Chaetophorales

Very young specimen of an epiphyte on Oedogonium. The setae (filaentous hairs) are not yet grown. Pyrenoids are visible and bacteria living as epibionts.  Aufwuchs on Oedogonium which itself was Aufwuchs on roots dangling in a creek´s water. This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Portrait (lateral view) of the chaetophoralean alga, Aphanochaete repens (Braun, 1849). A. repens is epiphytic on filamentous algae (in this case Oedegonium). The cells are cylindrical to cuboid, some bearing one long clear seta with a bulbous base. The cells arrange themselves in files with short branches along the long axis of their host algal filament. Collected from a freshwater pond near Boise, Idaho June 2004. DIC optics.

Chaetophora is a branched filamentous alga wholly embedded in mucilage. The species shown forms pads which can grow large enough to be visible to the naked eye as green, jelly globes adhered to stones or plants. The mucilage is a protection against ingestion. On the surface of this jelly globes one can see a lot of colorless cells formed as hairs (chaetae) projecting out of the jelly. This cells contain no chloroplasts and serve for nutrient uptake.  The bright field photo doesn´t display the mucilage. This young specimen showed only two projecting cells (see inserted picture). The arrow idicates a pyrenoid within a chloroplast.  Collected from Bodden, the brackish waters lying between the isles of Hiddensee and Ruegen (German Baltic Sea). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Chaetophora is a branched filamentous alga almost wholly embedded in mucilage. The species shown forms pads which can grow large enough to be visible to the naked eye as green, jelly globes adhered to stones or plants. The mucilage is a protection against ingestion.

Stigeoclonium starts branching. The tiny filamentous extensions don´t belong to the alga but are cyanobacteria of genus Chamaesiphon.  Aufwuchs on Oedogonium which itself was Aufwuchs on roots dangling in a creek´s water. This image was taken using Zeiss Universal with Olympus C7070 CCD camera.   

Portrait of the filamentous green alga, Chaetophora elegans (Roth; Agardh, 1812). Globular or lobulated colonies are embedded in a gelatinous matrix. The branching filaments terminate in tapered tips or long thin multicellular hair-like projections seen on the left in this image. The cells are cylindrical, containing a single parietal chloroplast and one to several pyrenoids. Branch filaments and axial filaments are similar in appearance. Collected from a freshwater pond near Boise, Idaho October 2004. DIC.
