The volva is white, becoming grey with age, forming one or sometimes two narrow hoop-like rings just above the bulbous base. The flesh is white, unchanging when injured.
- Odour: Unpleasant or like raw potatoes
- Microscopic features: Spores are 8-14 x 6-10 µm, smooth, elliptical and inamyloid.
Other than the brownish cap with white warts, distinguishing features of Amanita pantherina include the collar-like roll of volval tissue at the top of the basal bulb, and the elliptical, inamyloid spores.

Famous quotes containing the word description:
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
