Agaricus revelatus Berk. & Br. in Journ. Linn. Soc., Bot. I I: 510 (1871).
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。
