(About 150:1.) others 95 //, and thinner and thicker parts were found in between each other. Another form is shown in Fig 403 a, b, c. This has also a vigorous basal disc formed by the through grow- ing of the lowermost cells. The cells in the vegetative part of the filament are nearly as long as broad, shortly The figure 402 shows one of these forms. It is fixed to the rocks by means of a vigorous basal disc; the basal cell is long with thick and lamellated wall; it increases in size and is formed by the lowermost cells of the filament gradually growing downwards into the cell below, a well known fact described by Rosen- viNGE^). The cells in the filament varies in length from about half their diameter to about as long as broad; they are rarely longer, but it happ- ens that cells occur about twice as long as broad. In this specimen the upper end of the basal cell is 67 /u broad; the vegetative cell in the filament are about 85 /j. broad and the emptied zoosporangia up to 150 fx broad. But I may point out that the breadth of the filaments is very varying, even in the same fil- ament; for instance was a filament in some parts 45 /u thick only, in.
