Chantransia Dumontiæ. A and B, young plants seen from above. C, plant with tetrasporangia, below hori- 
zontal and descending filaments. D and E, transverse sections of Dumonlia with Chantransia, showing endo-

The sporangia are most frequently sessile on the sides of the filaments, or 
they are placed on unicellular branchlets singly or two together, or lastly they
