The Taxonomy Of Pyxidiella Curvicaula (Penard)



The Taxonomy Of Pyxidiella Curvicaula (Penard)



Journal of Protozoology 11: 552-554



The peritrich Pyxidiella curvicaula (Penard) was observed in the activated sludge of an English sewage works and was successfully cultured in the laboratory. A number of observations were made upon clonal cultures of P. curvicaula which indicated that this species is colonial at one stage in the asexual life cycle. The branching of the colonial adult is more complex than originally described, and a maximum of 17 individuals has been observed upon one stalk. Since P. curvicaula is in reality a colonial peritrich, it should therefore be transferred to the genus Opercularia Stein, with the name of the species changed to Opercularia curvicaula.
