Panther Amanita

Something had started to eat this but the poison may have deterred them. Cap 7-18cm across, convex becoming flatter with a lined margin; creamy to whitish yellowish, darker in the center; smooth, sticky when moist, with virtually concentric rings of thin, flattened, cottony warts of whitish volval material. Gills free, close; white. Stem 80-200 x 8-20mm, hollow or stuffed and tapering slightly toward the top; white; smooth or finely hairy on the upper section, becoming strongly hairy and scaly toward the base; the white ring, which is above the middle of the stem, is often inverted and has a thickish, irregular edge that flares upward, then collapses and droops; the white oval-shaped basal bulb often has membranous woolly limbs with whitish cottony patches around its apex and the lower stem, and the volva sheaths the base of the stem like a stocking.
