Erect ramified filament with sporangia-bearing branchlets ended with hairs. (About 150:1). As to the base I much regret that I have not been able to state with certainty how it is formed having only had a single specimen. By means of chlor- zinc jodine, which coloured the Acrochætium and at the same time had a clearing influence upon the tissue of the host plant, I have arrived at the conclusion that the base most probably consists of a few creeping filaments som

Erect ramified filament with sporangia-bearing branchlets ended with hairs. (About 150:1). As to the base I much regret that I have not been able to state with certainty how it is formed having only had a single specimen. By means of chlor- zinc jodine, which coloured the Acrochætium and at the same time had a clearing influence upon the tissue of the host plant, I have arrived at the conclusion that the base most probably consists of a few creeping filaments somewhat immersed in the tissue of the host plant. From this basal part an erect filament arises which im- mediately begins to give off bran- ches forming in this way a small tuft about 400// high. The prin- cipal filaments are rather straight (Fig. 63); they branch out in all directions along their whole length but mostly in the upper part. They consist of cells about 5—6// broad and 15—18// long. The chromatophore () is band- shaped often with more or less long prolongations along the wall of the cell; in the middle a large pyrenoid is pre- sent. The branches are of two kinds, short sporangia-bearing branchlets (Fig. 64) and ordinary branches growing out to filaments like the principal filaments and again branched in the same way. The branchlets have a very cha- racteristic appearance (Fig. 64). They consist of two or three, rarely more, cells the uppermost of which taper greatly and runs out in a long hair-like prolongation composed of two or three,.
