Tbe hosts afiFeeted were collected in considerable numbers about wet bogs or beside ponds; 
but the species seem very rare.

mentioned. It seems only remotely allied to any of the known genera, and is unique in that it 
produces from its basal cell well developed, ecmi-filanientous branching rhizoids (Plate IV, fig.
