Chordariaceae is a family of brown algae. Members of this family are may be filamentous, crustose with fused cells at the base, or they may be terete and differentiated into a central medulla and an outer photosynthetic cortex. They have a sporphytic thallus usually aggregated to form a pseudo-parenchyma.Pound, F. E. 1962 The Biology of the Algae Edward Arnold Ltd.
As their general name suggests their pigmentation is brown.
