Scleroderma 
Speckled Puffball 
Plate 160. Figure 8. X i 
This pretty little puffball is not uncommon in the eastern 
United States on the ground in thickets and open woods. It 
differs from the common hard-skinned puffball externally in 
being much smaller and paler in color and having a much thinner, 
flexible peridium. It has been called Scleroderma tenernm by 
some, but whether S. tenerum Berk. & Curt, described from 
Cuba is meant or not, I do not know.
