The delicate ring on the upper part of the stipe is a remnant of the partial veil that extends from the cap margin to the stalk and covers the gills during development. The bulb at the base of the stipe is spherical or nearly so. The surface, in young specimens especially, is frequently fibrillose (covered with small slender fibers), or squamulose (covered with small scales). Stem thick, solid and tapers slightly upward.
