Summary
Lobocolax deformans Howe was found to be a bacterial gall onPrionitis lanceolata. Rodshaped bacteria were distributed throughout the gall in intercellular locations. Algal cells in the gall area exhibited numerous proplastids and irregular cell walls. Bacterial cells were also found in galls located onPolyneuropsis stolonifera (gen. et sp. nov.).
These elongated and sometimes branched bacteria occur primarily in the outer areas of the gall. As inLobocolax the cells contained numerous proplastids, however, a large increase in the amount of ER was also noted.
