Baisidlocarps small to medium, solitary to gregarious. Pileus to 85 mm wide, margin entire, 'sulfur-yellow' with a 'greenish' tinge, and 'brown' radiating fibrils, or 'greyish' with 'brown' tints, paling at edge, with faint radial markings, silky smooth, without volva remnants. Lamellae crowded, free, 6-12 mm wide, white; lamellulae subtruncate. Stipe 70-80 mm high, 12-19 mm diameter, hollow, from clavate to bulbous base, occasionally pointed, 28-32 mm diameter, surface above the annulus faintly striate or pulverulent and white, below annulus sparsely floccose, white, with a free, white, fleshy volva limb, or an oppressed, membranous volva limb which tears irregularly. Annulus membranous, finely striate, margin finely serrulate, pendulous, white. Context of pileus white or slightly coloured under the disc, stipe white.

Spore print white. Basidiospores (20/2), 8-9(-10.5) x 6.5-8.5 µm, Q^m 1.12, Q 1. 06-1. 30, subglobose to broadly ellipsoid, hyaline, amyloid. Basidia 34. 5-5 1. 5 x 10.5-13 µm, 1-4-spored, not clamped. Lamella margin cells numerous, 20-50 x 10.5-22.5 µm, mostly clavate, hyaline. Pileipellis up to 380 µm wide, non or only very slightly gelatinised. Volvo trama regular, hyphae to 15 am wide, and rarely, enlarged terminal cells.
