The Chordariaceae are a species-rich family of brown algae from the order of the Ectocarpales . The representatives of the family are found grown ( benthic ) on stones or other algae on the seashore.

description

The sporophyte forms an olive-green to brown, thread-like or stem-round thallus , which can be branched simply or irregularly in tufts. It is attached to the ground with a crust-like adhesive organ made from compact threads. The upright branches consist of a single to multi-stranded central medulla of elongated cells, which is surrounded by a cortex of radially protruding, simple or branched, smaller cells. These cortex cells contain several plastids with a pyrenoid, this is where photosynthesis takes place. Some members of the family also have an intermediate layer of unpigmented cells. The gametophytes are also thread-like, but often smaller, sometimes microscopic.

Systematics

The Chordariaceae family was established in 1830 by Robert Kaye Greville (in Algae Britannicae, p. 44). According to Algaebase (August 2019) the family comprises around 500 species in more than 100 genera:

use

In Japan, several species of the Chordariaceae are consumed as Mozuku algae vegetables. The species Ito-Mozuku ( Nemacystus decipiens ), Okinawa-Mozuku ( Cladosiphon okamuranus ), Ishi-Mozuku ( Sphaerotrichia divaricata ) and Futo-Mozuku ( Tinocladia crassa ) are cultivated on the coasts .
