Chae<strong>to</strong>morpha linum<br />

This is an unbranched filament with a reticulate or<br />

network-like chloroplast which generally fills <strong>the</strong><br />

whole cell with colour with numerous pyrenoids<br />

present within each cells. The cells tend <strong>to</strong> be as<br />

long as broad or slightly longer and are often<br />

barrel shaped. This species of Chae<strong>to</strong>morpha has<br />

a filament width of between 100-300um. It takes<br />

<strong>the</strong> appearance of thick, <strong>to</strong>ugh, wiry floating<br />

masses, like green garden wire or wire wool and is<br />

located on <strong>the</strong> upper or mid shore on open rock<br />

surfaces or in shallow rockpools and often in<br />

dense clumps. It may form mat-like blooms on soft<br />

sediments in estuaries<br />
