(Fig. 104, A) ; the degree of branching varies greatly in the different species and even in different individuals. The lowest cell of the main C/rtrfo/)/;ora-filament is modified as an organ of attachment, has scanty contents, and is often considerably branched (Fig. 104, B). Basal attaching cells.
