When young the plant is filamentous composed of a single row of cells. These in the young filaments are disc-shaped (Fig. 5 c), their length being much shorter than the breadth, often only a fourth in the newly divided cells. They are divided by horizontal walls and all cells are capable of division. The diameter of the fila- ments is about 35 The base of the plant consists of an enlarge- ment of the lowermost end of the basal cell, forming in this way a small disc by means of which the plant is faste- ned to the substratum (Fig. 5 h). I have not seen any rhizoids grow- ing out from the lower- most cells as is the case in Bangia. In the somewhat older filaments the cells now and then begin to be divided also by longitudinal or more or less oblique walls. This division of the cells is rather irregular; in some plants nearly the whole filaments are divided, in other we find parts of the filaments divided into many. Fig. 5. Bangiopsis subsimplex (Mont.)
