BRIEF DESCRIPTION: The cap of Amanita pilosella is 25 - 70 mm wide, convex to plane or somewhat concave, sometimes slightly umbonate, dry, umber, fuliginious or grayish brown, paler on expansion, with a smooth to faintly striate margin.  The cap has innate, dark fibrillose streaks, minutely dark grayish-brown, fibrillose-subvillose, especially toward the margin, with powdery-subvillose, umber, fuliginous or blackish remnants of volva.  The remnants of volva form a scurfy-pruinose covering, especially near the margin, or thin, flat patches or irregular warts and sometimes conical warts on the center of the cap.

The gills are free, crowded, white or grayish-white.

The stem is 40 - 110 x 3.5 - 6 mm, attenuate upward, solid, entirely gray, fuscous-gray, grayish umber or fuscous with dark fibrillose, innate streaks, subfibrillose to subflocculose and grayish patches above the ring.
