Pileus 2-4 cm. diam., conico-convex to pulvinate, umbonate; surface at first covered by a dark chestnut to fuscous brown viscid pellicle which soon fragments, except at the disk, into a few large separable squamules on a white background. Margin entire, undulate, striate when moist. Lamellae free, white, ventricose, up to 4 mm. wide, crowded with lamellulae of two lengths. Stipe 3-4 cm. x 3-4 mm., cylindric, equal, fistulose, soon hollow; surface white, fibrillose, smooth, except for a few brown velar squamules towards the base. Veil unknown, no persistent annulus. Context white, unchanging, up to 4 mm. thick at the umbo, thin elsewhere. Spores 3.5-5 x 2.3-3 (4'3 x 2.6) μm, ellipsoid, hyaline, thin-walled, dextrinoid. Basidia 10-12 x 5-6 μm, clavate, bearing four sterigmata. Lamella-edge not recovered, cheilocystidia unknown. Pleurocystidia absent. Pileal surface a strongly agglutinated trichodermium consisting of cylindric elements, 2-6 μm, diam., with rounded apices.

Petch (1917: 310) regarded L. rhacoderma (Berk. & Br.) Sacc. to be a synonym but the spore characters are quite distinct.

菌盖直径2-4厘米,锥形-凸镜形起至垫形,凸顶; 菌盖白色,表面最初被深栗褐色至褐色的胶质结构覆盖,很快碎裂成数个大鳞片,菌盖中央的鳞片常保持完整。边缘完整,波浪状,潮湿时有沟纹。菌褶离生,白色,腹鼓状,宽达4毫米,密集,有2种长度的小菌褶。菌柄3-4cm×3-4mm,圆柱形,等粗,半空心,很快空心; 表面白色,纤维质,基部有少数褐色鳞片,其他部位光滑。菌幕未见,没有宿存的菌环。菌肉白色,受伤不变色,最厚达4毫米。担孢子 3.5-5 x 2.3-3 (4.3 x 2.6) μm,椭圆形,透明,薄壁,类糊精质。担子 10-12 x 5-6 μm,棒状,4小梗。菌褶边缘未恢复
(应该指干标本菌褶边缘未能复水成功),褶缘囊状体未知。侧生囊状体阙如。菌盖表皮由互相粘连缠结的毛状排列圆柱形细胞组成,直径2-6 μm,末端圆钝。

Petch(1917:310)认为L.rhacoderma (Berk. & Br.) Sacc.是该种的同义词,但两者孢子的差异非常明显。
