Description: Basidiocarps medium, solitary to subgregarious. Pileus 50-80 mm, convex to piano- convex, then plano-depressed, margin appendiculate with friable volva remnants, tending to be lost with age, pale buff, buff or sordid buff, viscid when young or wet, drying with age, volva remnants forming a thick covering of pale greyish sepia to pale smoke-grey warts, either isolated or connected at the base to form sheets, easily removed when handled, tending to litter the surrounding soil, and leaving a reticulate pattern of shallow depressions. Lamellae crowded, free, 5-11 mm wide, white; lamellulae subtruncate. Stipe 80-97 high, 9-20 mm diameter, solid, from clavate to bulbous, occasionally radicating base, 22-44 mm diameter, surface above annulus white, sparsely floccose or breaking into fine bands, below annulus white to very pale smoke-grey, finely scaled, at base volva remnants forming con- centric rings of thick, fleshy scales or warts, rarely forming spurious ring below annulus. Annulus friable, finely striate, tending to break up into sections and often lost, white then pale luteous. Context of pileus and stipe white.
Spore print white. Basidiospores (40/4), 9-12 x 5.5-8 µm, Qm 1.55, Q 1.31-1.91, ellipsoid to elongate, hyaline, amyloid. Basidia 41-59.5 x 10.5-13 µm, 4-spored, clamped. Lamella margin cells numerous, 16-31.5 x 10.5-16 µm, clavate, hyaline (seen only in Ridley 576). Pileipellis composed of 50-70 µm wide, gelatinised suprapellis, and non- gelatinised subpellis. Volva remnants from pileus composed of chains of small byaline, globose to ellipsoid cells, 16-31.5 x 9-19 µm at tip; at base, cells larger, 17-66 x 14-5-39.5 µm, intermixed with hyphae to 9 µm wide. Clamp connections abundant.
