This is a small mushroom, peculiar in having the young gills of a dark color and in the absence of any pink hues. The gills sometimes become moist and manifest a tendency to deliquesce. The drying specimens emit a strong but not unpleasant odor. Mr. Brændle says that their edible quality is excellent and that it is not impaired by drying. Peck, Bull. Torr. Bot.
