Stipe x 0.7 cm., tapered upwards, covered with greyish-brown fibrillous striations on whitish ground; fibrils cracking into blackish-brown scales all free above and attached below, both above and below the blackish-brown ring; slightly hollow above, and quite hollow and chambered towards the base. Volva white with ochraceous tints, blackish-brown round margin which is adpressed to the base of the stipe. Spores non-amyloid, spherical 9-10 um diam.
