2. Inmicroscopic structure. Both havea gleba of the same 
chambered structure, with basidia lining the chambers and bearing 
numerous (4-8) very minute spores. Both have a receptaculum 
of chambered structure, with walls of irregularly laterally inflated 
hyphe, the pseudoparenchyma. 
3. In biological adaptation for combining a safe early devel- 
opment with a good means of dissemination of the mature 
spores. In both the early development is subterranean, in 
the form of a compact egg covered by a thick gelatinous coat 
retentive of moisture and probably protective. When the 
spores are mature they are quickly raised above ground, and an 
attractive lure for insect agency in their dissemination is then 
offered by the fetid odor and saccharine composition of the 
deliquescing mass in which they lie, as well as by the bright 
colors of the receptaculum which supports them.” 
The differences between these two subfamilies are no less 
significant. They are shown: oe 
ek In the mature stage. The position of the gleba is out- 
side the receptaculum in the Phallez, while it is within that 
structure in the Clathree. The gelatinous layer of the volva is 
acontinuous sheet in the Phallez, while in the Clathree it is 
separated by the cortical plates into several more or less con- 
a masses, wholly separate from each other in Clathrus, but 
joing above into one in Anthurus.

the Phallez, the steps by which the lower and lateral portions
