Subclass EUFLORIDEAE, 
CONSPECTUS OF THE ORDERS. 
N emalioninae. 
Fertile carpogonial cells evolving into the gonimoblasts, which form erect 
branching tufts, sometimes laterally expanded. Gonimoblasts themselves 
sometimes confluent with contiguous cells of the thallus or with auxiliary 
cells. 
Gigartininae. 
Fertile carpogonial cell or short processes fusing with the auxiliary cell, 
so that the gonimoblast filaments evolve inwards from the fusion cell so 
formed. Carpogonial filaments articulate and auxiliary cells binate, mostly 
formed in a procarp proper, rarely occurring singly in the thallus. 
Rhodymeninae. 
Fertile carpogonial cell or short processes fusing with the auxiliary cell, 
so that the gonimoblast filaments evolve towards the exterior region of the 
thallus from the fusion cell so formed. Carpogonial filaments articulate and 
auxiliary cells binate, usually formed in a procarp proper. 
Crypt oneminae. 
Fertile carpogonial cells situated within the thallus, emitting elongate 
filaments, often branched, the terminal or intercalary cells fusing with 
auxiliary cells. Gonimoblasts evolving from the fusion cell so formed, 
inwards or outwards. Carpogonial filaments and auxiliary cells formed 
singly in the thallus.
