but occasionally a considerable number will be found several inches 

 deep in the soil under an oak. The plants are dirty white or 

 tinged with a faint rosy color at first, globose, 1-2 cm. in size, and 

 when cut open have the appearance of being filled with grains of 

 sand. In one place I have watched for three seasons for a recur- 

 rence of hypogaei under an oak where this form was found in 

 considerable abundance in March, but nothing of any kind has 

 been found that would throw light upon the future development 

 of this species.
