ENDODERMA 27 
The endophyte of the Cladophora, which occurs in smaller 
quantity under the same collection number as the Chaetomorpha, 
is certainly the same as that of the Chaetomorpha, though its cells 
may average a little narrower. In the Cladophora the parenchy- 
matous mass often surrounds the host continuously for a length of 
several cells; in the Chaetomorpha it less commonly wholly en- 
circles the host; in both of the hosts the cell membranes are 
remarkably thick, whether the endophyte is present or not. 
By the time that the zoospores (?) are set free, the overlying 
cuticle and gelatin of the host have often disintegrated and 
deliquesced to such an extent that no special beak or tube seems 
to be necessary to permit the zoospores to escape and none is 
developed, yet in other cases a pronounced = pesat prolongation of 
the sporangium is present.

Not collected by Dr. Coker, but it occurs in the type specimens 
of “Delesseria phylloloma Mont.," collected at Callao by du Petit- 
Thouars and preserved in the herbarium of the Muséum d'Histoire 
Naturelle of Paris, and, less copiously, in the type specimen of 
" Delesseria peruviana Mont.," brought from Callao by d'Orbigny 
and preserved in the same herbarium in Paris. Both of these
