Red algae
Gracilariopsis longissima
Family Gracilariaceae - marine algae (red)
Distinguishing Characteristics |
Marine red algae; color purplish red to gray to translucent green; plant body (thallus) very bushy, becoming less bushy with age; branches fleshy, repeatedly dividing, occasionally dichotomously (into 2 branches). up to 2 mm (1/10 in) in width, round in cross-section, tapering distally; swollen bump-like fruiting bodies (cystocarps) may be numerous, scattered all over the branches. |
Similar Species |
Other Gracilariaceae in our area have flattened branches (as opposed to round) or are calcareous (hardened, not fleshy). The red algae may also look similar to the sauerkraut bryozoan, Zoobotryon verticillatum, but the bryozoan is flaccid, not firm, will collapse when branches are squeezed. |
