Description
Gametophytic thalli tubular, consisting of small, rounded, irregularly arranged, widely spaced cells, often paired or in fours; monoecious, isogamous. Sporophytic thallus codiolum- or cyst-like. Tubular thalli arising from both aplanospores and zoospores with a distinctive development in which basal, non-septate rhizoids from the initially uniseriate filament are transformed into sep- tate uniseriate filaments, which then develop basal non- septate rhizoids; this pattern repeated to yield a tuft of up to 50 fronds. From other tubular green algae it differs in the primary structure of the nuclear encoded small subunit rRNA gene and the ITS regions.
