In benthic samples from the unchannelized Missouri River, the diatoms Nitzschia dissipata (Kütz.) Grun., N. filiformis (W.Sm.) Schütt and N. pseudofonticola Hust. were observed within the mucilage tubes of four tube‐forming diatoms : Cymbella prostrata (Berk.) Cl., C. prostrata var. auerswaldii (Rabh.) Reim., Navicula tripunctata var. schizonemoides (V.H.) Patr., and Nitzschia filiformis. Microscopical observations of live and preserved specimens indicated that “invasion” by Nitzschia occurred primarily in older tubes. Data are presented on the environmental conditions in which the tube‐formers and their cohabitants have been found.
