The fungus is of a uniform smoky colour, the gills becoming 

 somewhat lighter in colour when mature, owing to the dusting of 

 white spores. Superficially resembling Omphalia umbellifera, Fr., 

 more especially the dull green form of that species, differing, 

 however, in its smaller size, the absence of striae on the margin 

 of the pileus, and its smaller spores.
