LycOPERDON, Tournef. (emended). 
Peridium double, external layer (cortex) becoming broken up 
into subpersistent warts or spines, inner layer smooth, dehis- 
cing by a small apical aperture, or the whole of the upper 
portion evanescent. Capillitium dense, threads usually 
branched, with tapering ends, smooth ; sterile basal stratum 
present ; spores globose or elliptical, epispore rough or smooth.

Up to the present the distinctions between Ly coper don and 
Bovista have been drawn chiefly from external characters, 
and more especially depending on the nature of the outer 
layer of the peridium, which more extended observations 
have shown to be valueless from a generic point of view. If 
it is necessary to keep up the two genera, the distinction 
must be founded on the presence or absence of a distinct 
sterile basal stratum, and this character, while dealing only 
with restricted localities, appears reasonable, but when an
