Anabaena

Anabaena Planktonic filamentous algae recognisable by their beaded appearance, often curly, and sometimes having thick walled clearer 'heterocysts' (specialised cells) and sausage shaped dense spores at intervals. Cells up to 10um across.Common in the plankton of lakes and ponds, but sometimes occurring in bogs. The figures show parts of two filaments at different magnifications.

Stigonema

Stigonema The filaments branch irregularly, and usually from dark furry masses on damp rocks. The cells are rounded, and lie several abreast in the older parts, as shown. Heterocysts scattered, but are not regularly at the bases of branches. The cells vary from 3 to 30um in diameter, but of course the older parts of the plant are very much wider than this. 110a, part of whole plant x20; 110b, tip of a plant showing irregular rows of cells surrounded by mucilage...
