Taxonomy
Kingdom:Plantae
Phylum:Chlorophyta
Class: Ulvophyceae
Order:Ulvales
Family:Ulvaceae

Description
Size: Plants up to 50 cm high

Thallus unbranched, seldom with a few basal branches, but more often oblong to oblanceolate in ouline, tubular and inflated or compressed with two layers loosely adnate and with hollow margins, more or less wrinkled and lubricous, medium to yellowish green. The axis gradually tapering into the short stipe, often crenate just above the small disciform holdfast, from which seldom diminutive new thalli arise. Apex often opened before the thallus becomes fertile.

Cells in middle and apical region irregularly polygonal with 4-6 rounded to angular corners. In fully grown plants, in the apical region often more rounded than in the middle region. The cells show mostly unequal division and are arranged without order. Parietal chloroplast structure was observed by numerous large starch grains.

Most plants are dioecious gametophytes, producing 2 flagellate gametes. They are positively phototactic and are able to germinate without fusion. Sporophytes produce big 4-flagellate zoospores which are also positively phototactic.
