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 be- 

 come moist and manifest a tendency to deliquesce. The drying speci- 

 mens emit a strong but not unpleasant odor. Mr. Braendle says that 

 their edible quality is excellent and that it is not impaired by drying.
