Algal factsheet: Stigeoclonium (Chaetophoraceae)


Diagnostic features

Branched filamentous chlorophyte with branches ending in pointed cells. Branches are one cell thick, and subbranches are similar width; there is no substantially wider main stem (cf. Draparnaldia).  Non-terminal cells are usually cylindrical, but may be barrel-shaped (a mixture may occur in the same material).  Each cell contains a single green chloroplast, which is a parietal band (cf. Cladophora).  Filaments are not embedded in mucilage (cf. Chaetophora). There is a prostrate basal system of filaments that provides attachment to the bed.

Typical habitats

Fast flowing, stony bottom habitats, including nutrient enriched streams

Notes

Can co-exist with sewage fungus
