These have a single cilium, and bore their way into the host-cell. After entrance, they produce a plasma-mass, which becomes enclosed in a delicate membrane. The cell so formed sprouts at its uppermost pole, and gives rise to a new spherical cell, into which the older discharges itself. In the second cell numerous small sporangia are formed, so that it represents a sporangial sorus; beside it is always found the empty membrane of the first cell. The sorus breaks up later into single sporangia, which on opening, set free their contents ^Schroeter, " Pflanzenparasiten aiis d. Gattung Synchj';' Cohn's Beit); z. Biolog. d. Pflanzen, 1S75.
