Chaetomorpha vieillardii (Kützing ) M. J. Wynne 2011: 112, figs 1, 2 a, b

Plants leaf green to dark green forming unattached, loose tangled clumps of fairly tough, curled, stiffish, unbranched, septate filaments. Filaments 350-600 µm in diameter, cells visible to the naked eye, thick-walled, 1-1.5 x as long as broad.

Collections, ecology and regional distribution

Recorded from Port Alfred to northern Kwazulu-Natal (39-58). Found in the eulittoral zone and rock pools, often entangled with other algae. (But see Note 2 below).

World distribution: Widespread in warm temperate and tropical seas (Guiry & Guiry 2012).

Syntype localities: Trieste and Venice, Italy; England (Silva et al. 1996).

Note1: This species was previously known as Chaetomorpha crassa Kützing.

Note 2: There are several specimens in BOL (as C. crassa) but most appear to be coiled and cannot be clearly distinguished from C. spiralis. As a result we are uncertain as to whether this species occurs on the south coast. C. vieillardii is unattached, while C. spiralis is attached and narrows towards the base.
