They are characterized by a white spore print, a small conical or bell-shaped cap, and a thin fragile stem. Most are gray or brown, but a few species have brighter colors. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like Mycena haematopus, exude a latex when the stem is broken, and many species have a chlorine-like odor (from Wiki).  See also Volbracht 1096. Stafleu 3968, Uellner 912.
