Helminthocladia — Doty and Abbott 
63 
species are similar to each other in that the 
branches near the tops of the filaments are often 
trichotomous. The ultimate cells of the cortical 
filaments are more crowded, therefore, than those 
of most other species. Often in this genus where 
the cortical filaments are not dichotomous the 
production of carpogonial branches or rhizoidal 
branches (of the type illustrated in Fig. 18) 
seems to have been involved. Either normal 
carpogonial branches may have appeared (Figs. 
20 cp, 23 cp) , or abortive carpogonial branches 
may have become reorganized (Fig. 20v), pos- 
sibly into vegetative branches.
